3.26 LAB: Leap Year A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are: 1) The year must be divisible by 4 2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400 Some example leap years are 1600, 1712, and 2016. Write a program that takes in a year and determines whether that year is a leap year. Ex: If the input is: 1712 the output is: 1712 - leap year
Answer:
year = int(input("Enter a year: "))
if (year % 4) == 0:
if (year % 100) == 0:
if (year % 400) == 0:
print(str(year) + " - leap year")
else:
print(str(year) +" - not a leap year")
else:
print(str(year) + " - leap year")
else:
print(str(year) + "- not a leap year")
Explanation:
*The code is in Python.
Ask the user to enter a year
Check if the year mod 4 is 0 or not. If it is not 0, then the year is not a leap year. If it is 0 and if the year mod 100 is not 0, then the year is a leap year. If the year mod 100 is 0, also check if the year mod 400 is 0 or not. If it is 0, then the year is a leap year. Otherwise, the year is not a leap year.
A list based on a simple array (standard array implementation) is preferable to a dynamically allocated list for the following reasons.
A. Insertions and deletions require less work.
B. You are guaranteed a space to insert because it is already allocated.
C. You can take advantage of random-access typically.
D You can mix and match the types of the items on the list. E. (b) and (c).
F. All of the above.
Answer:
A. Insertions and deletions require less work.
C. You can take advantage of random access typically
D. You can mix and match the types of the items on the list.
Explanation:
Standard array implementation is a process in which number of items are of same type and index is restricted at a certain range. This is preferable to dynamic allocated list because it requires less work in insertion and deletions. A dynamically allocated array does not use the fixed array size declaration.
NAT ________. allows a firm to have more internal IP addresses provides some security both allows a firm to have more internal IP addresses and provides some security neither allows a firm to have more internal IP addresses nor provides some security
Answer:
NAT provides some security but allows a firm to have more internal IP addresses
Explanation:
NAT ( network address translation) this is a process where a network system usually a firewall assigns a public IP address to an internal computer used in a private network. it limits the number of public IP address a company operating a private network for its computer can have and this is very economical also limits the exposure of the company's private network of computers. the computers can access information within the private network using multiple IP addresses but it is safer to access external information using one public IP address
A security analyst is interested in setting up an IDS to monitor the company network. The analyst has been told there can be no network downtime to implement the solution, but the IDS must capyure all of the network traffic. Which of the following should be used for the IDS implementation?
a. Network tap
b. Honeypot
c. Aggregation
d. Port mirror
Answer:
d. Port mirror
Explanation:
Port mirroring is a method to monitor network traffic and it is used in the Intrusion Detection Systems. It is also called Switched Port Analyzer and is used to analyse the network errors. This technique basically copies the network packets and sends or transmits these copied packed from one port to another in a network device such as a switch. This means that this technique is used to copy the network packets from one switch port and send the copy of these packets to another port where these packets are monitored. This is how it analyses the network errors and incoming traffic for irregular behavior and also this can be done without affecting the normal operation of the switch and other network processes. It is simple, inexpensive and easy to establish and use. The most important advantage of using mirrored ports is that it catches the traffic on several ports at once or can capture all of the network traffic.
In order to place something into a container you must:_______.
a. double-click on the container and type a command.
b. drag the container onto the materials or instruments shelf.
c. double-click on the material or the instrument.
d. click on the material or instrument and drag it onto the container.
Answer:
Option (d) is the correct answer to this question.
Explanation:
The container is a class, data structure, or abstract data type, the instances of which are compilations of many other particles. In several other words, they store objects in an ordered manner that meets strict rules about access. The reviewing information depends on the number of objects (elements) contained therein. To put any material or instrument in the container, it would be easy to select the material or instrument by clicking them and then dragging them onto the container. The other option won't be able to perform the required task.Other options are incorrect because they are not related to the given scenario.
Write a program that prompts the user to enter integers in the range 1 to 50 and counts the occurrences of each integer. The program should also prompt the user for the number of integers that will be entered. As an example, if the user enters 10 integers (10, 20, 10, 30, 40, 49, 20, 10, 25, 10), the program output would be:
Answer:
import java.util.Scanner; public class Main { public static void main(String[] args) { int num[] = new int[51]; Scanner input = new Scanner(System.in); System.out.print("Number of input: "); int limit = input.nextInt(); for(int i=0; i < limit; i++){ System.out.print("Input a number (1-50): "); int k = input.nextInt(); num[k]++; } for(int j=1; j < 51; j++){ if(num[j] > 0){ System.out.println("Number of occurrence of " + j + ": " + num[j]); } } } }Explanation:
The solution is written in Java.
Firstly, create an integer array with size 51. The array will have 51 items with initial value 0 each (Line 5).
Create a Scanner object and get user entry the number of input (Line 6-7).
Use the input number as the limit to control the number of the for loop iteration to repeatedly get integer input from user (Line 9-13). Whenever user input an integer, use that integer, k, as the index to address the corresponding items in the array and increment it by one (LINE 11-12).
At last, create another for loop to iterate through each item in the array and check if there is any item with value above zero (this means with occurrence at least one). If so, print the item value as number of occurrence (Line 14-17).
(Convert milliseconds to hours, minutes, and seconds) Write a function that converts milliseconds to hours, minutes, and seconds using the following header: def convertMillis(millis): The function returns a string as hours:minutes:seconds. For example, convertMillis(5500) returns the string 0:0:5, convertMillis(100000) returns the string 0:1:40, and convertMillis(555550000) returns the string 154:19:10. Write a test program that prompts the user to enter a value for milliseconds and displays a string in the format of hours:minutes:seconds. Sample Run Enter time in milliseconds: 555550000 154:19:10
Answer:
I am writing the Python program. Let me know if you want the program in some other programming language.
def convertMillis(millis): #function to convert milliseconds to hrs,mins,secs
remaining = millis # stores the value of millis to convert
hrs = 3600000 # milliseconds in hour
mins = 60000 # milliseconds in a minute
secs = 1000 #milliseconds in a second
hours =remaining / hrs #value of millis input by user divided by 360000
remaining %= hrs #mod of remaining by 3600000
minutes = remaining / mins # the value of remaining divided by 60000
remaining %= mins #mod of remaining by 60000
seconds = remaining / secs
#the value left in remaining variable is divided by 1000
remaining %= secs #mod of remaining by 1000
print ("%d:%d:%d" % (hours, minutes, seconds))
#displays hours mins and seconds with colons in between
def main(): #main function to get input from user and call convertMillis() to #convert the input to hours minutes and seconds
millis=input("Enter time in milliseconds ") #prompts user to enter time
millis = int(millis) #converts user input value to integer
convertMillis(millis) #calls function to convert input to hrs mins secs
main() #calls main() function
Explanation:
The program is well explained in the comments mentioned with each line of code. The program has two functions convertMillis(millis) which converts an input value in milliseconds to hours, minutes and seconds using the formula given in the program, and main() function that takes input value from user and calls convertMillis(millis) for the conversion of that input. The program along with its output is attached in screenshot.
A software company assesses its developers more on their client support skills rather than their development skills. Which of the following terms would best describe the software company's performance management process?
A. Deficient
B. Contaminated
C. Unreliable
D. Inconsistent
E. Unspecified
Answer:
B. Contaminated
Explanation:
Based on the information provided regarding the scenario it seems that the software company's performance management process can be best described as contaminated. This occurs when the criterion of measurement for the employee performance includes aspects of performance that are not part of the job. Which in this case the main role of the employees is to apply their development skills in order to improve the software and not focus on their client support skills, but instead the "client support skills" is what the company is basing their performance review on.
The weekly pay for an employee is determined based on the following parameters:
Standard work hours by week is 40 hours.
Hourly pay rate is $10.00 per hour
Overtime hours are paid at time and a half the rate (that is $15.00 per hour).
Design and implement a program (name it WeeklyPay) that read number of hours worked per week (as integer value), prints out the entered hours, and then prints out the gross earning. Organized your output following these sample runs.
Sample run 1:
You entered 20 hours.
Gross earning is $200.0
Sample run 2:
You entered 40 hours.
Gross earning is $400.0
Sample run 3:
You entered 50 hours.
Gross earning is $550.0

lettergrade("Maths Class: ",maths)
lettergrade("English Class: ",english)
lettergrade("PE Class: ",pe)
lettergrade("Science Class: ",science)
lettergrade("Arts Class: ",arts)
Explanation:
The program makes the following assumptions:
Scores between 90–100 has letter grade A
Scores between 80–89 has letter grade B
Scores between 70–79 has letter grade C
Scores between 60–69 has letter grade D
Scores between 0–69 has letter grade E
Line by Line explanation
This line defines the lettergrade functions; with two parameters (One for subject or class and the other for the score)
def lettergrade(subject,score):
This line prints the the score obtained by the student in a class (e.g. Maths Class)
print(subject+": "+str(score))
The italicized determines the letter grade using if conditional statement
This checks if score is between 90 and 100 (inclusive); if yes, letter grade A is printed
if score >= 90 and score <= 100:
print("Letter Grade: A")
This checks if score is between 80 and 89 (inclusive); if yes, letter grade B is printed
elif score >= 80 and score <= 89:
print("Letter Grade: B")
This checks if score is between 70 and 79 (inclusive); if yes, letter grade C is printed
elif score >= 70 and score <= 79:
print("Letter Grade: C")
This checks if score is between 60 and 69 (inclusive); if yes, letter grade D is printed
elif score >= 60 and score <= 69:
print("Letter Grade: D")
This checks if score is between 0 and 59 (inclusive); if yes, letter grade F is printed
elif score >= 0 and score <= 59:
print("Letter Grade: F")
If input score is less than 0 or greater than 100, "Invalid Score" is printed
else:
print("Invalid Score")
This line prompts the user for score in Maths class
maths = int(input("Maths Score: "))
This line prompts the user for score in English class
english = int(input("English Score: "))
This line prompts the user for score in PE class
pe = int(input("PE Score: "))
This line prompts the user for score in Science class
science = int(input("Science Score: "))
This line prompts the user for score in Arts class
arts = int(input("Arts Score: "))
The next five statements is used to call the letter grade function for each class
lettergrade("Maths Class: ",maths)
lettergrade("English Class: ",english)
lettergrade("PE Class: ",pe)
lettergrade("Science Class: ",science)
lettergrade("Arts Class: ",arts)
Define the following terms, as they pertain to website planning: goals, objectives, target audience, and purpose statement. Explain the influence on society of inexpensive Internet access and access to the web.
Answer:
Please see explanations below
Explanation:
Goals; These are the outcomes that a website planning intends to achieve within a stipulated time, i.e weeks, months or years.
Objectives; These are the methods taken, through which the website planning goals will be achieved.
Target audience; These are the specific group of people that are intended to be reached for the website planning. The targeted audience could be identified based on age range, academic background or qualification, gender or marital status.
Purpose statement; This refers to an explanation of the website's planning goals, which is formally written and also shows the main objectives identified with the goals.
The Influence on society of inexpensive internet access and access to the web are numerous; yet it provide information that are not readily accessible by individuals before using the internet. For information to be accessed through internet access by all and sundry, it must come at little or no cost, which is what is currently obtainable in most part of the world.
Moreover, inexpensive access to the internet and web also improve quality of knowledge in addition to the existing ones through research, which is mostly done through the internet.
However, there are also downside of inexpensive access to the internet and web which now depends on whichever individuals want. For instance not every information on the website are true or correct. The right thing to be done is to further search and compare several ones until the right one is found.
2.3 Write a program to prompt the user for hours and rate per hour using input to compute gross pay. Use 35 hours and a rate of 2.75 per hour to test the program (the pay should be 96.25). You should use input to read a string and float() to convert the string to a number. Do not worry about error checking or bad user data.
Answer:
The programming language is not stated; However this program will be written using Python programming language
Comments are not used; See Explanation Section for line by line explanation of the code
hours = float(input("Hours: "))
rate = float(input("Rate per hour: "))
pay = hours * rate
print(pay)
Explanation:
The first line of the code prompts the user for hour.
The input is converted from string to float
hours = float(input("Hours: "))
The next line prompts the user for hour.
It also converts input from string to float
rate = float(input("Rate per hour: "))
Pay is calculated by multiplying hours by rate; This is implemented using the next line
pay = hours * rate
The calculated value of pay is displayed using the next line
print(pay)
When the program is tested by the given parameters in the question
hours = 35
rate = 2.75
The printed value of pay is 96.25

Complete a prewritten C++ program for a carpenter who creates personalized house signs. The program is supposed to compute the price of any sign a customer orders, based on the following facts:
The charge for all signs is a minimum of $35.00.
The first five letters or numbers are included in the minimum charge; there is a $4 charge for each additional character.
If the sign is made of oak, add $20.00. No charge is added for pine.
Black or white characters are included in the minimum charge; there is an additional $15 charge for gold-leaf lettering.
Instructions:
Ensure the file named HouseSign.cppis open in the code editor. You need to declare variables for the following, and initialize them where specified:
A variable for the cost of the sign initialized to 0.00 (charge).
A variable for the number of characters initialized to 8 (numChars).
A variable for the color of the characters initialized to "gold" (color).
A variable for the wood type initialized to "oak" (woodType).
Write the rest of the program using assignment statements and ifstatements as appropriate. The output statements are written for you.
Answer:
#include <iostream>
#include <string>
using namespace std;
int main()
{
double charge = 0.00;
int numChars = 8;
string color = "gold";
string woodType = "oak";
if(numChars > 5){
charge += (numChars - 5) * 4;
}
if(woodType == "oak"){
charge += 20;
}
if(color == "gold"){
charge += 15;
}
charge += 35;
cout << "The charge is: $" << charge << endl;
return 0;
}
Explanation:
Include the string library
Initialize the variables as specified
Check if the number of characters is greater than 5 or not. If it is, add 4 to the charge for each character that is greater than 5
Check if the sign is made of oak or not. If it is, add 20 to the charge
Check if the color is gold or not. If it is, add 35 to the charge
Add the minimum cost to the charge
Print the charge
In this exercise we have to use the knowledge of the C++ language to write the code, so we have to:
The code is in the attached photo.
So to make it easier the code can be found at:
#include <iostream>
#include <string>
using namespace std;
int main()
{
double charge = 0.00;
int numChars = 8;
string color = "gold";
string woodType = "oak";
if(numChars > 5){
charge += (numChars - 5) * 4;
}
if(woodType == "oak"){
charge += 20;
}
if(color == "gold"){
charge += 15;
}
charge += 35;
cout << "The charge is: $" << charge << endl;
return 0;

11.19 (Constructor Failure) Write a program that shows a constructor passing information about constructor failure to an exception handler. Define class SomeClass, which throws an Exception in the constructor. Your program should try to create an object of type SomeClass and catch the exception that’s thrown from the constructor
Answer:
You absolutely should throw an exception from a constructor if you're unable to create a valid object. This allows you to provide proper invariants in your class. ... Throw an exception if you're unable to initialize the object in the constructor, one example are illegal arguments.
Explanation:
Error codes cannot be used in constructors since they lack a return type. Therefore, throwing an exception is the most effective technique to indicate constructor failure. Here is a workaround if you don't have or are unwilling to use exceptions.
What constructor passing information, constructor failure?When an exception is thrown in a constructor, memory for the actual object has already been set aside before the constructor is even invoked. Therefore, after the exception is thrown, the compiler will immediately deallocate the memory the object was using.
There are two solutions to that: Simple and conventional approach: Use arrows. To make use of a two-stage construction, use a custom “construct” function after a default constructor that cannot throw exceptions.
Therefore, The constructor has the ability to “zombie” an object if it fails.

You’ve just finished training an ensemble tree method for spam classification, and it is getting abnormally bad performance on your validation set, but good performance on your training set. Your implementation has no bugs. Define various reasons that could be causing the problem?
Answer:
The various reasons that could be a major problem for the implementation are it involves a large number of parameters also, having a noisy data
Explanation:
Solution
The various reasons that could be causing the problem is given as follows :
1. A wide number of parameters :
In the ensemble tree method, the number of parameters which are needed to be trained is very large in numbers. When the training is performed in this tree, then the model files the data too well. When the model has tested against the new data point form the validation set, then this causes a large error because the model is trained completely according to the training data.2. Noisy Data:
The data used to train the model is taken from the real world . The real world's data set is often noisy i.e. contains the missing filed or the wrong values. When the tree is trained on this noisy data, then it sets its parameters according to the training data. As regards to testing the model by applying the validate set, the model gives a large error of high in accuracy y.
Going to Grad School! In the College of Computing and Software Engineering, we have an option for students to "FastTrack" their way into their master’s degree directly from undergraduate. If you have a 3.5 GPA and graduate from one of our majors, you can continue on and get your masters without having to do a lot of the paperwork. For simplification, we have four undergraduate degrees: CS, SWE, IT, and CGDD – and three masters programs: MSCS, MSSWE and MSIT. For this assignment, you’re going to ask the user a few questions and determine if they qualify for the FastTrack option.
Sample Output:
Major: Frogmongering
GPA: 3.9
Great GPA, but apply using the regular application.
Sample Output #2:
Major: SWE
GPA: 3.3
Correct major, but GPA needs to be higher.
Sample Output #3:
Major: IT
GPA: 3.5
You can FastTrack.
Sample Output #4:
Major: Study Studies
GPA: 0.4
Talk to one of our advisors about whether grad school is for you.
Answer:
The programming language is not stated. However, I'll answer this question using Python programming language.
The program uses no comments; find explanation below
i = 0
while not (i == 4):
print("Sample Run: #"+str(i+1))
Major = input("Major: ")
GPA = float(input("GPA: "))
if not (Major.upper() == "SWE" or Major.upper() == "IT" or Major.upper() == "CGDD" or Major.upper() == "CS"):
if GPA >= 3.50:
print("Great GPA, but apply using the regular application")
else:
print("Talk to one of our advisors about whether grad school is for you")
if (Major.upper() == "SWE" or Major.upper() == "IT" or Major.upper() == "CGDD" or Major.upper() == "CS"):
if GPA >= 3.50:
print("You can FastTrack.")
else:
print("Correct major, but GPA needs to be higher.")
i = i + 1
Explanation:
Line 1 of the program initializes the sample run to 0
Line 2 checks if sample run is up to 4;
If yes, the program stops execution else, it's continues execution on the next line
Line 3 displays the current sample run
Line 4 and 5 prompts user for Major and GPA respectively
Line 6 to 10 checks is major is not one of CS, SWE, IT, and CGDD.
If major is not one of those 4 and GPA is at least 3.5, the system displays "Great GPA, but apply using the regular application"
If major is not one of those 4 and GPA is less than 3.5, the system displays "Talk to one of our advisors about whether grad school is for you"
Line 11 to 15 checks is major is one of CS, SWE, IT, and CGDD.
If major is one of those 4 and GPA is at least 3.5, the system displays "You can Fastrack"
If major is one of those 4 and GPA is less than 3.5, the system displays "Correct major, but GPA needs to be higher."
The last line of the program iterates to the next sample run
Write a program that displays, 10 numbers per line, all the numbers from 100 to 200 that are divisible by 5 or 6, but not both. The numbers are separated by exactly one space
My Code:
count = 0
for i in range (100, 201):
if (i %6==0 and i %5!=0) or (i%5==0 and i%6!=0):
print(str(i), "")
count = count + 1
if count == 10:
string = str(i) + str("")
print(string)
count = 0
Any way to put the numbers 10 per line?
Answer & Explanation:
To print 10 on a line and each number separated by space; you make the following modifications.
print(str(i)+" ",end=' ')
str(i)-> represents the actual number to be printed
" "-> puts a space after the number is printed
end = ' ' -> allows printing to continue on the same line
if(count == 10):
print(' ')
The above line checks if count variable is 10;
If yes, a blank is printed which allows printing to start on a new line;
The modified code is as follows (Also, see attachment for proper indentation)
count = 0
for i in range(100,201):
if(i%6 == 0 and i%5!=0) or (i%5 ==0 and i%6!=0):
print(str(i)+" ",end=' ')
count = count + 1
if(count == 10):
print(' ')
count = 0
Give an example of a function from N to N that is: Hint: try using absolute value, floor, or ceiling for part (b). (a) one-to-one but not onto (b) onto but not one-to-one (c) neither one-to-one nor onto
Answer:
Let f be a function
a) f(n) = n²
b) f(n) = n/2
c) f(n) = 0
Explanation:
a) f(n) = n²
This function is one-to-one function because the square of two different or distinct natural numbers cannot be equal.
Let a and b are two elements both belong to N i.e. a ∈ N and b ∈ N. Then:
f(a) = f(b) ⇒ a² = b² ⇒ a = b
The function f(n)= n² is not an onto function because not every natural number is a square of a natural number. This means that there is no other natural number that can be squared to result in that natural number. For example 2 is a natural numbers but not a perfect square and also 24 is a natural number but not a perfect square.
b) f(n) = n/2
The above function example is an onto function because every natural number, let’s say n is a natural number that belongs to N, is the image of 2n. For example:
f(2n) = [2n/2] = n
The above function is not one-to-one function because there are certain different natural numbers that have the same value or image. For example:
When the value of n=1, then
n/2 = [1/2] = [0.5] = 1
When the value of n=2 then
n/2 = [2/2] = [1] = 1
c) f(n) = 0
The above function is neither one-to-one nor onto. In order to depict that a function is not one-to-one there should be two elements in N having same image and the above example is not one to one because every integer has the same image. The above function example is also not an onto function because every positive integer is not an image of any natural number.
Write a loop that reads strings from standard input where the string is either "land", "air", or "water". The loop terminates when "xxxxx" (five x characters) is read in. Other strings are ignored. After the loop, your code should print out 3 lines: the first consisting of the string "land:" followed by the number of "land" strings read in, the second consisting of the string "air:" followed by the number of "air" strings read in, and the third consisting of the string "water:" followed by the number of "water" strings read in. Each of these should be printed on a separate line. Use the up or down arrow keys to change the height.
Answer:
count_land = count_air = count_water = 0
while True:
s = input("Enter a string: ")
if s == "xxxxx":
break
else:
if s == "land":
count_land += 1
elif s == "air":
count_air += 1
elif s == "water":
count_water += 1
print("land: " + str(count_land))
print("air: " + str(count_air))
print("water: " + str(count_water))
Explanation:
*The code is in Python
Initialize the variables
Create a while loop that iterates until a specific condition is met. Inside the loop, ask the user to enter the string. If it is "xxxxx", stop the loop. Otherwise, check if it is "land", "air", or "water". If it is one of the given strings, increment its counter by 1
When the loop is done, print the number of strings entered in the required format
1. (1 point) Which flag is set when the result of an unsigned arithmetic operation is too large to fit into the destination? 2. (1 point) Which flag is set when the result of a signed arithmetic operation is either too large or too small to fit into the destination? 3. (1 point) Which flag is set when an arithmetic or logical operation generates a negative result?
Answer:
(1) Carry flag (2) Overflow flag (3) Sign or negative Flag
Explanation:
Solution
(1) The carry flag : It refers to the adding or subtracting. a two registers has a borrow or carry bit
(2) The over flow flag: This flag specify that a sign bit has been modified during subtracting or adding of operations
(3) The sign flag: This is also called a negative sign flag is a single bit status in a register that specify whether the last mathematical operations generated a value to know if the most significant bit was set.
What feature in the Windows file system allows users to see only files and folders in a File Explorer window or in a list of files from the dir command to which they have been given at least read permission?
Answer:
Access based enumeration
Explanation:
The access based enumeration is the feature which helps the file system to allow users for seeing the files and folders for which they have read access from the direct command.
Access based enumeration: This feature displays or shows only the folders and files that a user has permissions for.
If a user do not have permissions (Read) for a folder,Windows will then hide the folder from the user's view.
This feature only function when viewing files and folders are in a shared folder. it is not active when viewing folders and files in a local system.
A system developer needs to provide machine-to-machine interface between an application and a database server in the production enviroment. This interface will exchange data once per day. Which of the following access controll account practices would BESt be used in this situation?
a. Establish a privileged interface group and apply read -write permission.to the members of that group.
b. Submit a request for account privilege escalation when the data needs to be transferred
c. Install the application and database on the same server and add the interface to the local administrator group.
d. Use a service account and prohibit users from accessing this account for development work
Answer:
The correct option is (d) Use a service account and prohibit users from accessing this account for development work
Explanation:
Solution
As regards to the above requirement where the application and database server in the production environment will need to exchange the data once ever day, the following access control account practices would be used in this situation:
By making use of a service account and forbids users from having this account for development work.
The service account can be useful to explicitly issue a security context for services and thus the service can also access the local and the other resources and also prohibiting the other users to access the account for the development work.
Submitting an adhoc request daily is not a choice as this is required daily. Also, the servers can be different and cannot be put in one place. and, we cannot make use of the read-write permission to the members of that group.
What is
relation degree.
Answer:
Explanation:
The degree of relationship can be defined as the number of occurrences in one entity that is associated with the number of occurrences in another entity. There is the three degree of relationship: One-to-one (1:1) One-to-many (1:M)
Write a converter program for temperatures. This program should prompt the user for a temperature in Celsius. It should then convert the temperature to Fahrenheit and display it to the screen. Finally, it should convert the Fahrenheit temperature to Kelvin and display that to the screen.
Answer:
c = float(input("Enter the temperature in Celsius: "))
f = c * 1.8 + 32
print("The temperature in Fahrenheit: " + str(f))
k = (f - 32) / 1.8 + 273.15
print("The temperature in Kelvin: " + str(k))
Explanation:
*The code is in Python.
Ask the user to enter the temperature in Celsius
Convert the Celsius to Fahrenheit using the conversion formula and print it
Convert the Fahrenheit to Kelvin using the conversion formula and print it
Many treadmills output the speed of the treadmill in miles per hour (mph) on the console, but most runners think of speed in terms of a pace. A common pace is the number of minutes and seconds per mile instead of mph. Write a program that starts with a quantity in mph and converts the quantity into minutes and seconds per mile. As an example, the proper output for an input of 6.5 mph should be 9 minutes and 13.8 seconds per mile. If you need to convert a double to an int, which will discard any value after the decimal point, then you may use intValue
Answer:
This question is answered using C++ programming language.
This program does not make use of comments; However, see explanation section for detailed line by line explanation.
The program starts here
#include <iostream>
using namespace std;
int main()
{
double quantity,seconds;
int minutes;
cout<<"Quantity (mph): ";
cin>>quantity;
minutes = int(60/quantity);
cout<<minutes<<" minutes and ";
seconds = (60/quantity - int(60/quantity))*60;
printf("%.1f", seconds);
cout<<" seconds per mile";
return 0;
}
Explanation:
The following line declares quantity, seconds as double datatype
double quantity,seconds;
The following line declares minutes as integer datatype
int minutes;
The following line prompts user for input in miles per hour
cout<<"Quantity (mph): ";
User input is obtained using the next line
cin>>quantity;
The next line gets the minute equivalent of user input by getting the integer division of 60 by quantity
minutes = int(60/quantity);
The next statement prints the calculated minute equivalent followed by the string " minuted and " without the quotes
cout<<minutes<<" minutes and ";
After the minutes has been calculated; the following statement gets the remainder part; which is the seconds
seconds = (60/quantity - int(60/quantity))*60;
The following statements rounds up seconds to 1 decimal place and prints its rounded value
printf("%.1f", seconds);
The following statement prints "seconds per mile" without the quotes
cout<<" seconds per mile";
Following are the program to the given question:
Program Explanation:
Defining the header file.Defining the main method.Inside the method, three double variables "mph, sec, and min_per_mile", and one integer variable "min" is defined. After defining a variable "mph" is defined that inputs value by user-end.After input value, "sec, min_per_mile, and min" is defined that calculates the value and prints its calculated value.Program:
#include<iostream>//header file
using namespace std;
int main()//defining main method
{
double mph,sec,min_per_mile;//defining a double variable
int min;//defining integer variable
cout<<"Enter the speed of the treadmill in mph:";//print message
cin>>mph;//input double value
min_per_mile=(1/mph)*60;//defining a double variable that calculates minutes per mile
min=static_cast<int>(min_per_mile);//defining int variable that converts min_per_mile value into integer
sec=(min_per_mile-min)*60;//defining double variable that calculates seconds per mile value
cout<<"A common pace is the "<<min<<" minutes and "<<sec<<" seconds per mile"<<endl;//print calculated value with message
return 0;
}

Given positive integer numInsects, write a while loop that prints that number doubled without reaching 100. Follow each number with a space. After the loop, print a newline. Ex: If numInsects = 8, print:
8 16 32 64
#include
using namespace std;
int main() {
int numInsects = 0;
numInsects = 8; // Must be >= 1
while (numInsects < 100) {
numInsects = numInsects * 2;
cout << numInsects << " ";
}
cout << endl;
return 0;
}
So my question is what am I doing wrong?
Answer:
The cout<<numInsects<<""; statement should be placed before numInsects = numInsects * 2; in the while loop.
Explanation:
Your program gives the following output:
16 32 64 128
However it should give the following output:
8 16 32 64
Lets see while loop to check what you did wrong in your program:
The while loop checks if numInsects is less than 100. It is true as numInsects =8 which is less than 100.
So the body of while loop executes. numInsects = numInsects * 2; statement in the body multiplies the value of numInsects i.e 8 with 2 and then cout << numInsects << " "; prints the value of numInsects AFTER the multiplication with 2 is performed. So 8 is not printed in output but instead 16 (the result of 8*2=16) is printed as the result of first iteration.
So lets change the while loop as follows:
while (numInsects < 100) {
cout << numInsects << " ";
numInsects = numInsects * 2;
Now lets see how it works.
The while loop checks if numInsects is less than 100. It is true as numInsects =8 which is less than 100
So the body of while loop executes. cout << numInsects << " "; first prints the value of numInsects i.e. 8. Next numInsects = numInsects * 2; multiplies the value of numInsects i.e 8 with 2. So first 8 is printed on the output screen. Then the multiplication i.e. 8*2=16 is performed as the result of first iteration. So now value of numInsects becomes 16.
Next the while loop condition numInsects < 100 is again checked. It is true again as 16<100. Now cout << numInsects << " "; is executed which prints 16. After this, the multiplication is again performed and new value of numInsects becomes 32 at second iteration. This is how while loops continues to execute.
So this while loop stops when the value of numInsects exceeds 100.
