If the input for month is incorrect, display a message as shown in the following sample run.


SAMPLE RUN 1:

Enter a year: 2001
Enter a month: Jan
Jan 2001 has 31 days

SAMPLE RUN 2:

Enter a year: 2016
Enter a month: Feb
Feb 2016 has 29 days

SAMPLE RUN 3:

Enter a year: 2016

Enter a month: jan

jan is not a correct month name


Class Name: Exercise04_17

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

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.

Answer:

The correct answer is option (A) Roll-up summary fields

Explanation:

Solution

The feature the administrator needs to use to meet this requirement is by applying Roll-up summary fields.

A roll-up summary field :A roll-up summary field computes or determine values from associated records, for example those in a linked list. one can develop a roll-up summary field to d a value in a master record  by building the values of fields in a detail record.

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.

Answer:

The program doesn't use comments; See explanation section for detailed line by line explanation

Program starts here

def lettergrade(subject,score):

     print(subject+": "+str(score))

     if score >= 90 and score <= 100:

           print("Letter Grade: A")

     elif score >= 80 and score <= 89:

           print("Letter Grade: B")

     elif score >= 70 and score <= 79:

           print("Letter Grade: C")

     elif score >= 60 and score <= 69:

           print("Letter Grade: D")

     elif score >= 0 and score <= 59:

           print("Letter Grade: F")

     else:

           print("Invalid Score")

maths = int(input("Maths Score: "))

english = int(input("English Score: "))

pe = int(input("PE Score: "))

science = int(input("Science Score: "))

arts = int(input("Arts Score: "))

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)

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

Factors Influencing Unequal Internet Access:

1. Age: Children under 10 and adults over 60 do not enjoy the same level of access to the internet.  For children 10, their parents restrict their use of the internet.  Most adults over 60 lack the interest and competence to utilize access to the internet.

2. Sex: Men usually enjoy better access to the internet than women.  While men explore many sources of internet information, women usually restrict themselves to social media, which is usually their favorites, giving the high-level chatting that is involved in social media.

3. Nationality:  Access to the internet is not available equally in all the nations of the world.  In communist China, there are government-mandated restrictions placed on citizens.  In some sub-Saharan African countries, access to the internet is a luxury that many cannot afford and it is not easily available due to lack of basic internet infrastructure.

4. Education is another factor that influences access to the internet.  The level of education dictates whether somebody has access or not.  Many illiterate men and women who do not value the internet.  What you do not value, you do not use.  What you do not use is not accessible to you.

5. Income:  This is another important factor that influences access to the internet.  In some countries, the availability of high-speed network remains unaffordable to the majority of the population.  They only have telephone networks to use their internet access, due to the high cost of high-speed digital satellite-based networks.  Many people can only access the internet on public WiFis.

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.

Answer:

I am writing a JAVA program. Let me know if you want the program in some other programming language.

import java.util.Scanner; //to take input from user

public class HexaToBinary{ //class to convert hexa to binary number

public static void main(String[] args) {// start of main() function body

//creates instance of Scanner class

      Scanner input = new Scanner(System.in);

//prompts user to enter a hexadecimal number

System.out.print("Enter a hex digit: ");

char hexadecimal = input.nextLine().charAt(0);//reads input from user

 String binary = ""; //variable to hold corresponding binary number

/*switch statement is used to convert hexadecimal input to corresponding binary number. the switch statement has cases. Each case has a hexa decimal number. The user's input is stored in hexadecimal variable which is given as a choice parameter to switch statement. If the input matches any of the cases in switch statement, the body of that case is executed which prints the corresponding binary number otherwise invalid input message is displayed in output */

  switch (hexadecimal) {

      case '0': binary = "0"; break;

      case '1': binary = "1"; break;

      case '2': binary = "10"; break;

      case '3': binary = "11"; break;

      case '4': binary = "100"; break;

      case '5': binary = "101"; break;

      case '6': binary = "110"; break;

      case '7': binary = "111"; break;

      case '8': binary = "1000"; break;

      case '9': binary = "1001"; break;

//here both the upper and lower case letters are defined in case, so the user //can enter a hexadecimal in lowercase or uppercase

             case 'a':

             case 'A': binary = "1010"; break;

      case 'b':

             case 'B':binary = "1011"; break;

      case 'c':

             case 'C': binary = "1100"; break;

      case 'd':

             case 'D': binary = "1101"; break;

      case 'e':

             case 'E': binary = "1110"; break;

      case 'f':

             case 'F': binary = "1111"; break;

      default: System.out.println(hexadecimal + " is invalid input"); System.exit(1);   } //displays this message if user enters invalid input e.g T

    System.out.println("The binary value is " + binary); } }

//prints the corresponding binary number of the hexadecimal input

Explanation:

The program is well explained in the comments mentioned with each line of the program. Lets take an example of user input.

For example if user enters b in input then the cases of the switch statement are searched for by the program to select the corresponding binary number of the input hexadecimal. So b is present in case 'b': case 'B':binary = "1011"; break; So the value of binary is 1011 and this value is displayed on the screen with this statement System.out.println("The binary value is " + binary); So the output is: The binary value is 1011

The screenshot of output and program are attached.

The java program is as follows.

import java.lang.*;

public class Triangle

{

   //variables to hold sides of a triangle

   static double height;

   static double base;

   static double hypo;

   //method to compute hypotenuse

   static double rightTriangle(double h, double b)

   {

       return Math.sqrt(h*h + b*b);

   }

public static void main(String[] args) {

    height = 4;

    base = 3;

    hypo = rightTriangle(height, base);

 System.out.printf("The hypotenuse of the right-angled triangle is %.4f", hypo);

}

}

OUTPUT

The hypotenuse of the right-angled triangle is 5.0000

Explanation:

1. The variables to hold all the three sides of a triangle are declared as double. The variables are declared at class level and hence, declared with keyword static.

2. The method, rightTriangle() takes the height and base of a triangle and computes and returns the value of the hypotenuse. The square root of the sum of both the sides is obtained using Math.sqrt() method.

3. The method, rightTriangle(), is also declared static since it is called inside the main() method which is a static method.

4. Inside main(), the method, rightTriangle() is called and takes the height and base variables are parameters. These variables are initialized inside main().

5. The value returned by the method, rightTriangle(), is assigned to the variable, hypo.

6. The value of the hypotenuse of the triangle which is stored in the variable, hypo, is displayed to the user.

7. The value of the hypotenuse is displayed with 4 decimal places which is done using printf() method and %.4f format specifier. The number 4 can be changed to any number, depending upon the decimal places required.

8. In java, all the code is written inside a class.

9. The name of the program is same as the name of the class having the main() method.

10. The class having the main() method is declared public.

11. All the variables declared outside main() and inside another method, are local to that particular method. While the variables declared outside main() and inside class are always declared static in java.

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.

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.

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

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;

}

Answer:

s = input("Enter a string: ")

print(len(s))

print(s*10)

print(s[0])

print(s[:3])

print(s[len(s)-3:])

print(s[::-1])

if len(s) >= 7:

   print(s[6])

else:

   print("The string is not long enough")

print(s[1:len(s)-1])

print(s.upper())

print(s.replace("a", "e"))

Explanation:

*The code is in Python.

Ask the user to enter a string

Use len method to get the total number of characters

Use "*" to repeat 10 times

Use index, 0,  to get first character

Use slicing to get first three characters

Use slicing to get last three characters

Use slicing to get it in backwards

Check if the length is greater than or equal to 7. If it is, use index, 6. Otherwise, print a message.

Use slicing to remove first and last characters

Use upper method to get it in all caps

Use replace method to replace the "a" with the "e"

The program that ask the user to enter a string and print the  (a) The total number of characters in the string (b) The string repeated 10 times (c) The first character of the string (remember that string indices start at 0) (d) The first three characters of the string (e) The last three characters of the string (f) The string backwards (g) The seventh character of the string if the string is long enough and a message otherwise (h) The string with its first and last characters removed (i) The string in all caps (j) The string with every a replaced with an e

is as follows:

x = str(input("please enter a string: "))

print(len(x))

print(x*10)

print(x[0])

print(x[0:3])

print(x[-3:])

print(x[::-1])

if len(x) >= 7:

  print(x[6])

else:

  print("The string is not up to length 7")

print(x[1:-1])

print(x.upper())

print(x.replace('a', 'e'))

The first line ask the user for a string input.

Print length of the user input

Print the user input ten times.

Print the first value of the user input

print the first three string

Print the last three string

Print the reverse of the string

if the length of the user input is greater than or equals to zero, then print the 7th term of the user input.

else it will print that the string length is not up to seven.

Remove the first and the last term of the user input and print the remaining user input.

print the uppercase of the user input.

Replace a with e in the user input.

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:

Question:

Two arrays are given:  

String apples[] = {"HoneyCrisp", "DeliciousRed", "Gala", "McIntosh",  "GrannySmith"};

double prices[] = {4.50, 3.10, 2.45, 1.50, 1.20};

Write a method that finds the cheapest name of apples, and returns back a String stating what the apple name is and how much it costs. The method should take two arrays as two parameters (you do not need to make a two dimensional array out of these arrays).

Answer:

The complete java code along with the output is prrovided below.

Java Code:

public class ApplesCheap

{

   public static String Cheapest(String apples[], double prices[])

 {

       int temp = 0;

       for (int i = 0; i < apples.length; i++)

    {

         if (prices[i] < prices[temp])

          {

               temp = i;

           }

       }

       return apples[temp];

   }

public static void main(String[] args)

{

// define the array of apple names and their prices

  String apples[] = {"HoneyCrisp", "DeliciousRed", "Gala", "McIntosh", "GrannySmith"};

  double prices[] = {4.50, 3.10, 2.45, 1.50, 1.20};

// print the cheapest apple by calling the function Cheapest

  System.out.println("The cheapest apple is: " + Cheapest(apples, prices));

   }

}

Output:

The cheapest apple is: GrannySmith

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

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.
