Describe any five GSM PLMN basic services?
Answer:
Your answer can be found in the explanation below.
Explanation:
GSM is the abbreviation for Global System for Mobile communication. Its purpose is to transmit voice and data services over a range. It is a digital cellular technology.
PLMN is the abbreviation for Public Land Mobile network. It is defined as the wireless communication service or combination of services rendered by a telecommunication operator.
The plmn consists of technologies that range from Egde to 3G to 4G/LTE.
PLMN consists of different services to its mobile subscribers or users but for the purpose of this question, i will be pointing out just 5 of them alongside its definitions.
1. Emergency calls services to fire or police: Plmn provides us with the option to make emergency calls in the event of any accident or fire incident, etc.It is available on devices either when locked or unlocked.
2. Voice calls to/from other PLMN: This entails the putting of calls across to persons we cannot reach very quickly. PLMN helps to connect persons through its network of from other networks thus making communication easier.
3. Internet connectivity: PLMN provieds us with internet services through wifi or bundles that enable us have access to the internet as well as help us communicate with people and loved ones over a distance. Internet service are possble either on GPRS or 3G or 4G networks.
4. SMS service: SMS means short messaging service. This is also know as text messages. PLMN allows us to be able to send short messages to people as oppposed to mails. It is mostly instant and can be sent or recieved from the same PLMN or others.
5. MMS service: Multimedia messaging service whose short form is MMS ccan be descibed as the exchange of heavier messages such as a picture or music or document but not from an email. It is availabel for use from one PLMN to another.

Answer:
Following are the statement is given below
if(updateDirection ==1) // check condition
{
++numUsers; // increments the value
}
else
{
--numUsers; // decrement the value
}
Explanation:
Following are the description of statement
Check the condition in the if block .If the "updateDirection" variable is 1 then then control moves to the if block otherwise control moves to the else block statement.In the if block the statement is "++numUsers" it means it increment the value by 1 .In the else block the statement is "--numUsers" it means it decrement the value by 1 .During a traceroute, which action does a router perform to the value in the Time To Live (TTL) field?
Answer:
During a traceroute, the router decreases the Time To Live values of the packet sent from the traceroute by one during routing, discards the packets whose Time To Live values have reached zero, returning the ICMP error message ICMP time exceeded.
Explanation:
Traceroute performs a route tracing function in a network. It is a network diagnostic commands that shows the path followed, and measures the transit delays of packets across an Internet Protocol (IP) network, from the source to the destination, and also reports the IP address of all the routers it pinged along its path. During this process, the traceroute sends packets with Time To Live values that increases steadily from packet to packet; the process is started with Time To Live value of one. At the routers, the Time To Live values of the packets is gradually decreased by one during routing, and the packets whose Time To Live values have reached zero are discarded, returning the ICMP error message ICMP Time Exceeded

The Security Configuration Wizard saves any changes that are made as a __________ security policy which can be used as a baseline and applied to other servers in the network. a. user- or server-specific b. port- or program-specific c. role- or function-specific d. file or folder-specific
Answer:
c. role- or function-specific.
Explanation:
The Security Configuration Wizard was firstly used by Microsoft in its development of the Windows Server 2003 Service Pack 1. It provides guidance to network security administrators, secure domain controllers, firewall rules and reduce the attack surface on production servers.
Security Configuration Wizard saves any changes that are made as a role- or function-specific security policy which can be used as a baseline and applied to other servers in the network.
After checking the Group policy by an administrator, any changes made as a role- or function-specific security policy by the Security Configuration Wizard (SCW) is used as a baseline and can be applied either immediately or sometimes in the future to other servers in the network after testing it in a well secured environment.
Basically, the Microsoft Security Configuration Wizard (SCW) typically help administrators in running the following;
1. Role-Based Service Configuration.
2. Registry settings.
3. Network and Firewall Security settings.
4. Auditing Policy settings.
Write a python program that asks the user to enter a student's name and 8 numeric tests scores (out of 100 for each test). The name will be a local variable. The program should display a letter grade for each score, and the average test score, along with the student's name. There are 12 students in the class.
Write the following functions in the program:
calc_average - this function should accept 8 test scores as arguments and return the average of the scores per student
determine_grade - this function should accept a test score average as an argument and return a letter grade for the score based on the following grading scale:
90-100 A
80-89 B
70-79 C
60-69 D
Below 60 F
Answer:
The program doesn't make use of comments (See Explanation)
Also the source code is attached as image to enable you see the proper format and indexing of the source code
The program using python is as follows
def calc_average(name):
score = []
sum = 0
for j in range(8):
inp = int(input("Test Score"+str(j+1)+": "))
score.append(inp)
sum = sum + inp
if inp>=90 and inp<=100:
print("A")
elif inp>=80 and inp<90:
print("B")
elif inp>=70 and inp<80:
print("C")
elif inp>=60 and inp<70:
print("D")
else:
print("F")
avg = sum/8
print("Result Details of "+name)
print("Average Score: "+str(avg))
return avg
def determine_grade(result):
if float(result) >= 90.0 and float(result) <= 100.0:
print("Letter Grade: A")
elif float(result) >= 80.0 and float(result) <90.0:
print("Letter Grade: B")
elif float(result) >= 70.0 and float(result) < 80.0:
print("Letter Grade: C")
elif float(result) >= 60.0 and float(result) < 70.0:
print("Letter Grade: D")
else:
print("Letter Grade: F")
print(" ")
for i in range(2):
name = input("Student Name: ")
result = calc_average(name)
determine_grade(result)
Explanation:
def calc_average(name): -> Declares the function calc_average(name); It accepts local variable name from the main function
score = []
-> Initialize an empty list to hold test scores
sum = 0
-> Initialize sum of scores to 0
for j in range(8):
-> Iterate from test score 1 to 8
inp = int(input("Test Score"+str(j+1)+": "))
-> This line accepts test score from the user
score.append(inp)
-> The user input is then saved in a lisy
sum = sum + inp
-> Add test scores
The following lines determine the letter grade of each test score
if inp>=90 and inp<=100:
print("A")
---
else:
print("F")
avg = sum/8 -> Calculate average of the test score
The next two lines prints the name and average test score of the student
print("Result Details of "+name)
print("Average Score: "+str(avg))
return avg
-> This line returns average to the main method
The following is the determine_grade method; it takes it parameter from the main method and it determines the letter grade depending on the calculated average
def determine_grade(result):
if float(result) >= 90.0 and float(result) <= 100.0:
print("Letter Grade: A")
elif float(result) >= 80.0 and float(result) <90.0:
print("Letter Grade: B")
elif float(result) >= 70.0 and float(result) < 80.0:
print("Letter Grade: C")
elif float(result) >= 60.0 and float(result) < 70.0:
print("Letter Grade: D")
else:
print("Letter Grade: F")
print(" ")
for i in range(2):
-> This is the main method
name = input("Student Name: ") -> A local variable stores name of the student
result = calc_average(name) -> store average of scores in variable results
determine_grade(result)-> Call the determine_grade function
In this exercise we have to use the computer language knowledge in python to write the code as:
the code is in the attached image.
In a more easy way we have that the code will be:
def calc_average(name):
score = []
sum = 0
for j in range(8):
inp = int(input("Test Score"+str(j+1)+": "))
score.append(inp)
sum = sum + inp
if inp>=90 and inp<=100:
print("A")
elif inp>=80 and inp<90:
print("B")
elif inp>=70 and inp<80:
print("C")
elif inp>=60 and inp<70:
print("D")
else:
print("F")
avg = sum/8
print("Result Details of "+name)
print("Average Score: "+str(avg))
return avg
def determine_grade(result):
if float(result) >= 90.0 and float(result) <= 100.0:
print("Letter Grade: A")
elif float(result) >= 80.0 and float(result) <90.0:
print("Letter Grade: B")
elif float(result) >= 70.0 and float(result) < 80.0:
print("Letter Grade: C")
elif float(result) >= 60.0 and float(result) < 70.0:
print("Letter Grade: D")
else:
print("Letter Grade: F")
print(" ")
for i in range(2):
name = input("Student Name: ")
result = calc_average(name)
determine_grade(result)

Write a program that determines the value of the coins in a jar and prints the total in dollars and cents. Read integer values that represent the number of quarters, dimes, nickels, and pennies. This program will require user input.
Answer:
The programming language is not stated. To answer this question, I'll make use of python programming language.
The following units of conversions is used in this program
1 quarter = $0.25
1 dime = $0.10
1 nickel = $0.05
1 penny = $0.01
$1 = 100 cents
This program makes use of few comment (See explanation for line by line explanation)
Having listed the above, the program is as follows:
#prompt user for inputs
quarters = int(input("Number of Quarters: "))
dimes = int(input("Number of Dimes: "))
nickels = int(input("Number of Nickels: "))
pennies = int(input("Number of Pennies: "))
#Convert coins to dollars
dollar = 0.25 * quarters + 0.10 * dimes + 0.05 * nickels + 0.01 * pennies
print("Dollar Equivalent")
print(str(round(dollar,2))+" dollars")
cent = dollar * 100
print("Cent Equivalent")
print(str(round(cent,2))+" cents")
Explanation:
This first line is a comment
#prompt user for inputs
This line prompts user for value of quarters in the jar
quarters = int(input("Number of Quarters: "))
This line prompts user for value of dimes in the jar
dimes = int(input("Number of Dimes: "))
This line prompts user for value of nickels in the jar
nickels = int(input("Number of Nickels: "))
This line prompts user for value of pennies in the jar
pennies = int(input("Number of Pennies: "))
Using the coin conversion listed in the answer section, the user inputs is converted to dollars in the next line
dollar = 0.25 * quarters + 0.10 * dimes + 0.05 * nickels + 0.01 * pennies
The string "Dollar Equivalent" is printed using the next line
print("Dollar Equivalent")
This line prints the dollar equivalent of the converted coins
print(str(round(dollar,2))+" dollars")
Using the coin conversion listed in the answer section, the user inputs is converted to cents in the next line
cent = dollar * 100
The string "Cent Equivalent" is printed using the next line
print("Cent Equivalent")
This line prints the cent equivalent of the converted coins
print(str(round(cent,2))+" cents")
Please note that the dollar and cent equivalents are rounded to two decimal places. Even though, it's not a requirement of the program, it's a good programming practice
You learn that in a previous security breach at GearUp, a disgruntled employee destroyed the encryption key that had been used to protect data. How will you prevent a similar data safeguard problem at GearOn
Answer:
The data can be safeguarded using key escrow procedure.
Explanation:
Key escrow basically means to store the cryptographic key in an "escrow" by a reputable trusted third party. The copy of the encryption key is kept with the third party. In case the cryptographic key gets lost or destroyed, then the key escrow service helps to access the encrypted data. It also manages the access control to the key in case the key gets lost. So this way in case of security breach at GearOn the key escrow service can be used to re-implement or access the key easily.
What is an optimal Hup?man code for the following set of frequencies, based on the first 8 Fibonacci numbers? a:1 b:1 c:2 d:3 e:5 f:8 g:13 h:21 Can you generalize your answer to find the optimal code when the frequencies are the first n Fibonacci numbers?
Answer:
Optimal Huffman code is an encoding algorithm which encodes different symbols using priority queuingExplanation:
To explain how the Optimal Huffman code works we draw the Huffman tree for the set of symbols and the leaves of the tree are symbols
Note; the right and left moves on the tree starting from the root of the tree to the leaves contain 1 and 1
Also each letter in the tree has a code word from the the root to each letter and the code is called ; Huffman codes.
h : 0
g : 10
f : 110
e : 1110
d : 11110
c : 111110

Write a complete program that reads 6 numbers and assigns True to variable isAscending if the numbers are in ascending order. Otherwise assign False to it. Display the value of isAscending. Here are three sample runs: Sample Run 1 Enter six numbers: 4 6 8 10 11 12 True Sample Run 2 Enter six numbers: 4 6 3 10 11 12 False Sample Run 3 Enter six numbers: 41 6 3 10 11 12 False Note: Your program must match the sample run exactly.
Answer:
The programming language is not stated;
For this, I'll answer your question using c++ programming language
The program does not make use of comments (See explanation for further details)
From the sample run, the input numbers are integer; So, this program assumes that all input will be integer...
Program starts here
#include<iostream>
using namespace std;
int main()
{
cout<<"Enter six numbers: ";
int Arr[6];
for(int i = 0;i<6;i++)
{
cin>>Arr[i];
}
bool flag = true;
for(int i = 0;i<6;i++)
{
for(int j = i;j<6;j++)
{
if(Arr[i]>Arr[j])
{
flag = false;
}
}
}
string isAscending;
if(flag)
{
isAscending = "True";
}
else
{
isAscending = "False";
}
cout<<isAscending;
return 0;
}
Explanation:
cout<<"Enter six numbers: "; -> This line prompts the user for input
int Arr[6]; -> The input is stored in an array; This line declares the array
The following for loop iteration is used to iterate through the array
for(int i = 0;i<6;i++)
{
cin>>Arr[i]; -> This line accepts user input
}
bool flag = true; -> A boolean variable is initialized to true
The following nested loop checks if numbers are in ascending order
for(int i = 0;i<6;i++)
{
for(int j = i;j<6;j++)
{
if(Arr[i]>Arr[j]) -> This particular if statement checks if a number is greater than the next number
{
flag = false; -> If yes, the boolean variable is changed to false
}
}
} - > The nested loop ends here
string isAscending = "True"; -> Here, isAscending is declared as string
if(flag) If boolean variable flag is true; i
{
isAscending = "True"; "True" is assigned to isAscending
}
else -> Otherwise; if boolean variable flag is no longer true; i.e if it's false
{
isAscending = "False"; -> "False" is assigned to isAscending
}
cout<<isAscending; -> The corresponding value of isAscending is printed
The complete program that reads 6 numbers and assigns True to variable isAscending if the numbers are in ascending order is as follows;
number = 0
list1 = []
while number < 6:
x = input("enter six number: ")
number += 1
list1.append(x)
if sorted(list1)==list1:
print("True")
else:
print("False")
Code explanation:The code is written in python
The variable "number" is initialise to zero.We declared an empty list to unpack our numbers.while number is less than 6, we ask the user for inputs and increased the value of number for the loop to continue. we append the users input to the list1.If the sorted value of the list1 is equals to the list1, then we print True Else we print Falselearn more on python here: https://brainly.com/question/26104476

Explanation:
Description of the code:
In the above code, two integer variable "d and y" and one string variable "m" are declared, in which the "y and m" variable is used to input the value from the user end. In the y variable, we simply input the value and print its value, but in the m variable, we input the value and used to check its value by using multiple if blocks and in this, we also check leap year value, and then assign value in "d" variable. In the last step, we print input values with the "d" variable value.Design and implement a program (name it Youth) that reads from the user an integer values repressing age (say, age). The program prints out the entered values followed by a message as follows: If age is less or equal to 21, the message is "Age is a state of mind.". Finally, the program always prints out the message "Age is a state of mind." Format the outputs following the sample runs below.
Sample run 1:
You entered: 20
Youth is a wonderful thing. Enjoy.
Age is a state of mind.
Answer:
The programming language is not stated; I'll answer this question using C++ programming language;
Another thing to note is that; the sample run is quite different from the illustration in the question; So, I'll assume the program to print "Youth is a wonderful thing. Enjoy.", if and only if age is less than or equal to 21
The program is as follows
#include<iostream>
using namespace std;
int main() {
int age;
int i =1;
start:
cout<<"Sample run: "<<i<<endl;
cout<<"You entered: ";
cin>>age;
if(age<=21) {
cout<<"Youth is a wonderful thing. Enjoy."<<endl; }
cout<<"Age is a state of mind"<<endl;
i++;
cout<<"Run another? (Y/N): ";
char resp;
cin>>resp;
if(resp=='Y')
{
goto start;
}
return 0;
}
Explanation:
Line 4 of the program declares age as integer
Line 5 declares and initializes a counter variable, i to 1
Line 6 is used as a label to start another sample run
Line 7 prints the Sample run in the following format;
Sample run 1, during the first iteration
Sample run 2, during the second iteration; and so on...
Line 8 prompts the user to supply details for age
Line 9 stores user input in variable age
Line 10 checks if age is less than or equal to 21
If true, the program outputs Youth is a wonderful thing. Enjoy., then it continues execution on line 23
Otherwise, it jumps directly to line 23 and outputs Age is a state of mind
The counter is increased by 1 on line 24
The program asks if the user wants to take another sample run on line 25
The response is saved in a char variable on line 27
If the user response is Y, the program goes to the label on line 6 to begin another iteration
Otherwise, the program is terminated.

(A perfect square is an integer like 9, 16, 25, 36 that is equal to the square of another integer (in this case 3*3, 4*4, 5*5, 6*6 respectively). Assign the sum you compute to the variable q. For example, if h is 19, you would assign 30 to q because the perfect squares (starting with 1) that are less than h are: 1, 4, 9, 16 and 30==1+4+9+16.
Answer:
import math
h = 19
total = 0
for i in range(1, h):
if math.sqrt(i) - int(math.sqrt(i)) == 0:
total += i
print(total)
Explanation:
*The code is in Python.
Initialize the h and total
Create a for loop that iterates from 1 to h. Inside the loop, check if the difference between the square root of a number and the integer part of the square root of that number is equal to 0 (This means the number is a perfect square. For example, if the number is 3, the square root is 1.73 and the integer part of this is 1, the difference is 0.73, not 0. However, if the number is 4, the square root is 2.0 and the integer part is 2, the difference is 0), add that number to the total
When the loop is done, print the total.
The performance of a client-server system is strongly influenced by two major network characteristics: the bandwidth of the network (how many bits/sec it can transport) and the latency (how many seconds it takes for the first bit to get from the client to the server). Give an example of a network that exhibits high bandwidth but also high latency. Also give an example of one that has both low bandwidth and low latency. Justify/explain your answers. (
Answer:
A bandwidth is the maximum rate of transfer of data across a given path
Latency refers to the delay of data to travel or move between a source and destination
An example of a high bandwidth and high latency network is the Satellite Internet connectivity.
An example of a low bandwidth and latency network is the telephone system connection.
Explanation:
Solution
Bandwidth: Bandwidth determines how fast data can be transferred for example, how many bits/sec it can transport.
Latency: It refers to the delay or how long it takes for data to travel between it's source and destination.
An example of a high bandwidth and high latency network is the Satellite internet connection.
Satellite internet connection: This is responsible for the connectivity of several systems, it has a high bandwidth, since satellite are in space, due to distance it has a high latency.
So, satellite internet connection is compensated with high latency and high bandwidth.
An example of a low bandwidth and low latency network is the Telephony network.
Telephone/telephony internet connection: This connection does not have much data for transfer. it has low size audio files of which a low bandwidth range. also for both end or end users to understand and talk to each other, it has low latency.
An example of a network that exhibits high bandwidth but also high latency is Satellite internet connection.
An example of one that has both low bandwidth and low latency is telephony internet connection.
Based on the provided information, we can say that Satellite internet connection posses high bandwidth but also high latency because, the fastness of data transfer is based on the bandwidth and how the data to travel between it's source and destination is based on its latency.
We can conclude that telephony internet connection has low bandwidth and low latency because of low data transfer is required.

}
Explanation:
Initialize the YEAR as a constant and set it to 2050
Initialize the currentYear as 2020, and currentAge as 38
Calculate and print the age in 2050 (Subtract the currentYear from the YEAR and add it to the currentAge)
Typical T1 voice lines have 24 channels with each capable of carrying 1 telephone conversation with "8-bit" quantization and 8,000 samples/second. If we apply this to storing a voice clip on disk, how much storage (in bits) does a 10 second clip take. 64,000 bits 640,000 bits 6,400,000 64.000.000 bits
Answer:
B. 640,000 bits
Explanation:
From the given question,
The voice line has 24 channels with each having the capacity for 1 telephone conversation with the size of 8 bits and 8, 000 samples/second.
Thus for a 10 seconds clip, the rate = 8 000 × 10
= 80 000
The rate is 80 000 samples/second.
The size of the storage in bits = rate ×8 bits
= 80 000 × 8
= 640 000 bits
Therefore, the size of the storage required for storing the video clip on disk is 640 000 bits.
House real estate summary Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (current_price * 0.051) / 12. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('{:.2f}'.format(your_value)) Ex: If the input is: 200000 210000 the output is: This house is $200000. The change is $-10000 since last month. The estimated monthly mortgage is $850.00.
Answer:
current_price = int(input("Enter the current price: "))
last_months_price = int(input("Enter the last month's price: "))
print("This house is $" + str(current_price))
print("The change is $" + str(current_price - last_months_price) + " since last month")
print("The estimated monthly mortgage is ${:.2f}".format((current_price * 0.051) / 12))
Explanation:
Ask the user to enter the current price and last month's price
Print the current price
Print the change in the price, subtract the last month's price from the current price
Print the estimated monthly mortgage, use the given formula to calculate, in required format
The common field cricket chirps in direct proportion to the current temperature. Adding 40 to the number of times a cricket chirps in a minute, then dividing by 4, gives us the temperature (in Fahrenheit degrees). Write a program that accepts as input the number of cricket chirps in fifteen seconds, then outputs the current temperature.
Answer:
chirps = int(input("Enter the number of cricket chirps in fifteen seconds: "))
temperature = chirps + 40
print("The temperature is: " + str(temperature))
Explanation:
*The code is in Python.
Ask the user to enter the number of cricket chirps in fifteen seconds
Use the given formula to calculate the temperature (Note that since the user enters the number of cricket chirps in fifteen seconds, I did not divide the sum by 4)
Print the temperature
Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string. You may assume that the string does not contain spaces and will always contain less than 50 characters.Ex: If the input is:n Mondaythe output is:1Ex: If the input is:z TodayisMondaythe output is:0Ex: If the input is:n It'ssunnytodaythe output is:2Case matters.Ex: If the input is:n Nobodythe output is:0n is different than N.C++ Code:#include #include int main(void) {/* Type your code here. */return 0;}
Answer:
Here is the C++ program:
#include <iostream> // to include input output functions
using namespace std; // to identify objects like cin cout
int counter(string userString, char character) { //function counter
int count = 0; // counts the no of times a character appears in the string
for (int i=0;i<userString.length();i++)
// loop to move through the string to find the occurrence of the character
if (userString[i] == character) //if characters is found in the string
count++; //counts the occurrence of the character in the string
return count; } //returns the no of times character occurs in the string
int main() { //start of the main() function body
string s; // stores the string entered by the user
cout<<"Enter a string: "; //prompts user to enter the string
cin>>s; //reads the string from user
char ch; //stores the character entered by the user
cout<<"Enter a character: "; //prompts user to enter a character
cin>>ch; //reads the character from user
cout << counter(s, ch) << endl; }
//calls counter function to find the number of times a character occurs in the //string
Explanation:
The counter function works as following:
It has a count variable which stores the number of occurrences of a character in the userString.
It uses a for loop which loops through the entire string.
It has i position variable which starts with the first character of the string and checks if the first character of userString matches with the required character.
If it matches the character then count variable counts the first occurrence of the character and in the userString and is incremented to 1.
If the character does not match with the first character of the userString then the loops keeps traversing through the userString until the end of the userString is reached which is specified by the length() function which returns the length of the string.
After the loop ends the return count statement is used to return the number of occurrences of the character in the userString.
The main() function prompts the user to enter a string and a character. It then calls counter() function passing string s and character ch arguments to it in order to get the number of times ch appears in s.

Answer:
for loop statement is not complete
Consider the following algorithm. for i ∈ {1,2,3,4,5,6} do ???? beep for j ∈ {1,2,3,4} do beep for k ∈ {1,2,3} do ???? for l ∈ {1,2,3,4,5} do beep for m ∈ {1,2,3,4} do ???? ???? beep How many times does a beep statement get executed?
Answer:
This is the complete question:
for i ∈ {1,2,3,4,5,6} do beep
for j ∈ {1,2,3,4} do beep
for k ∈ {1,2,3} do
for l ∈ {1,2,3,4,5} do beep
for m ∈ {1,2,3,4} do beep
Explanation:
I will explain the algorithm line by line.
for i ∈ {1,2,3,4,5,6} do beep
This statement has a for loop and i variable that can take the values from 1 to 6. As there are 6 possible values for i so the beep statement gets executed 6 times in this for loop.
for j ∈ {1,2,3,4} do beep
This statement has a for loop and j variable that can take the values from 1 to 4. As there are 4 possible values for j so the beep statement gets executed 4 times in this for loop.
for k ∈ {1,2,3} do
for l ∈ {1,2,3,4,5} do beep
There are two statements here. The above statement has a for loop and k variable that can take the values from 1 to 3. As there are 3 possible values for k so the beep statement gets executed 3 times in this for loop. The below statement has a for loop and l variable that can take the values from 1 to 5. As there are 5 possible values for l so the beep statement gets executed 5 times in this for loop. However these statement work like an inner and outer loop where the outer loop is k and inner one is l which means 1 gets executed for each combination of values of k and l. As there are three values for k and 5 possible values for l so the combinations of values of k and l is 15 because 3 * 5 = 15. Hence the beep statement gets executed 15 times.
for m ∈ {1,2,3,4} do beep
This statement has a for loop and m variable that can take the values from 1 to 4. As there are 4 possible values for m so the beep statement gets executed 4 times in this for loop.
Now lets take the sum of all the above computed beeps.
for i = 6 beeps
for j = 4 beeps
for k and l possible combinations = 15 beeps
for m = 4 beeps
total beeps = 6 + 4 + 15 + 4 = 29 beeps
Assign True to the variable is_ascending if the list numbers is in ascending order (that is, if each element of the list is greater than or equal to the previous element in the list). Otherwise, assign False with is_ascending.
Answer:
The question seem incomplete as the list is not given and the programming language is not stated;
To answer this question, I'll answer this question using Python programming language and the program will allow user input.
Input will stop until user enters 0
The program is as follows
newlist = []
print("Input into the list; Press 0 to stop")
userinput = int(input("User Input:"))
while not userinput == 0:
newlist.append(userinput)
userinput = int(input("User Input:"))
is_ascending = "True"
i = 1
while i < len(newlist):
if(newlist[i] < newlist[i - 1]):
is_ascending = "False"
i += 1
print(newlist)
print(is_ascending)
Explanation:
This line declares an empty list
newlist = []
This line prompts gives instruction to user on how to stop input
print("Input into the list; Press 0 to stop")
This line prompts user for input
userinput = int(input("User Input:"))
This next three lines takes input from the user until the user enters 0
while not userinput == 0:
newlist.append(userinput)
userinput = int(input("User Input:"))
The next line initialized "True" to variable is_ascending
is_ascending = "True"
The next 5 line iterates from the index element of the list till the last to check if the list is sorted
i = 1
while i < len(newlist):
if(newlist[i] < newlist[i - 1]):
is_ascending = "False"
i += 1
The next line prints the list
print(newlist)
The next line prints the value of is_ascending
print(is_ascending)
Implement a Java program using simple console input & output and logical control structures such that the program prompts the user to enter 5 integer scores between 0 to 100 as inputs and does the following tasks For each input score, the program determines whether the corresponding score maps to a pass or a fail. If the input score is greater than or equal to 60, then it should print "Pass", otherwise, it should print "Fail". After the 5 integer scores have been entered, the program counts the total number of passes as well as the total number of failures and prints those 2 count values with appropriate messages like "Total number of passes is: " & "Total number of failures is: ". After the 5 integer scores have been entered, the program finds the highest score as well as the lowest score and prints those 2 values with appropriate messages like "Highest score is: " & "Lowest score is: ". The program checks whether an input score is a number between 0 - 100 or not. If the input score value is otherwise or outside the above range, then it prints the error message saying "Invalid score" and prompts the user for valid input.
Answer:
import java.util.Scanner; public class Main { public static void main(String[] args) { int pass = 0; int fail = 0; int highest = 0; int lowest = 100; int counter = 0; Scanner input = new Scanner(System.in); while(counter < 5){ System.out.print("Input a score between 0 to 100: "); int score = input.nextInt(); while(score < 0 || score > 100){ System.out.println("Invalid score."); System.out.print("Input a score between 0 to 100: "); score = input.nextInt(); } if(score >= 60 ){ System.out.println("Pass"); pass++; }else{ System.out.println("Fail"); fail++; } if(highest < score ){ highest = score; } if(lowest > score){ lowest = score; } counter++; } System.out.println("Total number of passes is: " + pass); System.out.println("Total number of failures is: " + fail); System.out.println("Highest score is: " + highest); System.out.println("Lowest score is: " + lowest); } }Explanation:
Firstly, declare the necessary variables and initialize them with zero (Line 4-8). Next create a Scanner object to get user input for score (Line 10). Create a while loop by using the counter as limit (Line 12). In the while loop, prompt user to input a number between 1 - 100 (Line 13-14). Create another while loop to check the input must be between 1 - 100 or it will print invalid message and ask for user input again (Line 15-19).
Next, create an if-else statement to check if the current score is equal or above 60. If so print pass if not print fail (Line 21-27). At the same time increment the fail and pass counter.
Create another two if statement to get the current highest and lowest score and assign them to highest and lowest variables, respectively (Line 29-35).
Increment the counter by one before proceeding to the next loop to repeat the same process (Line 37).
At last, print the required output after finishing the while loop (Line 40-43).
