- Which of the following is not required of a loop control variable in a correctly working loop? It is reset to its initial value before the loop ends. It is initialized before the loop starts. It is tested. It is altered in the loop body.Which kind of while loop may be broken by entering a single character or a single value into the input field? Although the loop eof, loop counter, and loop flag may all be managed, the loop sentinel cannot.Which form of while loop uses a user-supplied character or value to exit the loop? While the loop eof, loop counter, and loop flag can be managed, and the loop sentinel can be monitored,
- (python) Which command is used to exit out of a loop at any point? a. continue b. break c. exit d. endWhich kind of while loop may be broken by entering a letter or number into the input field? The loop's eof, counter, and flag may all be managed with the help of the loop sentinel.What type of loop, such as counter control or sentinel control, will you use in each of the following situations?a. Sum the following series: 1 + (2 / 1) + (3 / 2) + (4 / 3) + (5 / 4) + ... + (10 / 9)b. Sum the following numbers, except the last number: 17, 32, 62, 48, 58, -1c. A file contains employees’ salary. Update employees’ salary.
- This is a small “holding section” in memory that many systems write data to before writing the data to a file.a. bufferb. variablec. virtual filed. temporary fileHello! I need the PSEUDOCODE(not source code) for this problem please! Just the pseudocode! Thank you for your time and help! Its appreciated! 1. Write a program named filemaker.py that will be used to store the first name and age of some friends in a text file named friends.txt. The program must use a while loop that prompts the user to enter the first name and age of each friend. Each of these entries should be written to its own line in the text file (2 lines of data per friend). The while loop should repeat until the user presses Enter (Return on a Mac) for the name. Then, the file should be closed and a message should be displayed. See Sample Output.SAMPLE OUTPUT Enter first name of friend or Enter to quit DennyEnter age (integer) of this friend 24Enter first name of friend or Enter to quit PennyEnter age (integer) of this friend 28Enter first name of friend or Enter to quit LennyEnter age (integer) of this friend 20Enter first name of friend or Enter to quit JennyEnter age…Which kind of while loop is ended by a character or value entered by the user? While loop eof, loop counter, and loop flag are all under control, and while loop sentinel is also under control
- Hello! I need the PSEUDOCODE(not source code) for this problem please! Just the pseudocode! Thank you for your time and help! Its appreciated! 2. Now write a program named filereader.py that reads and displays the data in friends.txt. This program should also determine and print the average age of the friends on file. That will require an accumulator and a counter. Use a while loop to process the file, print the data, and modify the accumulator and counter. Then close the file and display the average age accurate to one decimal place. See the Sample Output..SAMPLE OUTPUT My friend Denny is 24My friend Penny is 28My friend Lenny is 20My friend Jenny is 24Average age of friends is 24.0Dim inventory As IO.StreamReader is a declaration statement for a procedure-level variable named inventory. The variable will be used to read data from a sequential access file.
