Types of Loop
Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.
Loops
Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.
While Loop
Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.

- 4. What will be the value of x after the following loop is executed? X = 0 For i = 1 To 2 For j = 1 To 3 x=x*i+j Next j Next i6. If there is a cycle: for ( int i=0; i<=5;i++) { i++; } How many times will the loop body be executed? А. О B. 3 times C. 5 times D. 6 timesYou need to write a loop that will repeat exactly 125 times. Which is the preferred loop construct to use? A. while B. do while loop C. for loop
- What is the number of times the following loop is executed? for an in the range(100,10,-10): a = 100,10,-10 create a printoutWe use For loop instead of a while loop when we know exactly how many times you want to loop through a block of code. True FalseWhat will this For loop will print on the screen? FOR x = 1 TO 5 Print x * x Next x
- Create a class name AddAgain for do-while loop that asks the user to enter two The numbers should be added and the sum displayed. The loop should ask the user whether he or she wishes to perform the operation again. If so, the loop should repeat; otherwise it should terminate.This test can only be taken once.

O while loop checks the condition before the loop begins, whereas the do-while loop executes the body at least once before checking the condition. O while loop is used for counter-controlled and do-while, is used for a sentinel loop. O while loop is used for selection controlled and do-while is used for an infinite loop. O while loop is used for endless controlled control and do-while, is used for counter-controlled loop. Save All Ans Click Save and Submit to save and submit.

- Basic while loop expression. Write a while loop that prints userNum divided by 4 (integer division) until reaching 2 or less. Follow each number by a space. Example output for userNum = 160:40 10 2 Note: These activities may test code with different test values. This activity will perform four tests, with userNum = 160, then with userNum = 8, then with userNum = 0, then with userNum = -1. See "How to Use zyBooks".Also note: If the submitted code has an infinite loop, the system will stop running the code after a few seconds, and report "Program end never reached." The system doesn't print the test case that caused the reported message.Part A: While Loop Program - using Java. Write a program that detects Fibonacci numbers. Prompt the user to input a positive integer. Upon input, the program will determine if the number is either a Fibonacci number or not. If a Fibonacci number, then the order of the number in the sequence must be output. If not a Fibonacci number, then the Fibonacci numbers above and below it (including their order in the sequence) must be output. Once it finishes, the program will prompt the user for a new number. The program will exit if the user enters a non-integer number or string (such as “quit”) instead of an integer. Use the sample output file, fib-seq-det.txt, to view a sample session Additionally: For both the above problems, the first four numbers of the Fibonacci sequence are: 0, 1, 1, and 2. Part A must use While loops onlyIf a loop does not contain within itself a way to terminate, it is called a: Select one: a. infinite loop b. do-while loop c. while loop d. for loop
