Why while loop in c

Types of Loops in C Depending upon the position of a control statement in a program, looping statement in C is classified into two types: 1. Entry controlled loop 2. Exit controlled loop In an entry control loop in C, a condition is checked before executing the body of a loop.

Loop Type Description 1. While Loop In while loop, a condition is evaluated before processing a body of the loop. Do-While Loop In a do…while loop, the condition is always executed after the body of a loop. For Loop In a for loop, the initial value is performed only once, then the condition tests and compares the counter to a fixed value after each iteration, stopping the for loop when false is returned.

If testExpression is false , the loop terminates ends. Hence, the body of the while loop is executed. This prints 1 on the screen and the value of i is increased to 2. The body of the while loop is executed again. This prints 2 on the screen and the value of i is increased to 3. This process goes on until i becomes 6.
