Do While Loop

Unlike for and while loops, which test the loop condition at the top of the loop, the do…while loop in C programming language checks its condition at the bottom of the loop.

A do…while loop is similar to a while loop, except that a do…while loop is guaranteed to execute at least one time.

Syntax

do statement while(expression)

The statement is executed and then the expression is evaluated to determine whether or not to execute statement again. The statement will always execute at least once, even if the expression is false when the loop starts

The expected output for this loop is:


Loop iteration 0
Loop iteration 1
Loop iteration 2
Loop iteration 3
Loop iteration 4
