Question

Does the while loop test its condition before or after it performs an iteration?

Short answer

Explain the behavior of a while loop. Answer: The condition of a while loop is tested before each iteration during its execution. A while loop allows a set of statements to be executed repeatedly as long as its specific condition remains true. If the condition is true, the loop executes the statements inside it and then tests the condition again. If the condition is false, the loop terminates, and the program continues with the code following the loop.

Step-by-step solution

Understanding While Loops

A while loop is a control structure that allows a set of statements to be executed repeatedly as long as a specific condition remains true. It is essential to note that the condition is tested before each iteration of the loop. If the condition is false at the beginning, the loop will not execute.

Testing Condition in While Loop

The while loop tests its condition before it performs an iteration. If the condition is true, the loop executes the statements inside it and then tests the condition again. If the condition is false, the loop terminates, and the program continues with the code following the loop.
