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

Short Answer

Expert verified

Answer: A while loop tests its condition before performing an iteration.

Step by step solution

Understanding a While Loop

A while loop is a type of loop that continues to execute a block of code as long as the specified condition evaluates to true. The general syntax for a while loop is: ``` while (condition) { // code to be executed } ```

Execution Order of a While Loop

The execution order of a while loop starts with checking the condition. If the condition in the loop is true, then the loop will proceed with executing the code within it. Once the code in the loop is executed, the condition is checked again, and this process repeats until the condition evaluates to false. In other words, the while loop tests its condition before it performs an iteration.

Example

Here's a simple example of a while loop: ``` int counter = 0; while (counter < 5) { // Code to be executed counter++; } ``` In this example, the while loop will first check if `counter` is less than 5. If it is, then the loop will execute the code inside it, incrementing the counter by 1. After that, the condition is checked again. This process repeats until the condition is false (i.e., when the counter is no longer less than 5).
