What happens when a boolean expression in a while loop evaluates to false?

When a boolean expression in a while loop evaluates to false, the loop terminates. This termination occurs because the while loop is designed to continue executing as long as its associated boolean condition evaluates to true. Once the condition is false, the loop's execution stops, and control is transferred to the next statement following the loop.

This behavior is fundamental to the functioning of while loops in programming. By evaluating the condition initially before the loop's body executes, the language ensures that the loop's code block runs only when the condition is true. Therefore, when the condition changes to false, it signifies that the criteria for continuing the loop have not been met, leading to the cessation of the loop's execution. This mechanism is essential for preventing infinite loops and ensuring that loops can terminate based on the specified logic.
