In looping constructs, what function does the condition serve?

The condition in looping constructs plays a critical role in controlling the flow of the loop. Specifically, it evaluates whether the loop should continue to execute or terminate. When a loop is initiated, the condition is checked before each iteration; if the condition evaluates to true, the loop's body is executed. Conversely, when the condition evaluates to false, the loop stops running, and control moves to the next statement following the loop.

This mechanism is essential in preventing infinite loops, ensuring that the loop only runs a specific number of times or continues until a particular state is achieved. For instance, in a while loop, the condition is evaluated at the beginning of each iteration. Similarly, in a for loop, the condition is checked after the initialization and before each subsequent iteration.

Understanding the purpose of the condition helps in designing efficient and effective looping constructs that correctly implement the desired logic in programming.
