How does the while loop relate to its condition?

• A. It runs forever regardless of the condition.
• B. It stops running when the condition is true.
• C. It continues to run while the condition is true.
• D. It requires an else statement to function.

Answer: (C)

The while loop is a fundamental control structure in Python that executes a block of code repeatedly as long as a specified condition evaluates to true. This means that the loop will continue to run and execute its body each time the condition is checked, provided that the condition remains true. In practice, this allows for situations such as iterating over a sequence of numbers, handling user input until a certain criterion is met, or continually checking a condition that might change during the course of the program's execution. For example, if you have a condition checking for a variable that counts down to zero, the while loop will keep executing until that variable is no longer greater than zero, demonstrating its reliance on the truth of the condition to determine whether to loop or stop. The other options do not accurately describe the behavior of a while loop: it doesn't run forever regardless of the condition—unless programmed that way; it stops running when the condition is false, not when it is true; and there is no requirement for an else statement for it to function. The essence of the while loop is to continue execution while the condition holds true, making this the correct understanding of its relationship with the condition.
