Brief Explanations:

In programming, a while loop continues executing as long as a given condition (an expression with a true - or - false value) is true. A for loop has a more structured setup for initialization, condition, and increment/decrement. There is no such thing as a "last variable loop" or "break loop" in standard programming concepts. The key here is that the while loop's operation depends on a true/false condition.
