C++ Help, Please. Thank You.

The question is whether evaluating a bool function (for true or false) is the same as "calling" the function and executing the internal code of the function which is conditional on it being true or false. And the answer I am getting is that this is not the same, because my program runs and works.

This code only "calls" passLength IF passLength is false.

Code:

if	(!passLength(password))
	(passLength(password));

If it is false, this gives it another chance to be true. Repeat.

Unlike the solutions graciously suggested by Pete Zicato and Happy Monkey, in my code I do not require a superfluous bool variable. I use the bool function to evaluate itself. Maybe this is "wrong" but it works.
