In the first case, the X++ operation is completed after the body of the loop, so the initial value of X is run through the loop.
In the second case, the X-- operation is completed before the body of the loop, so the initial value of X is skipped in the loop.
Why?
Is the final expression in the for() loop tied to the {} braces, whereas the loop condition is taking place distinctly before the {} braces?
