While Loop Trouble

[StandardsDT]

I'm having some trouble with my while loop in my code. If I enter in 20 and then enter in 14 for the coupons I want to redeem, it goes into a constant loop and doesn't stop. However I did stop it from doing this by putting in a break; . While this may work it also causes some issues. Some times it runs the whole program properly where the loop will run until it see's that there aren't enough coupons and it tells you that or it will stop and won't get to that point.

How do I fix this? I want the loop to run through and then stop like it should no matter what number I enter. Maybe this is very simple and I'm just not seeing it. But it's 12am here in NJ and I'm beat, it's the one and only thing that's giving me trouble. If that small qwerk get's solved I can turn it in tomorrow :)

Your do...while loop never ends, because endingcoupon is always 1.

You need to reexamine what your process is - I can't really follow what you're trying to do. If you redeem coupons, something has to be reduced so that further looping starts from a lower value.

Thank You. I got the issue solved. You can check it over if you want.
