Thread: do while loop keeps looping

...
digit != '\0' = 1 != 0 = 1
so we go on to the next iteration. In the next iteration,
removed = number2 / 20 = 10 / 10 = 1.
digit = removed % 10 = 1 % 10 = 1
At this point we can easily conclude that since number2 is never changed, the loop will loop infinitely.

Ah I see. That was really stupid of me. So basically I need to give number2 the removed value so it keeps going down by 1 digit each time. Let me give this a shot, thanks laserlight

Got it working. I just used this:

Code:

number2 = number2/10;
etc

Everything is working awesome, only problem is that i get a zero at the end. for example:
1
x 1234
--------
4
3
2
1
0

Would there be a more efficient way to loop this so that I dont always get a zero at the end?
