c99.h?

[quzah]

No. You have to compile in C99 mode, because the function was introduced then. If you aren't, then your compiler doesn't see it.

If your number is never beyond 9 digits, why are you using long long? It just takes up twice as much space for, in which you will store all zeros (or ones if your number is signed and negative, perhaps). I would suggest using "long" instead of long long. It is fine for up to 9 and a bit digits (that is 9 digits starting with either 1 or 3 in full range of 0..9 on all the other digits).
