C++ - how to find the length of an integer

Question

I\'m trying to find a way to find the length of an integer (number of digits) and then place it in an integer array. The assignment also calls for doing this without the use

If you can use C libraries then one method would be to use sprintf, e.g.

#include <cstdio>

char s[32];

int len = sprintf(s, "%d", i);
