c is double, thus you cannot use the modulo operator %. Use fmod() instead. So change this: to this: As Slava mentioned, you could have used an int instead, like this: which wouldn’t require the use of fmod().

After all, if such recursive containment were allowed, … Read more
Here is a (maybe less verbose) way to split string (based on the post you mentioned).
