There's a potential memory leak on the highlighted line (if you exit on Nth allocation, you never free the N-1 allocated memory before that).

Also, this fizzbuzz has a O(n*m) complexity, which is fucking ridiculous.

And thirdly, you use scanf to read into a buffer on the stack, not checking the length, which is a potential buffer overflow.

You're really bad at C, malpa.
