Solution in C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <stdio.h>

int main()
{
  int num, i;
  int tmp[3];
  char output[6] = "ABC";

  scanf("%d", &num);

  tmp[0] = num / 100;
  num %= 100;
  tmp[1] = num / 10;
  num %= 10;
  tmp[2] = num;

  for(i = 3; i < 6; i++){
    output[i] = tmp[i-3] + '0';
  }

  //printf("%s\n", output);

  return 0;
}
