Answer 1

you can make it this way also......

  char str[30];
  scanf("%s",str);
  char c[30];
  int i, num, denom;

  i = 0;
  while (*(str+i) != '/')
  {
      memcpy((c+i), (str+i), 1);
      i++;
  }
  *(c+i) = 0;
  i++;
  num = atoi(c);
  strcpy(c, (str+i));
  denom = atoi(c);
  printf("%d\n", num);
  printf("%d\n", denom);
