two different command line argument in c

i want to parse two different command line argument such that :

file -f something -o something

i found some code on internet and i changed it but i cannot parse both of them. 

int
main (int argc, char **argv)
{
  char *fvalue = NULL;
  char *ovalue = NULL;
  int index;
  int c;

  opterr = 0;
  while ((c = getopt (argc, argv, "fo:")) != -1)
    switch (c)
      {
      case 'f':
        fvalue = optarg;
        break;
      case 'o':
        ovalue = optarg;
        break;
      default:
        abort ();
      }
  printf ("fvalue = %s, ovalue = %s\n",
          fvalue, ovalue);

  for (index = optind; index < argc; index++)
    printf ("Non-option argument %s\n", argv[index]);
  return 0;
}

Your optstring is wrong, it must be

while ((c = getopt (argc, argv, "f:o:")) != -1)

the colon means that the option requires an argument.
