Need assistance to get started

I have been racking my brain on trying to finish this homework.
I am getting an error right where I start my FOR loop. (subscript requires array or pointer type)

I don't know what I am doing wrong, I modified a working code and added my code to it, but I can't compile it. Anyone please help!!

thanks!

Code:

---

{
  struct felix
  {
  int empno;
  float wages;
  };
  felix record;
  int i;
  FILE *main_file;
  main_file = fopen("master_f", "wb");
  fprintf(stdout, "Enter employee numbers and wages: \n");
  fprintf(stdout, "When done, enter a zero twice \n");
  fscanf(stdin, " %s %f", &record.empno, &record.wages);//Stdin is the file pointer
  for(i = 0; record.empno[0] != '0'; ++i)
  {
      fprintf(main_file, " %s %f \n", record.empno, record.wages);//Write to the file
      fscanf(stdin, " %s %f", &record.empno, &record.wages);
  }
  fclose(main_file);//This should be last pertaining to file open and close.
  fprintf(stdout, "There were %d records entered\n", i);
}

You declared empno as an int, is that what you wanted? If so, why do you use %s and [0]? Either change empno to be a string, or change your code to treat it like an int.

>FILE *main_file;
Why not fstreams?

>fprintf(stdout, <snip>
You could just use printf, it prints to stdout without your having to specify it.

>fscanf(stdin, <snip>
Ditto. scanf is equivalent to fscanf(stdin, ..., ...).

>fclose(main_file);
This wouldn't be needed if you used fstreams. ;)
