breaking out of program

In regards to the default case, i need the prog to only end if there is no input. If i put return 0; the prog ends only after one loop, and if i put break; the prog never ends.

Can anyone tell me how i fix this?

Code:

---

  int main(){
         
 
      while ( fgets( buff, BUFSIZ, stdin ) != NULL ) {
        switch ( buff[0] ) {
            case '0':
              one (buff);
              break;
            case '1':
              one (buff);
              break;
            case '2':
              one (buff);
              break;
            case '3':
              one (buff);
              break;
            case '4':
              one (buff);
              break;
       
            case '5':
              one (buff);
              break;
       
            case '6':
              one (buff);
              break;
       
            case '7':
              one (buff);
              break;
       
            case '8':
              one (buff);
              break;
       
            case '9':
              one (buff);
              break;
       
            default:
              two(buff);
              return 0;
        }
      }
  }

Code:

---

  int main(){
      int quit = 0;
         
 
      while ( !quit && fgets( buff, BUFSIZ, stdin ) != NULL ) {
        switch ( buff[0] ) {
            case '0':
              one (buff);
              break;
            default:
              two(buff);
              quit = 1;
        }
      }
  }

I'm still relatively new to C programming, although I completed a university course in programming with C. ^^; Haven't had much practice since then. :p

Anyway, my question is, is it unprofessional to use a Go to statement in a case like this?

Not as long as you can defend your choice of using goto to every yahoo who reads your code. :rolleyes:
