Re: do { quit; } else { }

   What do you think of this control block?
    do
   {
      FILE f = fopen("file.txt", "r");
       if (f == NULL) quit; /*goes to else part*/
       /*success here*/
      for (int i =0; i < 10; i++){
          ...
          if (error) quit;
      }
    }
   else
   {
      /*some error*/
   }
