Thread: Calling a function...

Code:

int main()
{
   char weight[6];
   int validity, break_flag;

   while(1)
   {
      break_flag = getinput (weight);
      if (break_flag == 1)
         break;
      validity = validate(weight);
      if (validity == 1)
         printf("%s - Too Heavy\n", weight);
      else
         printf("%s - Cleared\n", weight);
   }
   return 0;
}

I have the following code as my main function but I have just been told I'm not allowed to have a loop in my main. I tried moving the while loop to new function and using main to call that function (as below) but got the following errors:

weight.c: In function `loop':
weight.c:111: warning: control reaches end of non-void function
weight.c: In function `main':
weight.c:115: warning: statement with no effect

The program works fine before the changes.

Code:

int loop()
{
   char weight[6];
   int validity, break_flag;

   while(1)
   {
      break_flag = getinput (weight);
      if (break_flag == 1)
         break;
      validity = validate(weight);
      if (validity == 1)
         printf("%s - Too Heavy\n", weight);
      else
         printf("%s - Cleared\n", weight);
   }
}

int main()
{
   loop;

   return 0;
}

According to my teacher it is a programming rule.

Thanks for your help.

I guess it will just be a rule to pass the subject then I'll forget about it in that case lol
