Thread: Doubt!!!

could somebody please explain how this works (Dos based):

Code:

   int main( void)

    {

       int i ;

      char ch ;  

      scanf("%d", &i);
      scanf("%c", &ch);
    
      if ( ch != 10)
         printf( "Error ");
      else
         printf (" %d ", i);
   }

why is ch compared to 10 ?
....
this gives "error" when i input a character instead of an integer.

does the value 10 have anything to do with the ascii codes ????

thanks a lot.....
