You're assuming he's using a load cell - just one of the many things that he failed to specify!

So, it should be:

void main( void )
{
   initialise_and_set_up_everything();

   display( "Copyright (c) 2007, 8052.COM" );

   for( ;; )
   {
      read_the_weight_sensor(); 
      average_the_readings(); 
      convert_to_units(); 
      display_result(); 
   }
}
