1. C++ and OO design

• Consider:

  
  void print( Printer* pr )
  {
      if ( pr->type == 'L' ) {
          // compose and send print job to lazer printer
  
      } else if ( pr->type == 'I' ) {
          // compose and send print job to ink-jet printer
  
      } else if ( pr->type == 'F' ) {
          // compose and send fax
      }
  }
