3. Structured programming

Create functions for each individual case:

void print_Lazer( Printer* pr /*etc.*/ );

void print_InkjetPrinter( Printer* pr /*etc.*/ );

void print_FaxMachine( Printer* pr /*etc.*/ );

void print( Printer* pr )
{
    if ( pr->type == 'L' ) {
        print_Lazer( Printer* pr /*etc.*/ );

    } else if ( pr->type == 'I' ) {
        print_InkjetPrinter( Printer* pr /*etc.*/ );

    } else if ( pr->type == 'F' ) {
        print_FaxMachine( Printer* pr /*etc.*/ );
    }
}

Problems yet to be solved:

• if-else still remains a complexity!

• boolean flag variables still haunt programmers!

• functions still have too many input parameters!
