There is also an abstract factory pattern
int _tmain (int argc, _tchar* argv[])
{

pizzastore* Nystore = new Nypizzastore ();
pizzastore* Chicagostore = new Chicagopizzastore ();

pizza* Pizza = Nystore->orderpizza ("cheese");
cout<< "Ethan ordered a" <<pizza->getname () <<endl;

Pizza = Chicagostore->orderpizza ("cheese");
cout<< "Joel ordered a" <<pizza->getname () <<endl;
return 0;
}
