The trident in AC Milan is the core of the team, while other team members are just a processor player. So you can use the trident as a Facade. The advantage is to block other members of the customer (coach), reduce the number of objects treated by the customer (coach) and make the subsystem more convenient; realize the loose coupling relationship between the subsystem and the customer (coach), while the player It is tight; if necessary, the customer (coach) is not hindered by other players, so you can choose between the system (team) ease of use and universal. The code is as follows: Class Other players {public: other players (); virtual ~ other players ();
Class trident {public: trident (); Virtual Void contact ();
Void Trident :: Contact () {Other players ();
