Design pattern C + + implementation six: Prototype mode

Prototype mode (PROTOTYPE): Specifies the kind of object created with the prototype instance, and creates a new object by copying the prototypes. The prototype pattern is actually creating another customizable object from one object without needing to know the specifics of the creation.
