12. Ship, CruiseShip, and CargoShip Classes Design a Ship class that has the following members: • A member variable for the name of the ship (a string) • A member variable for the year that the ship was built (a string) • A constructor and appropriate accessors and mutators • A virtual print function that displays the ship's name and the year it was built. Design a CruiseShip class that is derived from the Ship class. The CruiseShip class should have the following members: • A member variable for the maximum number of passengers (an int) A constructor and appropriate accessors and mutators A print function that overrides the print function in the base class. The CruiseShip class's print function should display only the ship's name and the maximum number of passengers. Design a CargoShip class that is derived from the Ship class. The CargoShip class should have the following members: • A member variable for the cargo capacity in tonnage (an int) • A constructor and appropriate accessors and mutators • A print function that overrides the print function in the base class. The CargoShip class's print function should display only the ship's name and the ship's cargo capacity.
