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 ships 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 classs print function should display only the ships 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 classs print function should display only the ships name and the ships cargo capacity.

Demonstrate the classes in a program that has an array of three Ship pointers. The array elements should be initialized with the addresses of dynamically allocated Ship, CruiseShip, and CargoShip objects. The program should then step through the array, calling each objects virtual print function.

You MUST document your code with comments!

You MUST submit the following files:

FinalExam.cpp contains the main function

ShipClass.h contains the Ship class implemented with in-line functions

CargoShip.h - contains the Cago Ship class implemented with in-line functions

CruiseShip.h - contains the Cruise Ship class implemented with in-line functions

Example output:

Name: Lolipop Year built: 1960 ---------------------------- Name: Disney Magic Maximum passengers: 2400 ---------------------------- Name: Black Pearl Cargo capacity: 50000 tons ---------------------------- Press any key to continue . . .
