Demonstrate the classes in a program that has an array of Ship pointers. The array ele- ments should be initialized with the addresses of dynamically allocated Ship, CruiseShip, and CargoShip objects. (See Program 15-14, lines 17 through 22, for an example of how o do this.) The program should then step through the array, calling each object's print unction. ure et n DU class should
