Question

In C++, design a class named "Ship" that keeps the following information:

• Registry (which country the ship is registered in)
• Homeport (where the ship normally is when not underway)
• Name (the ship's name)
• Length (in feet)
• Displacement (in tons. Displacement is a measure of how large the ship is)

Write a default constructor as well as a constructor that takes all five arguments. Write appropriate accessor and mutator functions for the class.

Next, write a class named "Ferry" that is derived from the "Ship" class. The "Ferry" class should have member variables that hold the following information:

• Passenger capacity
• Car capacity
• Origin (meaning the city in which the ferry normally starts service)
• Destination (the city where the ferry travels to)
• Ticket price

Write a default constructor as well as a constructor that takes all *ten* arguments (five from the Ferry class, and five from the Ship class), making sure to properly pass some of those arguments to the function call for the base class constructor.

Next, write a class named "NavyShip" that is also derived from the "Ship" class. The "NavyShip" class should have member variables holding the following information:

• Ship type (e.g. destroyer, frigate, battleship, minesweeper)
• Ship designation (e.g. DD-423)
• Number of crewmembers
• If it is nuclear-powered or not
• Maximum speed

Just as with the "Ferry" class, write a default constructor as well as a constructor that takes all ten arguments, properly passing the necessary arguments to a function call to the base class constructor.

Demonstrate the classes by writing a program that creates two arrays: one of Ferry objects and one of NavyShip objects. Have each array contain just two objects. Use the data shown below, in the output, to populate your object data.

Sample output is below. Meet this minimum level of output formatting, or improve on it (impress me!). This output also gives you the data necessary to load into your various objects:

Information for the Ferry Walla Walla:
        > Registry: US
        > Homeport: Seattle
        > Length: 440
        > Displacement: 4860
        > Passenger Capacity: 2000
        > Car Capacity: 188
        > Origin: Edmonds
        > Destination: Kingston
        > Ticket Price: 35.95

Information for the Ferry Samish:
        > Registry: US
        > Homeport: Seattle
        > Length: 362
        > Displacement: 4320
        > Passenger Capacity: 1500
        > Car Capacity: 144
        > Origin: Anacortes
        > Destination: Friday Harbor
        > Ticket Price: 45.95

Information for the Navy Ship USS John McCain:
        > Registry: US
        > Homeport: Yokosuka
        > Length: 505
        > Displacement: 8900
        > Type: Destroyer
        > Designation: DDG-56
        > Crew: 281
        > Nuclear: No
        > Max Speed: 35

Information for the Navy Ship USS Ronald Reagan:
        > Registry: US
        > Homeport: Yokosuka
        > Length: 1092
        > Displacement: 101400
        > Type: Aircraft Carrier
        > Designation: CVN-76
        > Crew: 3532
        > Nuclear: Yes
        > Max Speed: 40
