For this exercise you will extend the StarShip Class created for in class exercise two.

First, you will add a power plant object to the StarShip (details below). This will require additional getters and setters, as well as changes to your constructors.

Next, you will create a derived class IntergalacticStarShip. An IntergalacticStarShip is a StarShip, but with the addition of an auxiliary holidome deck. The auxiliary holidome deck is measured by its available experiences count. The default value of this is 10,000. Remember to make requisite changes to the constructor and display methods

Rebuild your specification, implementation files for StarShip and add specification and implementation files for IntergalacticStarShip. Then, modify your application program (demo) to instantiate objects based on the classes you have developed. Include use of the default and parameterized constructor, getters and setters.

PowerPlant

-type:string

-thrust:double

StarShip

- starShipName : string

-maxVelocity:int

- crewSize : int

- displacement : double

-powerPlant: PowerPlant

IntergalacticStarShip

- starShipName : string

-maxVelocity:int

- crewSize : int

- displacement : double

-powerPlant: PowerPlant

-auxHolidomeExp: int

Include getters and setters, default constructor and parameterized constructor, and a display method.

Use the three file approach, header, implementation and demo.
