Write a class called CustomerProject

Write a class called CustomerProject. It should have three double fields called hours(the number of hours the project took), materials (the cost of materials) and transportation (transportation costs), in that order. It should have get and set methods for each field. It should have a constructor that takes as parameters the values for each field and calls the set methods to initialize them. It should have a pure virtual function called billAmount that takes no parameters and returns a double.

Write two classes that inherit from CustomerProject: RegularProject and PreferredProject. Both should have a constructor that takes three doubles and passes them to the base class constructor. RegularProject should override billAmount to return the sum of the materials costs, the transportation costs, and $80 times the number of hours. PreferredProject (for preferred customers) should override billAmount to return the sum of 85% of the materials costs, 90% of the transportation costs, and $80 times the number of hours up to a maximum of 100 hours (any hours beyond 100 are free).

Hint: You can access the member data of the base class either of two ways: 1) make that member data protected in the base class, or 2) simply use the get methods, which the derived classes have inherited.

There are no input validation or output formatting requirements.
