The following is a specification of three classes:

Class Vehicle:

Attributes:

Age, an integer -> The age of the vehicle

Price, a float -> The first name of the vehicle

Behaviors:

Vehicle() -> default constructor sets age=0, and price=0.0

setAge() -> Takes an integer parameter, returns nothing

setPrice() -> Takes a float parameter, returns nothing

getAge() -> Takes no parameters, returns the vehicles age

getPrice() -> Takes no parameters, returns the vehicles price

End Class Vehicle

Class Car:

Attributes:

An object of type Car has all the attributes of an

object of type Vehicle

Additionally, Cars have attributes that Vehicles do not:

RaceCarStatus, a boolean -> yes or no

Behaviors:

An object of type Car has all the behaviors of an object of

type Vehicle

Additionally, Cars have behaviors that Vehicles do not:

Car() -> default constructor sets RaceCarStatus=false

setRaceCarStatus() -> Takes an boolean parameter, returns nothing

getRaceCarStatus() -> Takes no parameters, returns the cars race car status

End Class Car

Class Truck:

Attributes:

An object of type Truck has all the attributes of an

object of type Vehicle

Additionally, Trucks have attributes that Vehicles do not:

DieselTypeStatus, a boolean -> yes or no

Behaviors:

An object of type Truck has all the behaviors of an object of

type Vehicle

Additionally, Cars have behaviors that Vehicles do not:

Truck() -> default constructor sets DieselTypeStatus=false

setDieselTypeStatus() -> Takes a boolean parameter, returns nothing

getDieselTypeStatus() -> Takes no parameters, returns the Trucks diesel type status

End Class Truck

It would be a horrible waste of valuable programming time to redefine all of the functions in Car or Truck when many of them are already defined. This assignment is to reinforce the application of inheritance.

Requirements:

1.) Draw three UML class diagrams, one for each of the classes mentioned above

2.) Draw a generalization among the three class diagrams, showing the inheritance relationship.

3.) Implement the three classes described earlier (Vehicle, Car and Truck) and write a driver function (main) in order to test them. For the testing, write the following test code in your main( ) :

Vehicle x;

cout << Initial value for x: << endl;

cout << Age = << x.getAge() << Price= << x.getPrice() << endl;

x.setAge(40);

x.setPrice(20000);

cout << Modified value for x: << endl;

cout << Age = << x.getAge() << Price= << x.getPrice() << endl;

repeat the above steps for Car y; and Truck z; . Note that additional behaviors in class Car and Truck should also be tested.

Display the results in tabular format (one is already done for you) as follows:

Value used for test, and what function(s)	Reason for Test	Expected Result	Actual Result
setAge( 15 )	To ensure that the age is setting the value properly, and that getAge( ) is returning	After setAge(15) is called, getAge() should return 15.	After using cout<< on the member function getAge(), 15 was printed.
