Chapter 8, Problem 4P

Create a new class called Dog that is derived from the Pet class given in Listing 6.1 of Chapter 6. The new class has the additional attributes of breed (type string) and boosterShot (type boolean), which is true if the pet has had its booster shot and false if not. Give your classes a reasonable complement of constructors and accessor methods. Write a driver program to test all your methods, then write a program that reads in five pets of type Dog and displays the name and breed of all dogs that are over two years old and have not had their booster shots.
