Question

Create a class called FitnessMember that has only one variable, called name. The person class should have a constructor with no parameters, a constructor with a parameter, a mutator function and an accessor function. Also, include a function to display the name. Define a class called Athlete which is derived from FitnessMember. An Athlete record has the Athlete's name (defined in the FitnessMember class) and ID number of type String. Define a class called Trainer whose objects are records for a fitness centers trainers. Derive this class from the class FitnessMember. A Trainer record has the Trainer's name (defined in the FitnessMember class) and a specialty as a String (for example, Weight, Aquatics, Cardio, Nutrition, etc.), and an training session fee (use the type double). A Billing object will contain an Athlete object and a Trainer object. Give all your classes a reasonable complement of constructors, and accessor and mutator functions. Write a main test program that creates at least two Athletes, at least two Trainers, and at least two Billing records and displays the total income from the Billing records. Your tests should test all the functions and constructors defined in your program. Your PDF file should clearly indicate what you are testing and the output.
