Question

In this project, you will design various classes and write a program to computerize the billing system of a hospital.

a. Design the class doctorType, inherited from the class personType, defined in Chapter 10, with an additional data member to store a doctor’s speciality. Here is the UML diagram for this class:

b.    Design the class billType with data members to store a patient’s ID and a patient’s hospital charges, such as pharmacy charges for medicine, doctor’s fee, and room charges. Add appropriate constructors and member functions to initialize, access, and manipulate the data members. Here is the UML diagram for this class:

c. Design the class patientType, inherited from the class personType, defined in Chapter 10, with additional data members to store a patient’s ID, age, date of birth, attending physician’s name, the date when the patient was admitted in the hospital, and the date when the patient was discharged from the hospital. (Use the class dateType to store the date of birth, admit date, discharge date, and the class doctorType to store the attending physician’s name.) Add appropriate constructors and member functions to initialize, access, and manipulate the data members. Here is the UML diagram for this class:

Write a program to test your classes:

Create a patientType object and a billType object for that patient using the constructors and passing parameters with initial values to them.. Use the print functions from both objects to display the patient's information and charges.

Create a different patientType object using the default constructor. Use the setter and getter member functions to set and display the patient's information.

Create a third patientType object using the constructor with parameters, but pass it a bad date.

Here is an example of what the output should look like:

Turn in all your .h files, all your implementation files, and your test program. Make sure your header files are properly documented. Also turn in one or more screen shots showing the results of your testing.

Once this project is completed, you will demonstrate that you can

Utilize inheritance and composition in designing classes

Utilize polymorphism by overriding base class functions

Distinguish between accessing the members of a derived class from accessing the members of an aggregate class

Distinguish between applying the constructor for a derived class and applying the constructor of an aggregate class
