Question

• Divide by classes.
• Parameters and return types of each function and class member function should be decided in advance.

Write a program that computes a patient's bill for a hospital stay. The different components are:

• PatientAccount Class
• Surgery Class
• Pharmacy Class
• main program

Patient Account will keep total of the patient's charges. Keep track of the number of days spent in the hospital. Group must decide on hospital's daily rate.

Surgery class will have stored within it the charges for at least five types of surgery. It an update the charges variable of the PatientAccount class.

Pharmacy class will have stored within it the price of at least five types of medication. It can update the charges variable of the PatientAccount class.

Student who designs main will design a menu that allows user to enter a type of surgery and type of medication and check the patient out of the hospital. When patient checks out, the total charges should be displayed.
