Objectives:
Learn about inheritance
Explore how to redefine the member functions of a base class
Learn about composition/aggregation
Download Lab10.cpp. In this file, the definition of the class personType has given. Think of the personType as the base class.
Question1 (Inheritance)
Derive the class doctorType, inherited from the class personType, with an additional class member variable member to store a doctor’s specialty(string type) Then, implement following class member function prototypes.
doctorType(string,string,string);//Firstname Lastname Specialty doctorType();//Default constructor
void setSpecialty(string);//Set doctor specialty
string getSpecialty()const;// Get doctor specialty
void print()const;//Display doctor information the same as given output format
Derive the class patientType, inherited from the class personType, with additional class member variables to store a patient’s id, age, and dob (all are integers). Then, implement following class member function prototypes.
patientType(string, string, int, int, int);//Firstname Lastname id age dob
patientType();Default constructor
void setId(int);//Set patient id
void setage(int);//Set patient age
void setDob(int);//Set patient DOB
int getId()const;//Get patient id
int getage()const;//Get patient
int getDob()const;//Get patient DOB
void print()const; //Display patient information the same as given output format
Question2 (Composition)
Design a class billType, with class member variables to store a patient’s information (patientType), the patient’s doctor’s information (doctorType), and the hospital charges(double). Then, implement following class member function prototypes.
billType(doctorType &d, patientType &p); // Constructor void setCharge(double);//Set hospital charges double getCharge()const;//Get hospital charges
void print()const;//Display a bill information the same as given output format
Use the provided driver program to test your program. You should get the same output.
Submit a single cpp file.
Output:
Write two programs in one single cpp file.
