Exercise L1-2 Chapter 11 Inheritance & CompositionThis exercise is designed so each patient can have multiple doctors, and multiple bills. The details are listed below:Design the class doctorType, inherited from the class personType, given below. Add a data member to storethe doctors specialty. Also add appropriate constructors and member functions to initialize, access, andmanipulate the data members.A.#pragma once#include using namespace std;class personType{public:void print() const;//Function to output the first name and last name//in the form firstName lastName.}void setName(string first, string last);//Function to set firstName and lastName according//to the parameters.//Postcondition: firstName = first; lastName = laststring getFirstName() const;//Function to return the first name.//Postcondition: The value of the data member firstName11is returned.}string getLastName() const;//Function to return the last name.//Postcondition: The value of the data member lastNameis returned.personType(string first = **, string last = "");//constructorprivate:string firstName; //variable to store the first namestring lastName; //variable to store the last name//Sets firstName and lastName according to the parameters.//The default values of the parameters are empty strings.//Postcondition: firstName = first; lastName = last};void personType::print() const{}void personType::setName(string first, string last){cout <<< firstName << " " << lastName;firstName= first;lastName = last;string personType::getFirstName() constreturn firstName;string personType::getLastName() const{return lastName;}//constructorpersonType: :personType(string first, string last) B.C.D.{firstName = first;lastName = last;}Designed the class billType with data members to store a patients ID and a patient's hospital charges, suchas pharmacy charges for medicine, Doctors fee, and room charges. Add appropriate constructors and memberfunctions to initialize, access, and manipulate the data members.Design the class patientType, inherited from the class personType, with additional data members tostore the patients ID, the age, date of birth, attending Physicians name, the date when the patient wasadmitted in the hospital, and the date when the patient was discharged from the hospital. (use the classdateType to store the date of birth, admit date, discharge date, and the class doctorType to store to beattending Physicians name.) Add appropriate constructors and member functions to initialize, access, andmanipulate the data members.Write a program to test your classes. You can check your class definitions by using L1-2CmplTest.cpp found inthe L1-2 folder.Your output should look like thisG:\Coursework\CIS 23 - Data Structures and Algorithme Solutions Lab1\L1-2\Debug>L1-2.exeJohn UrrutiaL1-2L1-2.exeEnter patient's ID: 123456Enter patient's first name: JoeEnter patient's last name: BlowinskiEnter doctor's first name: RobEnter doctor's last name: UblindEnter doctor's speciality: PaychiatryPatient: Joe BlowinskiAttending Physician: Rob Ublind PaychiatryAdmit Date: 4-15-2009Discharge Date: 4-21-2009Pharmacy Charges: $245.50Room Charges: $2500.00Doctor's Fees: $3500.38Total Chargee: $6245.88Press any key to continue...Class membersdoctorType Class must contain at least these functionsdoctorType(string first, string last, string spl); //First Name, Last Name, Specialty
