Answer to Question #290532 in C++ for Hamza Aftab

Question

Create a class named Person, which contains

•A pure virtual function named print()

•Two data fields i.e. personName and age

A class named Patient inherits Person class, which contains

•Two data fields i.e. diseaseType and recommendedMedicine

•Overridden function print() to display all details relevant to a patient

A class named MedicarePatient inherited from class Patient, which holds

•A data field representing the name of the hospital

•A data filed representing the name of the ward

•A data field representing room number

•Overridden function print() to display all details relevant to a patient

In the main function, create instances of derived classes to access respective print() function using dynamic binding.

Answer 1

#include <iostream>
#include <string>




using namespace std;


class Person{
private:
	string personName;
	int age;
public:


	Person(){}


	Person(string personName,int age){
		this->personName=personName;
		this->age=age;
	}


	virtual void print()=0{
		cout<<"Person name: "<<personName<<"\n";
		cout<<"Person age: "<<age<<"\n";
	}
};




//A class named Patient inherits Person class, which contains
class Patient:public Person{
private:
	//Two data fields i.e. diseaseType and recommendedMedicine
	string diseaseType;
	string recommendedMedicine;
public:


	Patient(){}


	Patient(string personName,int age,string diseaseType,string recommendedMedicine):Person(personName,age){
		this->diseaseType=diseaseType;
		this->recommendedMedicine=recommendedMedicine;
	}
	///Overridden function print() to display all details relevant to a patient
	void print(){
		Person::print();
		cout<<"Patient disease type: "<<diseaseType<<"\n";
		cout<<"Patient recommended medicine: "<<recommendedMedicine<<"\n";
	}
};


//A class named MedicarePatient inherited from class Patient, which holds
class MedicarePatient:public Patient{
private:
	//A data field representing the name of the hospital
	string nameHospital;
	//A data filed representing the name of the ward
	string nameWard;
	//A data field representing room number
	int roomNumber;


public:


	MedicarePatient(){}


	MedicarePatient(string personName,int age,string diseaseType,string recommendedMedicine,string nameHospital,string nameWard,int roomNumber):
	Patient(personName,age,diseaseType,recommendedMedicine){
		this->nameHospital=nameHospital;
		this->nameWard=nameWard;
		this->roomNumber=roomNumber;
	}
	//Overridden function print() to display all details relevant to a patient
	void print(){
		Patient::print();
		cout<<"Medicare Patient name hospital: "<<nameHospital<<"\n";
		cout<<"Medicare Patient name ward: "<<nameWard<<"\n";
		cout<<"Medicare Patient room number: "<<roomNumber<<"\n";
	}
};






int main(void){


	//In the main function, create instances of derived classes to access respective print() function using dynamic binding.
	Person** person=new Person*[2];
	person[0]= new Patient("Peter",25,"disease type 1","Recommended medicine 1");
	person[1]= new MedicarePatient("Mike",45,"disease type 2","Recommended medicine 2","name Hospital","nameWard 45",5);


	for(int i=0;i<2;i++){
		person[i]->print();
	}


	system("pause");
	return 0;
}
