Answer to Question #292899 in C++ for Neha Das

Question

Create the Person class. Create some objects of this class (by taking information from the

user). Inherit the class Person to create two classes Teacher and Student class. Maintain the

respective information in the classes and create, display and delete objects of these two classes

(Use Runtime Polymorphism).

Answer 1

#include <iostream>
#include <string>
using namespace std;


//Create the Person class.
class Person  
{
private:
	string name;
	int age;
public:
	Person(){}


	virtual void get(){
		cout<<"Enter the person name: ";
		getline(cin,name);
		cout<<"Enter the person age: ";
		cin>>age;
	}
	virtual void display(){
		cout<<"The person name: "<<name<<"\n";
		cout<<"The person age: "<<age<<"\n";
	}
};


class Teacher:public Person{


private:
	float salary;
public:
	Teacher(){}
	virtual void get(){
		Person::get();
		cout<<"Enter the teacher salary: ";
		cin>>salary;
	}
	virtual void display(){
		Person::display();
		cout<<"The teacher salary: "<<salary<<"\n";
	}
};


class Student:public Person{


private:
	string grade;
public:
	Student (){}
	virtual void get(){
		Person::get();
		cout<<"Enter the student grade: ";
		cin>>grade;
	}
	virtual void display(){
		Person::display();
		cout<<"The student grade:: "<<grade<<"\n";
	}
};




int main(){
	Person* persons[2];


	Teacher* teacher=new Teacher();
	teacher->get();
	cout<<"\n";
	fflush(stdin);
	Student* student=new Student();
	student->get();


	persons[0]= teacher;
	persons[1]= student;
	cout<<"\n";
	for(int i=0;i<2;i++){
		//display the information about the persons using Polymorphism
		persons[i]->display();	
		cout<<"\n";
		delete persons[i];
	}


	system("pause");
	return 0;
}
