Virtual Function Example in C++

.cpp

#include <iostream>
using namespace std;

class Parent{
    public:
        virtual void print(){
            cout<<"PARENT PRINT"<<endl;
        }
        void display(){
            cout<<"PARENT DISPLAY"<<endl;
        }
};

class Child:public Parent{
    public:
        void print(){
            cout<<"CHILD PRINT"<<endl;
        }
        void display(){
            cout<<"CHILD DISPLAY"<<endl;
        }
}

int main(){
    Parent *p;
    Child c;
    p = &c;
    
    p->print();   // VIRTUAL
    p->display(); // NON-VIRTUAL

    // "CHILD PRINT"
    // "PARENT DISPLAY"
