#include<iostream>
using namespace std;

class Base{
    public:
        Base(){
            cout<<"Base Constructor"<<endl;
        }
        virtual~Base(){
            cout<<"Base Destructor"<<endl;
        }
};

class Derived : public Base{
    public:
        Derived(){
            cout<<"Derived Constructor"<<endl;
        }
        ~Derived(){
            cout<<"Derived Destructor"<<endl;
        }
};
int main()
{
    Base b;
    Base *p = new Derived;
    delete p;
    return 0;
}
