                    In this post, we will see C++ Class, Object, Constructor, Destructor, Data Members and Member Functions | All in One Video 

Program Code: (classexample.cpp)

#include<iostream>

using namespace std;

class Sample

{

    private:

    int a,b;

    

    public:

    Sample()  //default constructor

    {

        a=4;

        b=9;

        cout<<"Inside default constructor"<<endl;

    }

    Sample(int x,int y)  //parameterized constructor

    {

        a=x;

        b=y;

        cout<<"Inside parameterized constructor"<<endl;

    }

    ~Sample()  //destructor

    {

        cout<<"Inside destructor"<<endl;

    }

    

    void getdata()

    {

    cout<<"Enter first number"<<endl;

    cin>>a;

    cout<<"Enter second number"<<endl;

    cin>>b;

    }

    void showdata()

    {

    cout<<"Value of a="<<a<<endl;

    cout<<"Value of b="<<b<<endl;

    }

    

};

int main()

{
