Single Inheritance Example in C++

---

This code defines two classes Base and Derived where Derived is derived from Base class publicly. The Base class has an integer data member a and a member function display() which displays the value of a. The Derived class has a member function show() which displays the message "Show of Derived".

In the main function, an object of Derived class is created named d. The integer data member a of Base class is assigned a value of 100. The display() function of Base class is called using the d object which displays the value of a. The show() function of Derived class is called using the d object which displays the message "Show of Derived".

Source Code

#include <iostream>
using namespace std;
class Base
{
public:
    int a;
    void display()
    {
        cout<<"Display of Base "<<a<<endl;
    }
};
class Derived:public Base
{
public:
    void show()
    {
        cout<<"Show of Derived"<<endl;
    }
};
int main()
{
    Derived d;
    d.a=100;
    d.display();
    d.show();
}
