C++ Program for Multi-Level Inheritance (Grandparent → Parent → Child)

✅ C++ Program to Demonstrate Multi-Level Inheritance

#include <iostream>
using namespace std;

class grandparent {
  public:
    void display1() {
        cout << "Hello I am your grandparent:\n";
    }
};

class parent : public grandparent {
  public:
    void display2() {
        cout << "Hello I am parent:\n";
    }
};

class child : public parent {
  public:
    void display3() {
        cout << "Hello I am child:\n";
    }
};

int main() {
    child obj;
    obj.display1();
    obj.display2();
    obj.display3();
}
  

📘 Explanation:

This program demonstrates the concept of multi-level inheritance in C++. - The grandparent class defines display1(). - The parent class inherits from grandparent and adds display2(). - The child class inherits from parent and adds display3(). - Thus, an object of the child class can access functions from all three classes.

🧾 Sample Output:

Hello I am your grandparent:
Hello I am parent:
Hello I am child:

This C++ program demonstrates multi-level inheritance where a child class inherits from a parent, which in turn inherits from a grandparent class. Includes example code, explanation, and sample output.
