C++ Program for Hierarchical Inheritance (Parent → Child1, Child2)

 

✅ C++ Program to Demonstrate Hierarchical Inheritance

#include <iostream>
using namespace std;

class parent {
  public:
    int a, b;
    void data() {
        cout << "Enter two numbers:\n";
        cin >> a >> b;
    }
};

class child1 : public parent {
  public:
    void add() {
        cout << "Addition of " << a << " and " << b << " is " << a+b << "\n";
    }
};

class child2 : public parent {
  public:
    void sub() {
        cout << "Subtraction of " << a << " and " << b << " is " << a-b << "\n";
    }
};

int main() {
    child1 obj1;
    obj1.data();
    obj1.add();

    child2 obj2;
    obj2.data();
    obj2.sub();
}
  

📘 Explanation:

This program demonstrates the concept of hierarchical inheritance in C++. - A single parent class provides the data() function to take input. - Child1 inherits from parent and implements addition. - Child2 inherits from parent and implements subtraction. - Each child class reuses the input method from the parent and performs its own operation.

🧾 Sample Output:

Enter two numbers:
5 3
Addition of 5 and 3 is 8
Enter two numbers:
7 2
Subtraction of 7 and 2 is 5
