C++ Program to Demonstrate Function Overloading

✅ C++ Program to Demonstrate Function Overloading Using Addition

#include <iostream>
using namespace std;

class maths
{
public:
    int add(int x, int y)
    {
        return x + y;
    }

    int add(int x, int y, int z)
    {
        return x + y + z;
    }
};

int main()
{
    int a, b, c;
    maths m;   // object of class

    cout << "Enter any two numbers:" << endl;
    cin >> a >> b;
    cout << "Sum of two numbers is: " << m.add(a, b) << endl;

    cout << "Enter any three numbers:" << endl;
    cin >> a >> b >> c;
    cout << "Sum of three numbers is: " << m.add(a, b, c) << endl;

    return 0;
}
  

📘 Explanation:

This program demonstrates function overloading in C++, which is a feature of compile-time polymorphism.

• add(int x, int y) — adds two integers.
• add(int x, int y, int z) — adds three integers.

Both functions have the same name but different parameter lists. The compiler decides which function to call based on the number of arguments passed.

🧾 Sample Output:

Enter any two numbers:
10 20
Sum of two numbers is: 30
Enter any three numbers:
1 2 3
Sum of three numbers is: 6
