C++ Program for Function Overloading Example

✅ C++ Program Demonstrating Function Overloading

#include <iostream>
using namespace std;

class Math {
public:
    // Function to add 2 integers
    int add(int a, int b) {
        return a + b;
    }

    // Function to add 3 integers
    int add(int a, int b, int c) {
        return a + b + c;
    }

    // Function to add 2 floats
    float add(float x, float y) {
        return x + y;
    }
};

int main() {
    Math obj;
    int choice;

    cout << "Choose an option:\n";
    cout << "1. Add 2 integers\n";
    cout << "2. Add 3 integers\n";
    cout << "3. Add 2 float numbers\n";
    cin >> choice;

    if (choice == 1) {
        int a, b;
        cout << "Enter 2 integers: ";
        cin >> a >> b;
        cout << "Result = " << obj.add(a, b) << endl;
    }
    else if (choice == 2) {
        int a, b, c;
        cout << "Enter 3 integers: ";
        cin >> a >> b >> c;
        cout << "Result = " << obj.add(a, b, c) << endl;
    }
    else if (choice == 3) {
        float x, y;
        cout << "Enter 2 float numbers: ";
        cin >> x >> y;
        cout << "Result = " << obj.add(x, y) << endl;
    }
    else {
        cout << "Invalid choice!\n";
    }

    return 0;
}
  

📘 Explanation:

This program demonstrates Function Overloading in C++. Function overloading allows us to define multiple functions with the same name but different parameter lists.

• int add(int, int) → Adds 2 integers
• int add(int, int, int) → Adds 3 integers
• float add(float, float) → Adds 2 floats

The compiler automatically decides which version of add() to call based on the arguments passed.

🧾 Sample Output:

Choose an option:
1. Add 2 integers
2. Add 3 integers
3. Add 2 float numbers
1
Enter 2 integers: 5 7
Result = 12
  

Choose an option:
1. Add 2 integers
2. Add 3 integers
3. Add 2 float numbers
2
Enter 3 integers: 2 4 6
Result = 12
  

Choose an option:
1. Add 2 integers
2. Add 3 integers
3. Add 2 float numbers
3
Enter 2 float numbers: 3.5 2.5
Result = 6
