C++ Program for Function Overloading Using Parameter Order

#include <iostream>
using namespace std;

class maths
{
public:
    void display(int a, double b)
    {
        cout << "Integer is: " << a
             << " and Double is: " << b << endl;
    }

    void display(double b, int a)
    {
        cout << "Double is: " << b
             << " and Integer is: " << a << endl;
    }
};

int main()
{
    int a;
    double b;
    maths m;

    cout << "Enter integer and double:" << endl;
    cin >> a >> b;
    m.display(a, b);

    cout << "Enter double and integer:" << endl;
    cin >> b >> a;
    m.display(b, a);

    return 0;
}
  

📘 Explanation:

This program demonstrates function overloading in C++ using different order of parameters. Even though both functions have the same name display(), they are treated as different functions because the parameter sequence is different.

• display(int a, double b) — displays an integer first and then a double.
• display(double b, int a) — displays a double first and then an integer.

The compiler determines which function to call based on the order and type of arguments passed. This is an example of compile-time polymorphism.

🧾 Sample Output:

Enter integer and double:
10 5.5
Integer is: 10 and Double is: 5.5
Enter double and integer:
3.14 7
Double is: 3.14 and Integer is: 7
