C++ program to overload binary operator `+' to add two complex numbers.

 Objective: Write a C++ program to overload binary operator `+' to add two complex numbers.

Code:

#include <iostream>

using namespace std;

class Complex {

private:

    float real;

    float imag;

public:

    // Constructor to initialize complex number

    Complex(float r = 0, float i = 0) : real(r), imag(i) {}

    // Overloading the '+' operator to add two Complex numbers

    Complex operator + (const Complex& other) {

        return Complex(real + other.real, imag + other.imag);

    }

    // Function to display the complex number

    void display() const {

        cout << real << " + " << imag << "i" << endl;

    }

};

int main() {

    // Creating two Complex objects

    Complex c1(3.4, 5.6);

    Complex c2(1.2, 3.8);

    // Adding two complex numbers using the overloaded '+' operator

    Complex c3 = c1 + c2;

    // Displaying the result

    cout << "Complex number 1: ";

    c1.display();

    cout << "Complex number 2: ";

    c2.display();

    cout << "Sum of Complex numbers: ";

    c3.display();

    return 0;

}

Output:
