Operator Overloading in OOPs

 #include <iostream>

using namespace std;

// class Print {

// public:

//     void show(int x) {

//         cout << "int: " << x << endl;

//     }    

//     void show(string str) {

//         cout << "string: " << str << endl;

//     }

// };

class Complex {

    int real;

    int img;

public:

    Complex(int r, int i) {

        real = r;

        img = i;

    }

    void showNum() {

        cout << real << " + " << img << "i \n";

    }

    //Operator overloading

    Complex operator + (Complex &c2)

    {

        int resReal = this->real + c2.real;

        int resImg = this->img + c2.img;

        Complex c3(resReal, resImg);

        return c3;

    }

};

int main() {

    Complex c1(1, 2);

    Complex c2(3, 4);

    c1.showNum(); // mistake:- tried printing using cout

    c2.showNum(); // same mistake tried printing using cout

   

    Complex c3 = c1+c2;

    c3.showNum();

   

    return 0;

}

OUTPUT:

1 + 2i 3 + 4i 4 + 6i
