Explanation:

In C++, operator overloading allows you to define how operators (like +, -, *, ==, etc.) behave for objects of your class. To create an operator function, you use the operator keyword.

Example:

class Complex {

public:

    int real, imag;



    Complex(int r, int i) : real(r), imag(i) {}



    // Overload the + operator

    Complex operator+(const Complex& other) {

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

    }

};

Here, operator+ is the operator function.
