What are some examples of operator overloading in C++?

Can you explain operator overloading in C++ with some examples?

Sure! Operator overloading allows you to redefine the way operators work for user-defined types. For example, you can overload the '+' operator to add two objects of a class.

Can you show me a simple example of overloading the '+' operator?

Absolutely! Here's a simple example:

class Complex {
public:
    float real, imag;
    Complex operator+(const Complex &obj) {
        Complex temp;
        temp.real = real + obj.real;
        temp.imag = imag + obj.imag;
        return temp;
    }
};

In this example, the '+' operator is overloaded to add two Complex objects.

What about overloading the '<<' operator for output?

Great question! You can overload the '<<' operator to print your class objects. Here's how:

#include <iostream>
class Complex {
public:
    float real, imag;
    friend std::ostream& operator<<(std::ostream &out, const Complex &c) {
        out << c.real << " + " << c.imag << "i";
        return out;
    }
};

This allows you to use std::cout << c; to print a Complex object.
