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

Operator overloading allows you to define custom behavior for operators in your classes. 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?

Sure! Here's a simple example:

class Point {
public:
    int x, y;
    Point(int x, int y) : x(x), y(y) {}
    Point operator+(const Point& p) {
        return Point(x + p.x, y + p.y);
    }
};

In this example, adding two Point objects will return a new Point with the summed coordinates.

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

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

#include <iostream>
class Point {
public:
    int x, y;
    Point(int x, int y) : x(x), y(y) {}
    friend std::ostream& operator<<(std::ostream& os, const Point& p) {
        os << "(" << p.x << ", " << p.y << ")";
        return os;
    }
};

This allows you to use std::cout << point; to print the coordinates.
