What is operator overloading and how does it work in different programming languages?

Operator overloading allows developers to define custom behavior for operators (like +, -, *) for user-defined types.

Can you give me an example of operator overloading in Python?

Sure! In Python, you can overload the + operator by defining the add method in your class. For example:

class Vector:
    def __init__(self, x, y):
        self.x = x
        self.y = y

    def __add__(self, other):
        return Vector(self.x + other.x, self.y + other.y)

How does it differ in C++?

In C++, operator overloading is done using operator functions. For example:

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

Are there any languages that don't support operator overloading?

Yes, some languages like Java do not support operator overloading directly, but you can achieve similar functionality through method overloading.
