Question

How to write a user-defined operator in C++

Answer 1

#include <iostream>

class Point {
public:
    int X;
    int Y;

    // Constructor
    Point(int x, int y) : X(x), Y(y) {}

    // Overload + operator (user-defined operator)
    Point operator+(const Point& other) const {
        return Point(X + other.X, Y + other.Y);
    }

    // ToString equivalent
    void print() const {
        std::cout << "(" << X << ", " << Y << ")" << std::endl;
    }
};

int main() {
    Point p1(5, 8);
    Point p2(1, 2);

    Point result = p1 + p2; // Using overloaded + operator
    result.print();
}
