Operator Overloading

This example shows how to overload the + operator for a custom class.

cppCopy code#include <iostream>

class Vector {
public:
Vector(int x, int y) : x(x), y(y) {}
// Overloading the + operator
Vector operator+(const Vector&amp; other) {
    return Vector(x + other.x, y + other.y);
}
void display() {
    std::cout &lt;&lt; "Vector(" &lt;&lt; x &lt;&lt; ", " &lt;&lt; y &lt;&lt; ")" &lt;&lt; std::endl;
}
private:
int x, y;
};

int main() {
Vector v1(1, 2);
Vector v2(3, 4);
Vector v3 = v1 + v2; // Calls operator+
v3.display(); // Output: Vector(4, 6)
return 0;
}
