C++ Operator Overloading

Provide custom intuitive semantics for operators (+, -, ==, <<) on objects.

❮ Previous Next ❯

Operator overloading allows user-defined types to behave like primitive built-in types when used with standard operators like +, ==, and stream insertion <<.

Key Takeaways: C++ Operator Overloading

Mastering C++ Operator Overloading helps you write clean and reliable C++ code. Follow standard conventions, test edge cases, and keep logic simple. Try running the code example below and complete the exercises to build confidence.

C++ Operator Overloading Code Example

C++

#include <iostream>

class Vector2D {
public:
    int x, y;
    Vector2D(int x, int y) : x(x), y(y) {}
    Vector2D operator+(const Vector2D& other) const {
        return Vector2D(x + other.x, y + other.y);
    }
};

int main() {
    Vector2D v1(2, 3), v2(5, 7);
    Vector2D sum = v1 + v2;
    std::cout << "Sum: (" << sum.x << ", " << sum.y << ")\n";
    return 0;
}

Output

Sum: (7, 10)
