在c++中的重载运算符中使用局部变量

#include <iostream>

class Vector {
private:
    int x;
    int y;

public:
    Vector(int x, int y) : x(x), y(y) {}

    Vector operator+(const Vector& other) const {
        int resultX = x + other.x;  // 使用局部变量存储计算结果
        int resultY = y + other.y;
        return Vector(resultX, resultY);
    }

    void print() const {
        std::cout << "x: " << x << ", y: " << y << std::endl;
    }
};

int main() {
    Vector v1(1, 2);
    Vector v2(3, 4);

    Vector sum = v1 + v2;
    sum.print();  // 输出：x: 4, y: 6

    return 0;
}
