A horrible piece of C++

//Can this be refined?

template<class T> class Vector2
{
public:
    T x, y;

    Vector2(T cx, T cy)
    {
        x = cx;
        y = cy;
    }
    Vector2 operator+(Vector2 rhs)
    {
        decltype(rhs) temp(0, 0);
        temp.x = this->x + rhs.x;
        temp.y = this->y + rhs.y;
        return temp;
    }
};
