C++ union array and vars?

Question

There\'s no way to do something like this, in C++ is there?

union {
    {
        Scalar x, y;
    }
    Scalar v[2];
};

Where x == v[0]<

Answer 1

Since you are using C++ and not C, and since they are of the same types, why not just make x a reference to v[0] and y a reference to v[1]
