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

Try this:

template
struct U1
{
    U1();
    T   v[2];
    T&  x;
    T&  y;
};

template
U1::U1()
    :x(v[0])
    ,y(v[1])
{}

int main()
{
    U1   data;

    data.x  = 1;
    data.y  = 2;
}
