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

Depending on what "Scalar" is, yes, you can do that in C++. The syntax is almost exactly (maybe even exactly exactly, but I'm rusty on unions) what you wrote in your example. It's the same as C, except there are restrictions on the types that can be in the unions (IIRC they must have a default constructor). Here's the relevant Wikipedia article.
