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

With C++11 you have anonymous unions and structs which just export their definitions to the enclosing scope, so you can do this:

typedef int Scalar;
struct Vector
{
    union
    {
        struct
        {
            Scalar x, y;
        };
        Scalar v[2];
    };
};
