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

I was looking for a similair thing and eventually came up with a solution.

I was looking to have a data storage object that I could use as both an array of values and as individual values (for end-user flexibility in writing Arduino libraries).

Here is what I came up with:

class data{
    float _array[3];

    public:
    float& X = _array[0];
    float& Y = _array[1];
    float& Z = _array[2];

    float& operator[](int index){
        if (index >= 3) return _array[0]; //Make this action whatever you want...
        return _array[index];
    }
    float* operator&(){return _array;}
};


int main(){
    data Test_Vector;
    Test_Vector[0] = 1.23; Test_Vector[1] = 2.34; Test_Vector[2] = 3.45;

    cout<<"Member X = "<

Thanks to Operator overloading, we can use the data object as if was an array and we can use it for pass-by-reference in function calls (just like an array)!

If someone with More C++ experience has a better way of applying this end product, I would love to see it!

EDIT: Changed up the code to be more cross-platform friendly
