Can I treat a struct like an array?

Question

I have a struct for holding a 4D vector

struct {
    float x;
    float y;
    float z;
    float w;
} vector4f

And I\'m using a library th

If I had this situation, this is what I would do: C++ member variable aliases?

In your case it would look like this:

struct {
        float& x() { return values[0]; }
        float& y() { return values[1]; }
        float& z() { return values[2]; }
        float& w() { return values[3]; }

        float  operator [] (unsigned i) const { return this->values_[i]; }
        float& operator [] (unsigned i)       { return this->values_[i]; }
        operator float*() const { return this->values_; }

private:
        float[4] values_;
} vector4f;

However, this doesn't address the question of treating a struct as an array if that's specifically what you wanted to know about.
