Thread: subscipt overload (returning reference to array?)

Hi all,

I'm a bit stumped about the idea of returning a reference to an array inside a struct. For example,

Code:

struct MyStruct
{
     float x, y;

     float& operator [](int i)
     {
          return ((&x)[i]);  // this confuses me
     }

I can use the overload to access x and y by using their corresponding subscripts. But how does that work? I understand incrementing a pointer to x will give me y if I dereference it. The overall syntax of that return confuses me.

Hope someone can help me
