Answer 1

I assume this fails because the [] operator is not a valid operation on your variables me, other, etc.

• Did you overload the [] operator on your Region<> class? If so, does it return an object which actually has these min and max members? — Does the overloaded operator return an object, an object by reference, or a pointer to an object? (In the last case, you'd need to replace . by ->.)

• If you haven't overloaded [], then me, other etc. would have to be declared as an array for your code to be valid.
