Help wanted. C++ question.

How do I declare a global object 'within' the class's brackets?

class Box{

public:
int x, y;
//Here's the problem.
Box A;//?

bool collision(Box A, Box B){}

}A, B;

Is it even possible to declare global objects within a class? Yes/no? Depending on your answer I may:
 
a) Drop out of college and become a plumber.
b) Kill myself.
c) Finish the app I'm currently working on.

It means box is a reference parameter of type Box. This avoids copying box when you pass it to this function. It actually should have been as follows, since box should not be getting changed.

bool collision_with(const Box &box)
