class B {

  public:

    void f();

    int i;

};

To compensate for this limitation, a class can be associated with a class memory type. 
The class memory type changes:

●

the 

this

 pointer type in all member functions, constructors, and destructors into a 

pointer to class memory

●

the default memory for static storage duration variables—that is, not auto 
variables—of the class type, into the specified class memory

●

the pointer type used for pointing to objects of the class type, into a pointer to class 
memory.

class _ _far C {

  public:

    void f();       // Has a this pointer of type C _ _far *

    void f() const; // Has a this pointer of type

                    // C _ _far const *

    C();            // Has a this pointer pointing into far

                    // memory

    C(C const &);   // Takes a parameter of type C _ _far const &

                    // (also true of generated copy constructor)

    int i;

};

C Ca;               // Resides in far memory instead of the

                    // default memory

C _ _near Cb;        // Resides in near memory, the 'this'

                    // pointer still points into far memory

C _ _huge Cc;        // Not allowed, _ _huge pointer can't be

                    // implicitly casted into a _ _far pointer

void h()

{

  C Cd;             // Resides on the stack

}

C * Cp;             // Creates a pointer to far memory

C _ _near * Cp;      // Creates a pointer to near memory
