Nested Class - Friend Class - Private Variable

BTW, which version of VS are we talking about?

2005

So this is SP1 fix I guess.

Thx  jkr

Here's some more info from MSDN. I may have to differ from what jkr is saying:

and some more on the scope

>> The Question is is SP1 wrong?

Actually, to the letter of the C++ standard, SP1 is wrong (at least as I interpret the standard).

The standard does not say anywhere that private members of A should be accessible from a nested class C of friend class B. It only says that (obviously) friend class B (including its member functions and static data members) should have access to A's privates.

That does make sense too, since the B::C class was not declared a friend of the A class, so why should it have access to its privates ?

Consider (as a side note) that a class doesn't even have access to the privates of a nested class :

class A {
  public :
    void fun1() { class B b; b.mb; }   // OOPS : A::B::mb is private
    void fun2() { class C c; c.mc; }   // OK : A is a friend of A::C
 
  public :
    class B {
      private :
        int mb;
    };
 
    class C {
      private :
        int mc;
 
      friend class A;
    };
};

infinity's comment reiterates what i pointed out through my links....private members cannot be accessed anywhere outside their class other than of course by their friends

Infinity and trin

 I Agree with you that a Nested class should not be available from a friend as I asked in the question.

It appears that this was **broken** in SP1!  

jkr what do you think?

Uped the points so I can split
