private members in internal class

[Glen Able]

So, given something like

class Outer
{
private:

class Inner
{
private:
int m_member;
};
};

Should Outer be allowed to access Inner's m_member or not?

GCC thinks yes, VC6 thinks no.

thanks!
glen.

No. Outer isnt allowed to access a private member of a nested class.

Unless 'm_member' is static, or there is some kind of
friendship involved, then no, not without an object of
type 'Inner', with an available accessor.

What do you mean with static? Even if m_member is static it shouldn't be
accessible.

Christoph?

Interesting; which version of GCC thinks so? IIRC VC6 is right on this
point.

Why not ?

Because its private.

Oop's ;-).

My apologies - I missed that it was private.
I need some shut eye <G>.

It's 2.95 or thereabouts, with some custom bits...

Thanks for all the replies!
