Is friendship inherited in C++?

Question

Suppose I have a Base class:

class Base {
    friend SomeOtherClass;
};

And there is another (different) class that inherits from Base :

class AnotherClass : public Base {}

Is friendship inherited as well?

Answer 1

In principle, a derived class inherits every member of a base class except:

* its constructor and its destructor
* its operator=() members
* its friends

So, no. Friends are not inherited.

Answer 2

No it isn't.

Edit: To quote from the C++ Standard, section 11.4/8

Friendship is neither inherited nor transitive.

Answer 3
