Question from the C++ test

It allows a class to offer privileged access rights to another class or function.

Friendship privileges are inherited.

If the Romain class declares that the Helene class is a friend, and the Helene class declares that Emilie is a friend, the Emilie class automatically has special access rights to Romain objects.

If the Romain class declares that the Helene class is a friend, Romain objects do not automatically have special access rights to Helene objects.
