Scope
The class name which is introduced in the friend class declaration its scope is not in class granting friendship and also is not the member of the class granting access. If the name of the friend class is declared before the friend class declaration then the compiler searches for the class with the same name as the friend class at the scope of friend declaration. If the name of the friend class is same as that of the enclosing class which is nested then the nested class is a friend of enclosing class.
