base class A in B). Because the members in base class A are already private in Class B, Class C does not inherit any members of Class A and cannot be converted to a base class. (4) In the case of protected inheritance, a member of a subsequent derived class (a derived class C of Class B) can be converted to a base class type (Class A) (a member function, by virtue of its own member function) (because protected inherits, the natural derived class can access the base class member, A member of a b
(); }}The output is as follows: The overridden method of the parent class can be called inside a subclass, but the overridden method of the parent class cannot be called externally.This is due to encapsulation considerations, to avoid external programs calling the overridden method of the parent class directly, and avoiding the subclass's new validation logic for the overridden method. Also for encapsulation purposes, the subclass can invoke the overridden method of the parent class, such as
