The age member of the Base class is public, so it can be accessed directly from an object of the Base class. However, when
17+
it comes to the Derived class, which inherits from Base, the age member is not directly accessible because the inheritance is private by default in C++.

25+
In C++, if you do not specify an access specifier (`public`, `protected`, or `private`) when declaring a derived class, the inheritance is `private` by default.
26+
This means that public and protected members of the base class become private members of the derived class.
