Explanation / Answer
automatic ClassA must not have private data members. be directly and indirectly accessed by a derived class. can directly initialize any members inherited from the base class. class dClass: private bClass{ //classMembersList}; class dClass: private bClass{ //classMembersList}; Going from a general description to a more specific description namespace
