1)if Class A is base class for Class B then the private data members of base class are inherited or not?
I think they are inherited but we can't access them.

2)Protected data members of base class can be accessed by object of a derived class or only public member function of derived class.

1)
Private members of the base class are part of the derived class object - however, as you had specified, they cannot be accessed by derived class member functions.
2)
Protected members of base class may become protected or private in the derived class, depending on the type of derivation - and as such can be accessed only by member functions of the derived class.
I am providing this answer, not taking into consideration friend classes and functions
thanks
