9.8.1 Working with private derivation

Earlier, we had compile time error with private derivation. We can modify that Program 9.2 (private2.cpp), therefore, it works fine. Well, this is only working indirectly. We do not recommend this as a standard programming practice.

Problem: Rewrite Program 9.2 such that we could access private members of the base class.

Solution: See Program 9.5.

Program 9.5 Private derivation
