c++ - What is the value of private members here? -

-

if have 2 classes a , b, such b inehrits a. in other words, a base class, , b derived class.

now, suppose class a has private members. since class b inherited class a, private data members became part of class b.

as know, private members said not accessed derived classes, but, in derived class. value of privacy in case?

thanks.

they aren't usable in way member functions of b, useful member functions of a, b in turn rely on. it's level of encapsulation (b shouldn't care how functionality of a implemented).
