How can we access private members of base class through sub class when inhertance is done??

Answer 1

The simplest way is to declare the private members of the base class as protected instead.

class Base{
protected:
...
}

If you really need the members private, you can otherwise declare the derived class as a friend of the base class in the base class definition.

class Base{
friend class Derived;
};

Answer 2

Private scope is *especially designed* to prevent access from any other entity than the class and it's instances. If you want to access a member better use protected scope as already was pointed out.
