If you already know the answer then why are you asking the question? This is not a debate forum.

false, only protected or public members are visible. You can find more information on MSDN.

I am not asking is it visible or not..simply inherit or not??
Sure.?Check in MSDN itself again and confirm it...

V. 13-Apr-12 9:44am

If it's not even visible, do you think it is inherited?

samu4u 13-Apr-12 9:48am

Yes.

Please read my answer... it starts with "false, ..."

I am saying a derived class inherits the private members of a base class also.

V. 13-Apr-12 9:53am

Although I do not claim to be perfect, I kinda doubt that if I have a member say: private int id in base class A, I can use it in a derived class B. same for a method. If you think otherwise, I'll gladly accept your reasoning behind this. Or we could misunderstand each completely on terminology.

just conside i have a petrol car

class petrol:car
{
}
class car
{
private :carbody
protected:engine
public:steering
}

if the 'petrol' is inheriting from 'car'

the car is having 'carbody' also...

do u think that the car doesn't have carbody???

I've read the posts below and I see you're dilemma a little, it's probably a matter of wording, but If you have a private member in the base clase, it is not accessible by the deriving class and thus not 'inherited' (at least for me), however that does not mean that it is not instantiated or used in some way. The whole point in inheriting is that you can or use or override a certain behavior.

Solution 2

True.

Contrary to V.'s solution, just because it is not readily accessible does not mean it is not inherited. An instance of the derived class will still instantiate the private members of the base class, they just will only be accessible through the base class's methods.

A derived class has access to the public, protected, internal, and protected internal members of a base class. Even though a derived class inherits the private members of a base class, it cannot access those members. However, all those private members are still present in the derived class and can do the same work they would do in the base class itself. For example, suppose that a protected base class method accesses a private field. That field has to be present in the derived class for the inherited base class method to work correctly.
