access private members in inheritance

c++, inheritance, private

Solution

Quick answer: You don't. Thats what the `protected` key-word is for, which you want to use if you want to grant access to subclasses but no-one else.

`private` means that no-one has access to those variables, not even subclasses.

If you cannot change code in `A` at all, maybe there is a `public`/`protected` access method for that variable. Otherwise these variables are not meant to be accessed from subclasses and only hacks can help (which I don't encourage!).

Problem

I have a class A, which have a field val declared as private. I want to declare a class B, that inherit from A and have an access to val. Is there a way to do it on C++? I want to do it because I need to overload some functions of A, without changing A code at all. Thanks.
