C++ nested classes accessibility

Question

Given the following code without considering friendship between two classes:

class OutSideClass
{
...
public:
    int i_pub;
protected:
             


        

Answer 1

As @Nawaz points out, in C++03 nested classes do not have special access rights to members of the enclosing class. However, this limitation is easy to get around by declaring the nested class as a friend.

class OutSideClass
{
...

    class InSideClass
    {
        ...
    };
    friend class InSideClass;
};
