Node Class inside the LinkedList class

I want to create a class of LinkedList and I have to put the class of Node inside of the class of LinkedList, how do you prefer me to do it?

I think something like:

Class LinkedList {
  private:
    class Node* head;
  public:
    class Node {
      private:
        int data;
        Node* next;  
        Node* prev;
    };
};

but I think this is not good.

I would do it like this

class LinkedList {
  private:
    struct Node {
        int data;
        Node* next;  
        Node* prev;
    };
    Node* head;
  public:
    ...
};

No need for anything in Node to be private since it's not useable outside of LinkedList.
