C++ Template Generika (template-argument-list)

Ich versuche zu implementieren ist eine Zirkuläre Doppelt verkettete Liste, und ich habe keine wahrscheinlich mit der LinkedList-Implementierung selbst. Das problem, das ich habe ist, ermöglicht es, generische Parameter mit Hilfe von Vorlagen. Ich habe mehrere tutorials den Umgang mit Vorlagen, aber ich habe nicht gefunden, etwas bestimmtes, was ich zu tun versuche.

Ich glaube, ich habe die meisten der Fehler, aber ich bin noch immer der Fehler:

linkedlist.h(37): error C2955: 'Node' : use of class template requires template argument list
linkedlist.h(9) : see declaration of 'Node'
main.cpp(6) : see reference to class template instantiation 'LinkedList<T>' being compiled
      with
      [
          T=int
      ]

Hier ist mein code:

    Node * prev;            //pointer to the prev node
    T data;                 //placeholder for generic data

    Node(T d);          //constructor
};

template <class T>
Node<T>::Node(T d)
{
    next = NULL;
    prev = NULL;
    data = d;
    first = false;
}

//a circular doubly-linked list

    void insertBefore(T d); //inserts a node before the current node
    void insertAfter(T d);  //inserts a node after the current node
    void remove();              //removes the current node

Soweit ich bin mir bewusst, dass ich noch nicht viel schlechtes getan, nur muss ich korrigieren, die paar Fehler. Wenn ich etwas grundlegend falsch, wenn könnten Sie bitte zeigen Sie es mir, oder mir direkt auf eine entsprechende Ressource, es wäre sehr geschätzt werden.

Vielen Dank im Voraus.
