error C2146 and error C2501

[Tim]

I created a header file including a Node Class and a
NodeList Class.

class Node{
Node* next;
};

class NodeList{
Node* first;
Node* last;
};

I wanna declare a NodeList inside the Node but since
NodeList is declared after Node it gives me this error

class Node{
Node* next;
NodeList list;
};


I get:
error C2146: syntax error : missing ';' before identifier 'list'
error C2501: 'Node::list' : missing storage-class or type specifiers
error C2501: 'Node::NodeList' : missing storage-class or type
specifiers

I tried to include both in different header files with each one
referencing the other but it was a wrose idea since the linker was
looping

Is there any way I can overcome this?
Thank you

Put the following in one header file

class Node; // forward declaration

class NodeList{
Node* first;
Node* last;
};

class Node{
Node* next;
NodeList list;
};

One class per header file is a good idea in general, but its not when
classes are as tightly dependent on each other as these two are.
