Answer 1

As both Neil Butterworth and Luc Danton noted, you can't have a pointer of type Node* because Node is not a type. It is a template. Yes, Node is a class template, but that class here just qualifies the kind of template. One way to look at it: Just as classes and instances of classes are very different things, so too are templates and template instantiations. It is those template instantiations such as Node that are classes. The class template is some other kind of beast.
