Can't use a struct(with template) inside a class

Question

I made a node struct with a template:

template <typename T>
struct Node{
        T data;
        Node* next;
        Node* prev;
};

It compiles fine but when I try to use it inside a class it gives me the error: invalid use of template-name 'Node' without an argument list

Answer 1

In another class' context, you need to add a template parameter instead of using plain Node* :

struct B
{
  Node<int>* next;
};
