cannot initialize a variable of type 'Node *' with an rvalue of type 'const Node *'

Question

What is the problem here, &head should yield a pointer to a Node and that is the type of cur but apparently there is a type mismatch?

I am trying to print the elements of a linked list using its head

void printList(const Node& head){
  Node* cur = &head;
  cout<<"[ ";
  while(!(cur==0)){
    cout<<cur->x<<" ";
    cur = cur->next;
  }
  cout<<"]"<<endl;
}

cannot initialize a variable of type 'Node *' with an rvalue of type 'const Node *' is the error

Answer 1

Do Node* cur = head; or const Node* cur = &head;

This is because head is a const reference and you can't assign it to plain cur(which is NODE*).
