Question

What I want to do is have a singly linked-list class with a default constructor, copy constructor, copy assignment constructer, and destructor. I barely started it because I am confused if a Node with int data and next pointer should be a separate class or the way I did it.

class list {
public:
    list(): next(NULL) {} // default constructor                                   
    list(const list &t){} // copy constructor                                     
    list&   operator= (const list &t) // assignment operator                        
    ~list(){} //destructor                                                        
    void print()    

private:
    struct Node {
        data x;
        Node *next;
    }_list;
}

Well, logically, a node is a separate structure (class), but in common implementations, the list itself is represented by the first node.

So, basically, you wouldn’t have a list class (and if you did, it’d just hold a pointer to the first node + the constructors/assignment operator/destructor):

struct Node {
  data x;
  Node *next;
};

class list{
 public:
  list(): next(NULL) {} // default constructor                                   
  list(const list &t){} // copy constructor                                     
  list& operator= (const list &t) // assignment operator                        
  ~list(){} //destructor                                                        
  void print() ;

 private:
  Node* first;
}
