copy constructor for a linked list classes
<p>So I want to copy a whole linked list classes, I have trouble figuring it out how to do so, </p>

<pre><code>class list{
   public:
  list(const list &amp;t);
private:
  struct Node{
    int x;
    Node *next;
  }*p;
</code></pre>

<p>I started with something like this:</p>

<pre><code>list::list(const list &amp;t){
  Node* q;
  q=new Node;
  while (p!=NULL){
    q-&gt;x= p-&gt;x;}
}
</code></pre>

<p>but I'm not sure if I am on the right track or what. I also have trouble how should I test such a copy constructor? For example I have list l1, then i insert couple integers into a list and then how I can copy it? </p>
