They are variables which points to an object. Suppose you want the contents of a webpage. I could send you all the contents myself, but it is more useful to send an url. it takes less memory. A pointer is the url in this analogy. You create by putting a class name, then add a * and then insert the pointer name. You initialize them with the new operator. As an example: Node* next = new Node; There are other ways to initialize them but you should find that on the internet, as there is a lot to say about pointers.
