Creating new node using nested class? HELP CONFUSION

[Ramzi89]

Hi im trying to create a circular linked list in which after the first entries all subsequent entries are inputed after the first. Compiler errors are occuring on the lines where im trying to create a new Node (ie Node::Circlist). Am i doing this wrong? can i create more objects from the nested class within one object of the primary class?

class Circlist
{ public:
	Circlist();			// default constructor
	void addnode(string sx);	// adds name sx to the circle
	string select(int n);		// removes every nth, returns winner
	void display( ) const;		// displays contents of list
  private:
	class Node;
	Node* start;
};

class Circlist::Node
{ public:
	Node(string sx) : s(sx), link(NULL) { }
	string s;
	Node* link;
};


void Circlist::addnode(string name)
{
Node* p;
Node* temp;
if (start == NULL)
{start = new Node;
 start -> s = name;
 start -> link = start;
 }
else if (start -> link == start)
{
start -> link = new Node;
p = start -> link;
p -> sx = name;
p -> link = start;
}
else
temp = start -> link;
start -> link = new Node;
p = start -> link;
p -> link = temp;
p -> sx = name;
}

hmmm?

Your constructor requires a string param.

void Circlist::addnode(string name)
{
Node* p;
Node* temp;
if (start == NULL)
{start = new Node(name); // pass name to constructor
 start -> link = start;
 }

...

changed the
start = new Node;

to

start = new Node(sx);

the whole way through. Don't really know why that compiled? Is it because the constructor of Node required a string argument i.e sx?

Yes!
