Linked list node

[looptesting]

Hi guys, I was just wondering why I kept getting the error message:
Error: identifier "curr1" is undefined.

my header:

class llist{
private:
	struct Node{
		Node* next;
		int data;
	};
	Node* head;
public:
	llist(){ head = NULL; }
	void addNode(int);
	void delNode(int);
	void iterate();
};

my llist.cpp file

#include "llist.h"
#include <iostream>

using namespace std;

void llist::iterate(){
	Node* curr;
	curr = head;
	if(head != NULL){
		curr = head;
		while(curr!=NULL){
			cout << curr->data;
			curr = curr->next;
		}
	}
	else 
		cout << "\n no llist \n";
}

void llist::addNode(int x){
	Node* node;
	node->next = NULL;
	node->data = x;
	if(head == NULL)
		node = head;
	else 
		Node* curr1;
		curr1 = head;
		while(curr1->next != NULL){
			curr1 = curr1->next;
		}
		node = curr1->next;
}

I am getting the error in addNode where I initialize curr1 to head
I have my #include "llist.h"
so I'm not sure why exactly it is saying it is unidentified

Thanks for the help!

Hint: Have a look at the else side in addNode()

Oh I see, I needed the braces, else curr1 would be declared within the scope of else, therefore not being seen by the rest of the program?

Now I am getting an error saying that in line 22,
I am using the variable node without first initializing it.
I thought that was what I did at line 21 with Node* node;?

You need to be doing something along the lines of:

void llist::addNode(int x){
    Node* node = new Node;
    node->next = NULL;
    node->data = x;
    if(head == NULL)
        head->next = node;
    else 
    {
        Node* curr1;
        curr1 = head;
        while(curr1->next != NULL)
        {
            curr1 = curr1->next;
        }
        curr1->next = node;
    }
}

NB: I'm very tired and off to bed as I have to get up in six hours for work, hope it helps.

Oh ok well thank you for the help I think I can get it from here.

You will need to look at deleting the nodes in the list when you have finished with them.
