Help me! I am stuck in LinkList

[shahab.burki]

Hi,
I am using Visula C++ and building LinkedList. But I am studk.

Please look at this if goes something wrong. Please mention it. Their are are two classes I am using for it. The first it Data Class and other one is Node class. Note that both classes are in separate files. Here is the Code.

#include <iostream>
#include <iomanip>
#include <string>


using namespace std;


class Data
{
private:


string name;


public:


void setName(string);
string getName();
};


void Data::setName(string str)
{
name=str;
}


string Data::getName()
{
return (name);
}


.........................................................................................................


#include <iostream>
#include <iomanip>
#include <string>
#include "Data.h"


using namespace std;


class Node
{
private:


Data obj;
Node *link,*start,*last;


public:


Node()
{
link=NULL;
start=NULL;
last=NULL;
};



void setLink(Node*);
Node* getLink();
void setStart(Node*);
Node* getStart();
void setLast(Node*);
Node* getLast();
Node* createNode(string);
void insertNode(Node*);
void displayNodes();


};


int main()
{
Node myObj;


myObj.insertNode(myObj.createNode("Shahab"));
myObj.insertNode(myObj.createNode("Guldan"));
myObj.displayNodes();


return 0;
}


Node* Node::createNode(string str)
{
Node *newNode=new Node();


newNode->obj.setName(str);
newNode->setLink(NULL);


return newNode;


}


void Node::insertNode(Node *newNode)
{


if(getStart() && getLast()==NULL)
{
setStart(newNode);
setLast(newNode);
}
else
{
Node *temp;


temp=getStart();


while(temp->getLink()!=NULL)
{
temp=temp->getLink();
}


temp->setLink(newNode);


setLast(newNode);
}
}


void Node::displayNodes()
{


Node *temp;


temp=getStart();


while(temp->getLink()!=NULL)
{
cout<<"This is the List:  "<<temp->obj.getName();


temp=temp->getLink();
}


}


void Node::setLink(Node *lnk)
{
link=lnk;
}


Node* Node::getLink()
{
return(link);
}


void Node::setStart(Node *newNode)
{
start=newNode;
}


Node* Node::getStart()
{
return (start);
}


void Node::setLast(Node *newNode)
{
last=newNode;
}


Node* Node::getLast()
{
return (last);
}

Thanks

What is your problem? Compile errors? Your node class seems a little off to me also. What are the other pointers supposed to be for? Most linked lists only have pointers to the next and/or previous item (see http://en.wikipedia.org/wiki/Linked_list)
