If you cannot come up with this yourself, when you are explicitly told that you must change mpNext, and that pItem is to be set as the next link, then it's pretty much hopeless anyway.

man, i came up with that already but it was by accident. I should have listened in C programming. the thing is, i hated pointers, im pretty much good at everything else except pointers. Thanks anyways. I came up with the Queue and QueueIteam definitions already.

Code:

//member function definitions for class Date
#include <iostream> //allows program to output data on screen
using std::cout;
using std::endl;
using namespace std;

#include <iomanip>
using std::setfill;
using std::setw;

#include <string>
using std::string;
using std::strcpy;

#include "Queue.h"  //include definition of class Queue from Queue.h




Queue::Queue ()
{
	mpHead = NULL;
	mpTail = NULL;
}

void Queue::addItem(char *pData)
{
	//create and initialize new QueueItem dynamically
	QueueItem *pQI = new QueueItem(pData, ++mNodeCounter);

	if ( NULL == mpHead ) // 
		mpHead = mpTail = pQI;
	else
	{
		// li
		mpTail = pQI;
	}
}

void Queue::removeItem()
{
	delete mpHead;
}

void Queue::printList()
{
	cout << mpHead << endl;
	cout << mNodeCounter << endl;
}
Queue::~Queue()
{
}

Code:

//member function definitions for class QueueItem

#include  <iostream> // allows program to output data
using namespace std;

#include  <string> 

#include "QueueItem.h" // include definition of class QueueItem from QueueItem.h

QueueItem::QueueItem(char *pData, int id)
{
	id = mNodeID;
	pData = mData;
}
void QueueItem::setNext(QueueItem *pItem)
{
	QueueItem* mpNext = pItem;
}

QueueItem* QueueItem::getNext()
{
	return  mpNext;
}
int QueueItem::getId()
{
	return mNodeID;
}

const char* QueueItem::getData()
{
	return mData;
}
