Thread: need help with FIFO QueueItem member definitions

Code:

//QueueItem.h
//Declaration of class QueueItem


#ifndef QUEUEITEM_H
#define QUEUEITEM_H



class QueueItem
{
public: 
	  QueueItem(char *pData, int id);  // constructor
      void setNext(QueueItem *pItem); //set pointer to next Item
      QueueItem* getNext();			//get pointer to next Item
      int getId();					//get Id
      const char* getData();		//get data member

private:
      char mData[30];  // or, use a char* if you want to dynamically alloc memory 
      int mNodeID;
      QueueItem * mpNext;			// pointer to another object of same type
};//end class QueueItem

#endif

//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)
{
 if ( pItem->mpNext != 0 )
	 pItem->mpNext
}

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

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

I can't seem to come with member definitions for class QueueItem, can somebody tell me what i'm doing wrong??
