try google + "linked lists"

Linked list are typically used to work with data structures.
Access to items in the list is controlled by pointers.

This is a very simple example to construct a linked list. You will need to do a lot more reading to use them correctly.

One thing to remember:
You must delete all the list items when exiting the program otherwise you will create a memory leak.

struct dataRec {
  type     data;
  dataRec  *next;

dataRec *prList = NULL;  // the list anchor

function addRecord(dataRec *prList) {
  dataRec *temp = new dataRec;  // create a new record to add to list
  temp->data = whatever;
  temp->next = NULL;

  // Now add this record to the end of the list
  dataRec *curr = prList;	
  if (curr == NULL) {  // the list is empty
    prList = temp;  // prList, the anchor, now points to the first record
  else {
    if (curr->next == NULL) { // last record in list
      curr->next = temp;  // add temp to end of list
    else {  // move up the list until the last entry
      curr = curr->next;

thanks, i really appreciate it! i think i'll do some head crackinh for awhile to master this ^^
