C++ :: Linked List Not Increasing In Size

I'm trying to implement a linked list using my own node class. I've created functions to add to the head and tail, return the size of the linked list as well as the value stored within the current pointer.

However, my problem is that when I wrote a test program to see whether my list worked, my list did not appear to increase in size past 1 item in the list.

this is the test program I wrote:

int main() {
int counter,
data;
linkedlist *my_list = new linkedlist();
cout << my_list->size() << endl;
for (counter = 0; counter < 5; counter++) {

[Code] ....

I'm sure it's probably something simple that I've overlooked . But I'm still relatively new to the concept of dynamic memory allocation.
