help in link list

hello . ive got a simple question.
how do i create a method in my class which tells me the size of my list

..............
int size(void){
int s=0;
for (pos = begin(); pos.not_equal(e nd()); pos.next())
{s++;}
return s;
}
...............

here is the methods for begin and end:

Iterator List::begin()
{ Iterator iter;
iter.position = first;
iter.last = last;
return iter;
}

Iterator List::end()

{ Iterator iter;
iter.position = NULL;
iter.last = last;
return iter;
}

STL already has a list class, and all of this is implemented already. I see you are using iterators, you could do that. However, for your code, you should be getting an infinite loop? You aren't updating the position cursor after each loop. It sits at the first element counting it infinitely many times.

int size(void)
{
  int s=0;
  for (pos = begin(); pos.not_equal(end()); [b]pos = [/b]pos.next())
    s++;
  return s;
}
