going to the begging of a linked list( the head node)
How do I go to the Head node in a linked list?
I would need to do this when scaning and I want/need to scan from the begging.

not really sure if I have enuf information to answer you. Usually when you have a linked list, you maintain a variable that points to the head (a pointer). That way you can always reference the head. Another method is that liked lists can have double links, that is each link points to it's sucessor and predecessor. Working backwards thru the list,you stop when the predecessor is 0/null indicating the beginning of the list
