Generic Doubly-Linked List (C++)
by Bench on Jul 18th, 2007
This code snippet outlines a simple, no-frills linked list. Tested under MSVC++ 2003
and Comeau, but not guaranteed bug free. Snippet includes example main() .
This snippet is intended as an example of a possible implementation of a linked list
class (Of which there are many variations) For a better linked list, use the STL <list>
library.
