This is a basic tutorial on how to create link lists in C and C++. I assume you are quite comfortable with pointers. If not I suggest you read Pointers in C by Yashwant Kanetkar. Alternatively chapter 5 of The C Programming Language by Kernighan and Ritchie makes for good reading.
I might put up a pointer tutorial at some later point of time. Anyways, this tutorial starts off by explaing the need for link lists then it explains how you can perform various operations on simple linked lists.
