Linked Lists And C -Programming

My last article on Pointers and Structures demonstrated the way pointers are used to access data within a C Program. This article will relate the concepts of pointers and structures to another mechanism, the linked list. The concept of the linked list is not unique to the CProgramming Language, it is also used in Pascal, however C does give a great deal of flexibility in the way it can handle data within a Linked List. Linked lists are used in QDOS to allocate user heap. Allocation of user heap is known as dynamic memory allocation in C, which will be addressed later in this article.
