Topics discussed in this section: 15-1 List Implementations The C language does not provide any list structures or implementations. When we need them, we must provide the structures and functions for them. Traditionally, two data types, arrays and pointers, are used for their implementation. Topics discussed in this section: Array Implementation Linked List Implementation Pointers to Linked Lists Computer Science: A Structured Programming Approach Using C

Topics discussed in this section: 15-2 General Linear Lists A general linear list is a list in which operations, such as retrievals, insertions, changes, and deletions, can be done anywhere in the list, that is, at the beginning, in the middle, or at the end of the list.. Topics discussed in this section: Insert a Node Delete a Node Locating Data in Linear Lists Traversing Linear Lists Building a Linear List Computer Science: A Structured Programming Approach Using C
