This document contains C code to implement a linked list and array-based list data structure (ADT). It includes functions to create, insert, delete, search and display elements in the list. For the linked list implementation, nodes containing data and pointer to next node are used. Functions like create, insert, delete manipulate the pointers to manage the list. The array implementation uses an array to store elements and tracks the number of elements. Functions perform similar operations of adding, removing and searching elements in the array representing the list.
