LinkedList Complete code in C language

Linkedlist complete code in Clanguage.
Code Demonstration: In this code I've made the code for insert a value in the linked list, delete a value from a specific position from the linked list, search an item from the linked list and get the total size of the linked list and also print the linked list finally...
