Write a C Program to implement singly linked list operations. Linked list is a linear data structure that contains sequence of elements such that each element links to its next element in the sequence.
Each link contains a connection to another link. Each node consists of its own data and the address of the next node and forms a chain. Linked Lists are used to create trees and graphs. Linked list head always points to the first node and the last node always points to NULL. We can traverse the list from head to the last node but not in other direction.
A linked list node is represented by a C structure struct with two parts, 1 value or data and 2 link. We defined the value part as integer here but it can be arbitrarily complex. The link next is a pointer that points to the same data structure. It holds the next node pointer. But the last node next pointer is always NULL ,. The head pointer always points the first node. Initially it is assigned with NULL but it will point to the first node if there will be nodes in the list. Read also: Insert an element into a linked list at any position.
I write here to help the readers learn and understand computer programing, algorithms, networking, OS concepts etc. The first part is to create a node structure. The second and the most important part of a linked list is to always keep the track of the first node because access to the first node means access to the entire list.
We have made three nodes — head, prev and p. You will see the function of prev in the explanation of the next block of code. Try to understand the code by allocating two to three nodes by above mechanism and you will get it. Please login to view or add comment s. Become an Author Submit your Article.
