Create a newNode and assign some data to its data field. Create a new node… 2. There are three different types of insertions that you have to code for: [code ]insertFirst[/code], [code ]insertBefore[/code] and [code ]insertAfter[/code]. Head of a linked list always points to the first node if there is at least one element in the list. In Linked list, a node consists of two parts, a data and a pointer to next node. Imagine our linked list is not necessarily sorted and there is no reason to insert a new node in any special place in the list. A Linked list is a linear data structure which consists a group of nodes and each node points to next node by means of a pointer. Suppose we want to insert a new node in the circular linked list at 3 position i.e. Use the following steps for this purpose. 1. Insertion in doubly linked list after Specified node. We will follow below steps to insert node at 2 nd position in the list. Create a new node dynamically (by allocating a memory). C program to count number of nodes of a Singly Linked List. A Linked list consists of a set of nodes and each node has some data and a pointer to next node. C program to delete a node from the end of a Singly Linked List. An algorithm that does so follows. Allocate the memory for the new node. In order to insert a node after the specified node in the list, we need to skip the required number of nodes in order to reach the mentioned node and then make the pointer adjustments as required. And the new node will point where head was pointing to before insertion. Algorithm. Steps to insert new node in a Circular linked list. 2) If the value of the node to be inserted is smaller than the value of the head node, then insert the node at the start and make it head. Here is a C program to insert an element in a linked list Insert New Element at the Front of the Linked List. If the head node is Null, then insert the data in the head node. 1. Algorithm to insert node at the beginning of a linked list. Algorithm of insertion at the beginning. The list initially contains 3 nodes. Then we have an easiest place to insert the node is at the beginning of the list. just after 2 nd position. C program to insert a node at the beginning of a Singly Linked List. Algorithm: Let input linked list is sorted in increasing order. C program to reverse a Singly Linked List. 1) If Linked list is empty then make the node as head and return it. So inserting a new node means the head will point to the newly inserted node. C program to delete all nodes of a Singly Linked List.
