WebNov 29, 2015 · You need a pointer to the node you want to delete but you only have it from the previous node, so if you have a linked list A -> B -> C -> D and you want to delete node C, you will have a pointer to it from node B, then you reassign next value of pointer B to node D, thus excluding node C from the linked list. WebTo keep the address of the linked list we will create a global pointer, let's say ‘head’, and initially, it will contain ‘NULL’. Node* head = NULL; 1. Insertion. Insertion means to add a …

WebDelete from a Linked List You can delete either from the beginning, end or from a particular position. 1. Delete from beginning Point head to the second node head = head->next; 2. Delete from end Traverse to second last element Change its next pointer to null
WebDeletion from end in circular linked list in C++ is one of the deletion operation that we can perform on the circular sequenced list. The other deletion operations that we can perform are:- Deletion from beginning i.e. to delete the head node of the list. Deletion from any specific position i.e. to delete any node from the list. WebDeletion Operation Now assume there are three nodes in the circular linked list, so the following possibilities may generate. 1. The First possibility is that we can delete the current node. 2. The Second possibility is that we can delete after node. Perform delete at beginning and end 1. First we need to traverse the first node to the last node.
