Deletion from end in singly linked list in C++

How to delete element from end in Singly Linked List in C++?

In this article, let’s see how to code a C++ Program for deleting the last/end node of a singly linked list.

Steps to delete an element from end in singly linked list

Following steps are followed for deletion of an element from the end in a singly linked list.

  • Check if the Linked List is empty as we can not delete from an empty Linked List
  • Check if the Linked List has only one Node
  • In this case, just point the head to NULL and free memory for the existing node
  • Otherwise, if the linked list has more than one node, traverse to the end of the Linked List
  • Point next of 2nd Last node to NULL
  • Free the memory for the last node.

Defining a singly linked list in C++

Nodes of singly linked list is created by using the code mentioned besides.
This set of code will construct linked list by creating each node of the list.

class Node  
{   
    int data;  
    Node *next;  
};
