See if you can think of a better way before reading the second code example. After the insertion, the list consists of a single element, which is both the front and the back of the list. The first step of creating linked list of n nodes starts from defining node structure.
What you want is a copy paste brain-dead code, implementing a link list without knowing whats happening behind the scenes.
The obvious assumption is that there is at least 1 node in the list, so your argument is invalid. Input number of nodes to create from user, store it in some variable say n.
Thanks for this useful topic. Become an Author Submit your Article Linked list is one of the most important data structures.
You are missing the point of the tutorial teaching the concepts of how link list work and not error proofing the link list, that will make the tutorial out of scope. You can also have user defined types as node data section.
Linked lists are very useful in this type of situations. By Alex Allain Linked lists are a way to store data with structures so that the programmer can automatically create a new place to store data whenever necessary.
Learn how things work before making assumption about things. The node structure may vary based on your requirement.
Remember that the pointer only stores the memory location of something--it is not that thing itself--so the arrow points to the next struct. So far we know what the node struct should look like: One way to visualize a linked list is as though it were a train.
We can avoid this redundancy by allowing the conductor to walk off of the back of the train. What you are describing is an incomplete tutorial, which should still acknowledge where it is incomplete. Inserting to the front of the list is just a basic implementation of how a list is added to the front when a node is already created.
A linked list is made up of many nodes which are connected in nature. Exception handling is meant to be done by us programmers and not tutorials. The next part after the creation of a node is to join the nodes and create the linked list. If this is supposed to be just an introduction to how a linked list operates, maybe it should skip the code snippets completely.
Once it reaches a null pointer or dummy nodemeaning there are no more nodes train cars then it will be at the end of the list, and a new node can subsequently be added if so desired.
Then print some error message and terminate program, otherwise move to below step. This is how the program will traverse the linked list. We will use temp to store reference of previous node. I will explain step by step process to create and traverse a linked list of n nodes and display its elements.
Because there is no reason for a tail pointer to be updated if you add a node to the front, only the head pointer is needed to change because the head pointer is meant to keep track of the front of the list and tail pointer to the back of the list.One way to visualize a linked list is as though it were a train.
The programmer always stores the first node of the list in a pointer he won't lose access to. This would be the engine of the train. The pointer itself is the connector between cars of the train.
Every time the train adds a car, it uses the connectors to add a new car. A Comprehensive Guide To Singly Linked List Using C++. Published Dec 08, Last updated Jan 18, Now, we will write a function for the node creation. The process of creating node is very simple. (which we are going to create) in linked lists, then it is called both head and tail.

Linked list creation and traversal is the stepping stone in data structures. In this article, I will explain how to create and traverse a linked list in C programming. I will explain step by step process to create and traverse a linked list of n nodes and display its elements.
Now, we will create a class ‘linked_list’ which will contain all the functions and data members required for a linked list. This class will use the structure ‘node’ for the creation of the linked list.Download
