Program for linked list in cpp

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 two nodes — head and tail. The next part after the creation of a node is to join the nodes and create the linked list. Try to understand the code by allocating two to three nodes by above mechanism and you will get it.

We're Hiring. The picture representing the above structure is given below. And the picture representing the linked list is: So, if we have access to the first node then we can access any node of the linked list. Coding up a linked list You are now clear with the concepts of a linked list.

The linked list stores data in sequential storage, like arrays. Though the data are stored sequentially, the memory locations are not contiguous. Unlike an array, the linked list can store data of different data types.

The below diagram represents the linked-list structure. InsertNode : In this article, insertion is done at the end of the list. Follow the steps to insert a node in the linked list. To insert a new node traverse till the end of the list until NULL node is found. Create a new Node, and link the new node to the last node of the linked list.

DeleteNode : In this article, deletion is done using the index of the node. Follow the steps to delete a node: If the node to be deleted is the head node, store the head in temp variable. Delete temp. If the index of the node to be deleted is greater than the length of the list then return from the function.

Traverse till the node to be deleted. Delete the node, and link the previous node to the next node of the deleted node. Node int data.
