#LINKED LIST STACK C CODE#

Once the user enters the position, it checks if it is the first position, if yes it assigns ptr to start and moves the start pointer to next location and deletes ptr. If it is not empty it asks the user for the position to be deleted.

In the deletion process, it first checks if the list is empty, if yes it exists.

Here’ s the snippet of code to delete a node from the linked list. We then run a loop till ptr is null and print the data element for each node, until ptr is null, which specifies the end of the list. In the next part, we assign the start value to ptr. In the display function, we first check if the list is empty and return if it is empty. In a similar way, there is code given for inserting at the beginning, inserting at the end and inserting at a specified location. We then assign ptr->next the address of temp. Otherwise, we traverse to the last point where the data has been added.įor this, we assign ptr the start value and traverse till ptr->next= null. If the start of the list is null, then we assign temp to the start pointer. There is a start pointer holding the start of the list. We take the value that is needed to be added in the linked list from the user and store it in info part of the temp variable and assign temp of next that is the address part to null. void create()įirst, two pointers are created of the type node, ptr, and temp. This is the basic way the linked list is created. Create Functionįirst, there is a create function to create the linked list. Let’s take a look at each of these functions. Next, we have different functions that need to be solved. The input is then sent to the switch case and based on user input.īased on what input is provided the function will be called. In the main function, we take input from the user based on what operation the user wants to do in the program. These functions are called by the menu-driven main function. There are various operations that can be done on a linked list, like: In the structure, we have a data variable called info to hold data and a pointer variable to point at the address. This is done to give the compiler an idea of how the node should be. A linked list structure is created so that it can hold the data and address as we need it. The first part of this code is creating a structure. Printf('nThe deleted element is:%dt',ptr->info ) Printf('nEnter the position of the node to be deleted:t') Printf('nThe deleted element is:%dt',ptr->info) Printf('nThe deleted element is :%dt',ptr->info) Printf('nEnter the data value of the node:t') Printf('nEnter the position for the new node to be inserted:t') Printf('nEnter the data value for the node:t' ) Printf('nEnter the data value for the node:t') Temp=(struct node *)malloc(sizeof(struct node)) Printf('n 8.Delete from specified position n') Printf('n 5.Insert at specified position n')

The following code will show you how to perform operations on the list. First, we create a list, display it, insert at any location, delete a location. Let’s try to understand them with the help of an example program. There are multiple functions that can be implemented on the linked list in C. This is how a linked list is represented. In the example, the number 43 is present at location 1000 and the address is present at in the previous node. The most popular types of a linked list are: The Linked List is like an array but unlike an array, it is not stored sequentially in the memory. The disadvantage is that to get to a node, we must traverse to all the way from the first node to the node that we require. The size of the linked list is not fixed, and data items can be added at any locations in the list. Every linked list has two parts, the data section and the address section that holds the address of the next element in the list, which is called a node. What is Linked List in C?Ī Linked List is a linear data structure. In this article, let’s see how to implement a linked list in C. A linked list is a linear data structure, made of a chain of nodes in which each node contains a value and a pointer to the next node in the chain.

After arrays, the second most popular data structure is Linked List.
