pseudo code algorithm to create a linked list

Header linked list are frequently used for maintaining polynomials in memory. The header node plays an important part in this representation, since it is needed to represent the zero polynomial. This representation of polynomial will be presented in the context of a specific
The utility of a header node in a linked list is to simplify the functions of adding and deleting elements in the list. If you have a pointer in memory that points to the first element, then you need to pass the address of that pointer, rather than the value of that pointer, to the routines for list manipulation, because that pointer would need to change if an element were added or deleted at the head of the list. If that pointer, however, points to a special element in the list which is actually the pointer to the head of the list, then you do not need to pass the address of the pointer - you can pass its value, and it will never change. This technique "wastes" the data portion of that first element.
Header file is a file which is meant to be included into another file during compilation. Examples: string.h, stdio.h, inttypes.h. Header pointer is a pointer to an object called header (for example header of a linked list).
Singly Linked list Each item in the list is called a node and contains two fields  Information field - The information field holds the actual elements in the list  Next address field- The next address field contains the address of the next node in the list. The entire linked list is accessed from an external pointer called the List. Doubly linked list is a collection of node. Each node contains three fields an info field that contains the information stored in the node. The left and right field that contains the address of the node on its left and right. The doubly linked list could be linear, circular and may have a header node.

You might look at the header record if the linked list has one. Better yet graduate to a btree and all these problems go away
Classification #1 - With a sentinel (header) element. - Without a sentinel (header) element. Classification #2 - Normal - Circular

In C programming, a double linked-list refers to a linked data structure that contains a set of links that have been linked sequentially.
It is true that a linked list is a collection of nodes.And a node contains data part and a link part which contains address of the next node.
A simple linked-list is an approach is to store the freelist of memory blocks, where each node of the linked list contains a pointer to a single free block in the memory pool.
A simple linked list is built out of nodes. Each node consists of two sections, data and a pointer. The data contains whatever information that this node of your list needs to contain, and the pointer contains the memory address of the next node in your list.
