It is a structure that contains two forms i.e, data and next pointer. Data part in a node contains value and the next part contains the address of the next node.<\/li>\n\n\n\n<li>Next Pointer : Next pointer in a linked list data structure points the next node in the arrangement. The next pointer of the last node in the linked list points to NULL to avoid undefined behaviour.<\/li>\n\n\n\n<li>Head : Head is also a pointer in a linked list but it points to the first node of the entire list.<\/li>\n<\/ol>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"811\" height=\"307\"
