There are many variants of linked lists such as a circular linked list in which the last node contains the address of the first node, doubly linked lists in which every node contains pointers to previous and next nodes and circular doubly linked lists which is a circular doubly-linked list.
Arrays should be used when the size of data to be stored is known in advance and does not change frequently. A disadvantage of a linked list is that we can not access every element in constant time as in an array. Understanding linked lists will help you to learn the tree data structure.

So, if we have access to the first node then we can access any node of the linked list. One thing you should notice here is that we can easily access the next node but there is no way of accessing the previous node and this is the limitation of singly linked list. You are now clear with the concepts of a linked list. The first part is to create a node structure. 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.
