Breaking into the programming world might be slightly more difficult than expected. If one wants to make it to a product-based software company in the future, knowledge of data structures and algorithms is essential. In our day-to-day lives, we use a variety of different data structures.

One of the most popular data structures used throughout the world of computer science is the linked list. A linked list has many problems on its own, however. One needs to store a pointer to the head of the linked list carefully somewhere and store its value inside another pointer before manipulating the linked list. To resolve this issue, we use two slightly modified versions of the linked list: the doubly linked list and the circular linked list.

A circular linked list is a linked list where all nodes are connected to form a circle. Generally, the last node of the linked list has a NULL in the address field, but a circular linked list has the address of the head node in the address field of the last node.

If you are not up-to-date with what a linked list is; it is a data structure that allows allocation of memory dynamically that is, depending on our needs.

It is made up of nodes that have two main components:. A linked list starts with a head node — the first node in the list. Nodes are appended one by one to the list starting from the head. Circular singly linked list is a type of data structure that is made up of nodes that are created using self referential structures. Each of these nodes contain two parts, namely the data and the reference to the next list node.

Only the reference to the first list node is required to access the whole linked list. This is known as the head. The last node in the list points to head or first node of the list. That is the reason this is known as a circular linked list. In the above program, the structure Node forms the linked list node.
