A structure is defined, called a node, that consists of two members: an integer and a pointer called next. I am creating a circular linked list comprised of integer numbers, which is why I have taken an integer member. However, you can use any number of members you want, as well as any data type.

A menu is displayed on the screen that shows three options: 1, to add elements to the circular linked list; 2, to display elements of the circular linked list; and 3, to quit. Obviously, the first step is to add elements to the circular linked list. Let's assume that the user enters ...
