C

C is a programming language designed by Dennis Ritchie at Bell Labs. C is very widely used, straightforward, and can be compiled to a number of platforms and operating systems. C is an imperative language, with a small number of keywords and a large number of mathematical operators. C is also a very low level programming language, which means it can communicate directly with hardware.

This is a simple implementation of a circular linked-list in C. Circular linked-lists are a type of linked-list where the last node points to the first node. This is useful for implementing queues and stacks. This implementation is a doubly linked-list, meaning that each node has a pointer to the next node and a pointer to the previous node.
