Implementing a Queue in C using Arrays: A Step by Step Guide

When you add an element add it at position of last pointer.1You can also implement a queue with a circular array. It follows the principle of “First in, First out” (FIFO), where the first element added to the queue is the first one to be removed. In some applications, it is necessary to track more than just one tag, and this allows you to do just that. As a commenter wrote before me, the TX_FIFO[tx_put_itr & (TXFIFOSIZE – 1)] = data; loops the output. Just implement a doubly-linked list, holding the pointer to the last item in the list. Use the end of the array to represent the top of the . I need a simple FIFO queue with only 2 elements in order to use the push and pop utilities: I am already aware of the fact that I could implement my own class to perform this kind of . // Demonstrated with void pointers and no memory management.

If you have large data, then a type of ring buffer makes sense. // This is because the head and tail pointers are only written by the producer and consumer respectively. Basically a queue.2Wouldn’t this just be a standard linked list, except you only define functions to pull off the head element and push stuff onto the tail element? Y.Just make a regular array and maintain two pointers to point first and last position in array. So, the array will always be full before it reaches the FIFO function, then the FIFO will remove the oldest array, move all of the arrays up by one and then add the newest array to the other end. The size is always power of 2 (8, 16, 32, 64, 128 etc).
