Write a C Program to implement Deque using circular array. Here’s simple Program to implement Deque using circular array in C Programming Language.


What is Queue ?


Queue is also an abstract data type or a linear data structure, in which the first element is inserted from one end called REAR, and the deletion of existing element takes place from the other end called as FRONT.

This makes queue as FIFO data structure, which means that element inserted first will also be removed first.


Basic Operations : :


  • enqueue() − add (store) an item to the queue.
  • dequeue() − remove (access) an item from the queue.
  • peek() − Gets the element at the front of the queue without removing it.
  • isfull() − Checks if the queue is full.
  • isempty() − Checks if the queue is empty.

Below is the source code for C Program to implement Deque using circular array which is successfully compiled and run on Windows System to produce desired output as shown below :
