Circular Queue introduction | Circular Queue in Data Structure | Circular Queue using Arrays in C |

A circular queue is a linear data structure that follows the FIFO (First In First Out) principle but connects the last position back to the first position, forming a circle. This design efficiently utilizes space, allowing for continuous use of the queue without needing to reset or move elements when items are dequeued.
Key Characteristics:
Fixed Size: A circular queue has a predefined maximum size.
Two Pointers: It typically maintains two pointers: front (for dequeuing) and rear (for enqueuing).
Wrap-Around: When the rear reaches the end of the queue, it wraps around to the beginning if there’s space available.
Applications:
Managing resources in operating systems.
Implementing buffering systems in streaming.
Simulating round-robin scheduling in task management.
Example Operations:
Enqueue: Add an element to the rear of the queue.
Dequeue: Remove an element from the front of the queue.
Peek: View the front element without removing it.
Benefits:
Efficient space utilization.
Eliminates the need for shifting elements, as in a traditional queue.
