Queue Operations in C: Essential Guide

Basic operations of a queue include:

1. Initialize the queue by creating an empty queue and setting up its parameters, such as the queue’s size and pointer.
2. Enqueue operation: Insert an element at the end of the queue, increasing the size of the queue by 1.
3. Dequeue operation: Remove an element from the head of the queue and return it, reducing the size of the queue by 1.
4. Accessing the front element: Returns the head element of the queue without removing it from the queue.
5. Get the last element (rear): Return the last element of the queue without removing it from the queue.
6. Check whether the queue is empty by determining if the size of the queue is 0.
7. Check if the queue is full (isFull): This involves checking if the queue is at its maximum capacity by comparing its size with its maximum capacity.
8. Clear Queue: Empty the queue by setting its size to 0.

The above are the basic operations of a queue, which can be expanded and modified according to actual needs.
