Array-based Circular Queue Implementation

  1. Initialize the queue with a fixed-size array, head and tail pointers, and size counter.
  2. For enQueue, check if the queue is full. If not, insert the element at the tail and increment the tail pointer (modulus the capacity).
  3. For deQueue, check if the queue is empty. If not, remove the element from the head and increment the head pointer (modulus the capacity).
  4. For Front, return the element at the head pointer if the queue is not empty.
  5. For Rear, return the element at the tail pointer if the queue is not empty.
  6. For isEmpty, check if the size is zero.
  7. For isFull, check if the size is equal to the capacity of the queue.
