    Well for a circular queue you don't delete the bottom, you remove the head ( or top if you want to use that terminology ). Let me help you read up on this.

    Then it wouldn't be a circular queue now would it? Here is some suggested reading for this.

    If deleting can be done anywhere, then it's just a linked list and not a queue.

    What do you mean by a circular queue?
    Is it a circular buffer, or a linked-list where the last item points back to the first?
    If it were truly a queue, then you would not remove it from the middle, you would wait until it reaches the head and then if upon popping the item off, you find that you don't want it afterall, then and only then do you throw it away.
