if the queue contains one element then front end is equal to the rear end.
The queue is a linear data structure where operations of insertion and deletion are performed at separate ends also known as front and rear. Queue is a FIFO structure that is first in first out. Following are the types of queue: Linear queue Circular queue Priority queue Double ended queue ( or deque )
A queue is simply a FIFO i.e first in first out. In queue we've front and rear. Front is the initial or first location of the queue whereas rear indicates the last entry location in the queue. In the circular queue the location of front and rear will be the same IF the total space of the circular queue is utilized. Each element has its position no. for insertion , if we set the 5th element as the front element then after every insertion the ptr indicates the 5th element as front. in deletion, the fifth element is deleted every time it is the rear position. after deletion of an element the queue rotates and every time the rear indicates the 5th element of the circular queue. and every time the 5th location element is deleted.
In queue insertion takes place on rear end and deletion takes place on front end. INSERTION(QUEUE,N,FRONT,REAR,ITEM) :QUEUE is the name of a array on which we are implementing the queue having size N. view comlete ans at http://mcabcanotes.in/algorithm-to-perform-insertion-and-deletion-in-a-queue/
The queue is a linear data structure where operations of insertion and deletion are performed at separate ends also known as front and rear. Queue is a FIFO structure that is first in first out. A circular queue is similar to the normal queue with the difference that queue is circular queue ; that is pointer rear can point to beginning of the queue when it reaches at the end of the queue. Advantage of this type of queue is that empty location let due to deletion of elements using front pointer can again be filled using rear pointer.

Delete Front---- DQDELETE_FRONT(QUEUE, FRONT, REAR, ITEM) 1. [check for queue underflow] If FRONT<0, Then: Print: "Queue is empty", and Return. 2. ITEM = QUEUE[FRONT]; 3. Set FRONT = FRONT + 1. 4. Return. Delete Rear---- DQDELETE_REAR(QUEUE, REAR, FRONT, ITEM) 1. [check for queue underflow] If REAR<0, Then: Print: "Queue is empty", and Return. 2. ITEM = QUEUE[REAR]. 3. Set REAR = REAR - 1. 4.Return.
A circular queue is similar to the normal queue with the difference that queue is circular queue ; that is pointer rear can point to beginning of the queue when it reaches at the end of the queue. Advantage of this type of queue is that empty location let due to deletion of elements using front pointer can again be filled using rear pointer. There are 2 conditions for queue full if queue is implemented using arrays. First condition is Front = 1 and Rear = N Second condition is Front = Rear + 1

A queue is a line, as standing in line to get a ticket, or standing in line to buy food. Get back in queue, you! Look at that queue. I've never seen a longer queue in front of the ticket box!
It means staying in a line (or queue) of people: not pushing, not jumping in front.
A queue is simply a FIFO i.e first in first out. In queue we've front and rear. Front is the initial or first location of the queue whereas rear indicates the last entry location in the queue. In the circular queue the location of front and rear will be the same IF the total space of the circular queue is utilized. Each element has its position no. for insertion , if we set the 5th element as the front element then after every insertion the ptr indicates the 5th element as front. in deletion, the fifth element is deleted every time it is the rear position. after deletion of an element the queue rotates and every time the rear indicates the 5th element of the circular queue. and every time the 5th location element is deleted.

No, you queue up in the same queue with everyone else, but you can still request the front row (NICELY!) and you'll more likely than not get it.

The queue is a linear data structure where operations od insertion and deletion are performed at separate ends also known as front and rear. Queue is a FIFO structure that is first in first out. Whenever a new item is added to queue, rear pointer is used. and the front pointer is used when an item is deleted from the queue.
