In computer science, a queue is a particular kind of abstract data type or collection in which the entities in the collection are kept in order and the principal (or only) operations on the collection are the addition of entities to the rear terminal position, known as enqueue, and removal of entities.
yes,cursor implementation possible in priority queue.
For the Complete Implementation of Circular Queue Check out www.codeuniverse.tk
the priority queue is which depends on the data stored.in which their priority is maintained by checking the forth coming values stored in the queue
yes
The following are operations performed by queue in data structuresEnqueue (Add operation)Dequeue (Remove operation)Initialize
There are many ways to reverse the order of the elements in a queue. Provided that you have access to the implementation of the queue, it is of course easy to read the elements from the tail end rather than the front end, thus reversing the elements. However, considering the queue as a black box, and assuming the queue only allows for its characteristic operations (removal of head element, addition to tail), the best method to reverse the elements in a queue to engage a stack. You'd remove the elements from the queue (always reading the head of the queue), and push each element onto the stack. When the queue is empty, you reverse that process: pop each element from the stack until it is empty, and add each element in this order to the end of the queue. Your queue will have the exact same elements as in the beginning, but in reverse order. The exact implementation of this in C, or in any other programming language, is trivial, but the exact source code depends on the implementation of queue and stack containers. Following is pseudocode: Queue<Item> reverse (Queue<Item> queue) { Stack<Item> stack; Item item; while (queue.remove(&item)) { stack.push(item); } while(stack.pop(&item)) { queue.add(item); } return queue; }
Queues are commonly implemented for abstract routines and data access structures. In languages using object-orientation, they may be featured as classes. Some methods for implementation include circular buffers and linked tests.
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.
In programming a "pipe" usually refers to a connection to a data source (aka a database). The difference between a queue and a pipe is that a queue usually caches some data from the data source while a pipe is just a connection to the data source.
1. ios functions returns value while manipulators does not. 2.we can not create own ios functions while we can create our own manipulators. 3.ios functions are single and not possible to be combined while manipulators are possible to be applied in chain. 4.ios function needs <iostream> while manipulators needs <iomanip> 5.ios functions are member functions while manipulators are non-member functions.
Queue is a data structure which is based on FIFO that is first in first out. Following are the types of queue: Linear queue Circular queue Priority queue Double ended queue ( or deque )
I meant to say Digidesign not avid in my question. Thank you
