Queue<Int32> qu = new Queue<int>(); You can call qu.Enqueue(); function to insert value into your queue. You can call qu.Dequeue(); function to delete item from your queue. It will delete the first item of the queue what you have inserted. Now in this program I have inserted tw...
In a stack, the insertion and deletion of elements happen only at one endpoint. The behavior of a stack is described as “Last In, First Out” (LIFO). When an element is “pushed” onto the stack, it becomes the first item that will be “popped” out of the stack. To reach the o...
Queue in C is a data structure that is not like stack and one can relate the behavior of queue in real -life. Unlike stack which is opened from one end and closed at the other end which means one can enter the elements from one end only. Therefore, to overcome the scenario where we...

Then I thought, if Linux/Unix can have/dev/nulland Windows hasNULfor commands and/or scripts then why shouldn’t MQ have aNULL.Qfor throw away messages. This is really easy to implement in MQ with a simple piece of C code called ‘EmptyQ’. ...
