hi,
im working with the queue class but not allowed 2 use the collections namespace, ok thats fine. paitent is the name for objects i want to queue. heres my paitent class

public class paitent
        {
            private string name;
            private string NHSW;
            private paitent next;
        }
        public string name
        {
            get { return name; }
            set { name value; }
        }
        public string NHSNnumber
        {
            get {return NHSN;}
            set { NHSN value; }
        }
        public paitent next
        {
            ///////////// here i want to combine name and NHSNnumber\\\\\\\\\\\
        }

im thinking i need a for loop. does any one know of a good web page where i can see some
queues to help.

any suggestions would be awesome, thanks

Your queue class should be independent of your patient class. A patient doesn't have a Queue, a Queue contains a patient.

What does a queue need? A way to add members to the queue, a way to remove members from the queue and a way to see if there is anyone in the queue. Implement those methods and you'll have your Queue class.

Use the generic Queue type available in .NET
Something like:

Queue<patient> PatientsWaiting = new Queue<patient>();
patient P = new patient();
P.Name = "Smith";
PatientsWaiting.Enqueue(P);

Use the generic Queue type available in .NET

You didn't read the original problem, i.e. the line that says "I'm not allowed to use the collections namespace".

Yes, I know, my bad.
I was in fact referring to your answer, to separate the patient class from the Queue class. Thought mayby an small snippet on how it can be done, might help.

thanks for responding fellas. i have the paitent class sorted and im sure it will work. i was just hoping someone had came across a web page, but ill see how we go

so im just going to use stack with my queue. the only thing im having problems with is with enqueue.im tryng to gt new patients on the stack,iv tried a few ways to do it but same errors. i cant see any other problems other than that, but if there are let me know and ill debug. thanks heaps guys
