c++ class question

[saiz66]

Hi. I basically have to create a Hospital program. I created a Patient class which holds each of the patient's priority, treatment time and so on. Well I made those variables private and created a getPriority, setPriority methods in public. Those look like this:

void setPriority(int priority);
int getPriority();

That seems to be fine. Then I have to insert into a priority queue, which has already been created by my professor. I have then created a Priority Queue:

PQueue <Patient> PQ;

Ok. then I inserted the patient class into the priority queue:

PQ.Insert(patient[i]);

And this is where I get confused. I want to get the patients with the highest priority and print them out. The function to get the highest priority is:

int DeleteMin ( Etype & E );

I understand that it returns the highest priority in Etype & E where the Etype is class Patient. I tried this:

PQ.DeleteMin(patient[i]);

I am confused. Do I need to create a new class. Anybody can help me out? Thanks in advance!

C++ as it is does not know what PQueue is.
Therefore I don't know how DeleteMin() is defined. But now I assume that DeleteMin() is a member of PQueue.

huh? Sorry I did not really understand that. DeleteMin is a function to return the highest priority into an Etype & E as a reference. I know how to do this if the Etype was an integer. But I don't know how to return it into my patient's class' set method. If for example I wanted to return the highest priority I would simply just PQ.DeleteMin(int priority); and now the highest priority will be deleted and sent into the integer priority. but my Etype is a class and not an integer. In my class I have a private integer called priority. I have a setPriority and getPriority method basically just setPriority(in priority); I have made a priority queue of Patients which is a class I created. I am confused on what to do next. I want to be able to know which patient has the highest priority and print that out.

Just post the code.
And where do I obtain the PQueue library?
