c++ program for round robin

[dhaya]

i need a program urgently for round robin schedulng algorithm using circular linked list implementation..
please send a program using c++...

post the prg to my mail id..

I did this in my C++ programming assignment.

I just used a STL list and poped from the front
and pushed to the back.

why dont u send the program to me as an attachment to my mail id

What is preventing you from doing this yourself?

A coupe of reasons

a. Rashakil Fol's post
b. it takes in total 3 lines of code

value = myList.front();
myList.pop_front();
myList.push_back(value);

you should prolly check to see that the list isn't empty first and of corse make the list and varible value , you can then use value, If your doing this in muliple parts of your program.

Its prolly advisable to make a function to do this for you, How far you want to go with this is upto you ( make a template if you will so it can take any type of varible and spit out a value.

If it is infact for an assignment and they havent told you to use any of the standard template libary, they may infact not want you to and if that is the case I would try the following.

1. Create a Linked list

Use an object or a struct ( what ever takes your fancy ) with a varible containing the data and a pointer to another struct of the same type.

Now if your doing a round robin kinda algorithem you may want the lists to be in a nice loop, so insted of having a start and an end you don't.

then make some kinda way of remembing where you are in the list (another pointer to a element) and then change that when you access a value

imLookingHere = imLookingHere->nextInList;

or what not.

then you just have to worry about attaching things in etc. anyway check out some reasources on the web

Don't mean to be a dick, but I don't like people asking me for all the code I have written for a particular assignment, when they have not shown any effort thus far. Whenever you have to do a programming assignment, start it way ahead of time and work on it a little every day.

I posted a reply in the above thread that tells you how I did it. I don't know if this will help you or not. I did the assignment in order to keep track of a bunch of things like turnaround time and context switches. My implementation also is formatted so that I could write a gannt chart output function if I so desired.

Haven't been on here for ages....

cna i get a mail of the code please.

No.

But thanks for bringing me back to DaniWeb :)
