you are to simulate some typical functions of an operating system. An operating system queues jobs waiting to be executed according to a priority scheme, often related to user status. Processes (jobs) are placed on a queue and are scheduled once the resources become available. The following is the scheme that this operating system will follow to queue user processes that are waiting to be executed. System users have relative priorities based on their user ID numbers: Users 0 - 99 have highest priority Users 100 - 199 have next to highest priority Users 200 - 299 have next highest priority ….. ….. ….. Users 800 - 899 have next to lowest priority Users 900 - 999 have lowest priority Within each priority group the jobs will execute in the order in which they arrive into the system. If there is a highest priority job queued, it will execute before any other job; if not, if there is a next to highest priority job queued, it will run before any lower priority job; and so on. This assignment consists of the following three parts: 1. Process Placement Manager: Receives a user ID and a token, representing the job to be executed, and adds the token to the appropriate queue for that user priority level. 2. Process Dispatching: Returns the token for the highest priority job (next job to be executed) that is queued for execution and removes the job from the queue. 3. Maintenance Notification: Notifies users when their waiting jobs (contents of queues) are to be removed from the system due to routine maintenance. Messages are displayed to all users with queued jobs according to priority levels. The highest priority users should be notified first ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. Complete copyrights to all work purchased. This is needed no later than april 10, 2002 ## Platform you could use any compiler Visual C++ prefered.
