I'm almost done with this project i just need help debugging my code. Seeing as the project code is to long to put in a question ill post each header and source file on GitHub and give links.
https://github.com/Bobbyhoff/CPU-Scheduling-SJF-FCFS-MLFG-
The problem im having is my printStatsSJF function(from scheduling.h) is getting a divide by 0 error and messing up my results. and im pretty sure thats why the FCFS and MLFQ results arent printing when i debugg. The FCFS results printed above are given by the professor. my results for FCFS and MLFQ will not print. only SFJ will print results.
If you need any addition information when helping me please comment and ill try my best to help!
Implement the following 3 CPU scheduling algorithms - . Simulate and evaluate each with the set of eight processes below 1. FCFS non-preemptive (results provided) 2. SJF non-preemptive 3. MLFQ Multilevel Feedback Queue (absolute priority in higher queues) Queue 1 uses RR scheduling with Tg- Queue 2 uses RR scheduling with Tq-11 Queue 3 uses FCFS All processes enter first queue 1. If time quantum (Tq expires before CPU burst is complete, the process is downgraded to next lower priority queue. Processes are not downgraded when preempted by a higher queue level process. Once a process has been downgraded, it will not be upgraded Assumptions: 1. All processes are activated at time 0 2. Assume that no process waits on I/O devices 3. After completing an IO event, a process is transferred to the ready queue 4. Waiting time is accumulated while a process waits in the ready queue Process Data process goes {CPU burst, IO time, CPU burst, IO time, CPU burst. time. last CPU burst) .. .
