#CPU Scheduler for: FCFS, SJF with preemption, RR (with specified time quantum), and Priority with preemption
Instructions for CPU Scheduling
Authors: James Lopez
Chantal Murdock

Read these instructions carefully.

For FCFS, Preemptive SJF and Priority:

1. FIRSTLY! Open datagen.cpp and run the program to generate random
number of burst time and arrival time of each process.
The values are generated in a text file called datagen.txt.

2. If you want to do FCFS first, open FCFS.cpp and run the
CPU scheduling for FCFS. The values are outputted in a
text file called FCFS_ouput.txt

3. If you want to do Preemptive SJF first, open SJF.cpp
and run the CPU scheduling for Preemptive SJF.
Since it has 10000 process, you have to wait like 5 mins to complete the run.
The values are outputted in a text file called SJF_ouput.txt

4. If you want to do Preemptive Priority first, open Priority.cpp
and run the CPU scheduling for Preemptive Priority.
Since it has 10000 process, you have to wait like 5 mins to complete the run.
The values are outputted in a text file called Prio_ouput.txt

Note: Since it has 10000 process, you have to wait like 5 mins to complete the run
for Preemptive SJF and Preemptive Priority.

For Round Robin:

1. FIRSTLY! Open datagenRR.cpp and run the program to generate random
number of burst time and arrival time of each process.
The values are generated in a text file called datagenRR.txt.

Note: Since this algorithm takes a lot of time to process 100-10000 processes (It took hours and even days)
We only generate 15 processes (It only took 20-30 seconds.)

2. Open RoundRobin.cpp and run the CPU scheduling for Round Robin.
The values are outputted in a text file called RR_ouput.txt
