CPU Scheduling Simulator
### Description
`C++ Program` to simulate different `Operating System Scheduling Algorithms` using dup/dup2, fork, exec, and inter-process communication primitives.
### Algorithms Implemented
- Round Robin (RR)
- First Come First Serve (FCFS)
- Shortest Job First (SJF)
### Manual
1) Use the following command to `Compile the Code`:
```
g++ 5_state_model_simulator.cpp
```
2) Use the following command to `Run the Code`:
```
./a.out
```
3) You can `Change Processes` in the files named as Sample_1_RR.txt, Sample_2_FCFS.txt, Sample_4_SJF.txt. Its format is given below:
- First line indicates scheduling algorithm to perform.
- Second line indicates quantum for RR.
- Further lines indicate process number, its arrival time, and its cpu burst required.
4) You can see `Final Output` i.e, throughput, average waiting time, average turnaround time in the file named as `processes_stats.txt`
