C Program to Simulate Round Robin CPU Sceduling Algorithm

The round robin CPU scheduling algorithm is simulated using C program. The time slice or time quantum is read from the user.

Program:

#include<stdio.h>
struct process{

C Program to Simulate Priority Scheduling CPU scheduling Algorithm

The following C program implements Simulation of  priority scheduling (CPU Scheduling algorithm). Each process or job is given a priority. The priority is represented using a positive integer. The priority increases as the value of the integer decreases.

Program:

#include<stdio.h>
struct process{

Simulation of Shortest Job First (SJF) CPU scheduling algorithm in C Language

This is a C program to simulate Shortest Job First (SJF) CPU scheduling algorithm. In Shortest Job first CPU scheduling algorithm, the process with  shortest CPU burst time is executed first. The following program is to simulate non preemptive SJF scheduling. Preemptive SJF CPU scheduling algorithm will be discussed in another post.

Program:

#include<stdio.h>
struct process{
int burst,wait,no;
}p[20]={0,0};

Simulation of FCFS CPU Scheduling Algorithm in C

This is a C program to simulate First come first served (FCFS) CPU scheduling algorithm. First come first served algorithm serves each processes (or jobs) in the order of arrival. The process with lowest arrival time is executed first.

Program:
#include<stdio.h>
struct process
{
int burst,wait;
}p[20]={0,0};
