Write in C, and provide a Makefile

image text in transcribed

In this assignment, you will implement a program to show the performance of FCFS scheduling algorithm with I/O burst. Your program should get a file (e.g., "jobs.txt") as the command-line input, and read the contents of the file. This file contains a set of processes. For example, consider the file with the following content: \begin{tabular}{|l|} \hline 346:(45,15);(16,20);(80,10);(40,1) \\ 2547:(15,10);(60,15);(90,10);(85,20);(20,1) \\ 49:(30,15);(40,20);(5,15);(10,15);(15,1) \\ \hline \end{tabular} In this example we have 3 processes, each process is represented in a separate line. The general format of a line is as follows: The first token is the unique process id. After process-id you have a colon (:) delimiter. Then you will see a list of tuples separated by semicolons (;). Each tuple in parentheses indicates the next cpu-burst and io-burst lengths of the process. The cpu and io burst length in terms of milliseconds. If the last io-burst is 1, then it means that the process terminates without making an I/O. - Note that this input is just an example, I may use a different input file having a different content for testing your codes, but the format of the file will be same. ( Be careful on duplicate last line issue when reading from the input file) - You will assume that ; all the jobs arrive at the same time (t=0), the order of arrival is the same as the order of process-ids (i.e., smaller ids arrive earlier). the process never waits at the device queues and I/O starts immediately. The IDLE process is executed if no other processes are ready to run. First Come First Served (FCFS) Algorithm Implement FCFS scheduling policy. You should print the following a. Average turnaround time: The average of the turnaround times of all process b. Average waiting time: The average of the total waiting time for all processes. c. The number of times that the IDLE process executed. d. Print a HALT message in the end of processing. Submission Guidelines: You must implement this project in either C (120 points) or Java (over 100 points). In both cases you must provide a Makefile file for compiling your homework (if not provided
