Objective:

To calculate the timing parameters of batch processes based on different scheduling algorithms by using C language.

Specification:

The program mimics the execution of different processes under different scheduling algorithms. The simulation maintains a table that reflects the current state of the system, based on choosing from a menu of choices, where each choice calls the appropriate procedure, where the choices are:

$1)$ Enter parameters

$2)$ Schedule processes with FIFO algorithm

$3)$ Schedule processes with SJF algorithm

$4)$ Schedule processes with SRT algorithm

$5)$ Quit program and free memory

Assignment:

$$ Create a table to record the status of different processes based on the following parameters:

o id: the unique identifier of the process $[$auto$-$generated, starting from $0$do not

input the id from the user$]$

o arrival: the point in time i$.$e$.$ when the process enters the ready list to be executed by the CPU $[$input from the user$]$

o total$\_$cpu: the amount of CPU time the process will consume between arrival and

departure $[$input from the user$]$

o total$\_$remaining: the amount of CPU time remaining for a process to complete $[$used

for SRT scheduling only$]$

o done: a flag that indicates whether the process has been successfully completed $(1)$ or not $(0)$

o start$\_$time: the time when the process has begun being executed by the CPU

o already$\_$started: a flag that indicated whether the process has already begun $(1)$ or

not $(0)[$used for SRT scheduling only$]$

o end$\_$time: the time when the process has been completed by the CPU

o turnaround$\_$time: the sum of the total CPU time and the waiting time $($alternatively:

the difference between the end time and the arrival time$)$

$$ Calculate the values for the start$\_$time, end$\_$time, and turnaround$\_$time for each process based on the selected scheduling algorithm.

What NOT to do:

$$ Do NOT modify the choice values $(1,2,3,4,5)$ or input characters and then try to convert them to integers$--$the test script used for grading your assignment will not work correctly.
