Question

we need to make a c program using multi process approach , one process will initialize 7 processes the first one of them will create the other 6 processes each one of them will do one of this algorithms fcfs , sjf,srtf,rr with quantum = 5 Preemptive Priority Scheduling, with aging; where priority is decremented by 1 if the process remains in the ready queue for 5 time units. 6- Non-preemptive Priority Scheduling, with aging; where priority is decremented by 1 if the process remains in the ready queue for 5 time units and it must schedule them and keep updating the status (and printing it ) like ready , waiting,executing,etc. of the processes in this set of processes : Process Arrival Time Burst Time Comes-back-after Priority P1 0 10 2 3 P2 1 8 4 2 P3 3 14 6 3 P4 4 7 8 1 P5 6 5 3 0 P5 7 4 6 1 P7 8 6 9 2 the prgoram must print the results which are : the Gantt chart, average waiting time, and average turnaround time. , note that Burst Time is the maximum duration allowed at a single go at a CPU (actually running on a CPU) for that process. You might use the term time slot. When a Process is allowed to run, the Burst Time timer/counter is reset to 0, and then incremented as the clock ticks, and if the Burst Time is met then the Process is definitely not completed, and it had to be interrupted/stopped/suspended due to the Burst Time limit, rather than being finished. So you have to implement the project in this way : You are required to simulate the CPU schedule for a period of 200 time units such that : Once each process is done processing its “Burst Time”, it goes to the waiting queue, then “Comes back” to the ready queue after the time shown. For each of the following scheduling algorithms, your program must show the Gantt chart, average waiting time, and average turnaround time' so a process might run more than one time . you have to keep executing each algorithm for a 200 time units i need a fully implemented code because there is no time do everything as required Dont use ai because it doesnt work
