c program for srtf cpu scheduling algorithm program

Write a program to generate and print another tuple whose values are even numbers in the given tuple (1,2,3,4,5,6,7,8,9,10).Categories C, Operating Systems Tags C, Operating Systems Thus priority scheduling program was executed Successfully. Printf(' Avg Turn Around Time = %.2f ',avg_tat) Printf(' Average Waiting Time = %.2f',avg_wt) Printf(' Process BT WT TAT') Printf(' Enter Burst Time and Priority For ') Printf('Enter Total Number of Process:') Int i,j,n,bt,p,wt,tat,pr,total=0,pos,temp Suppose the ready list contains the processes as shown in the table. STEP 10- In float average turn around time equal to total divided be n value, and print the average waiting time and average turn around time.STEP 8- Print the value process burst time waiting time and turnaround time.STEP 9- tat equal to bt add the wt, tot add or equal to tat,and print the value p,bt,wt andtat.STEP 7- Waiting time for first process is zero, calculate waiting time, average waiting time.STEP 6- if pr less than pr, pos=i and create the temporary file and equal to the bt, bt equal to bt, btequal to temporary, temporary equal to p, so p equal to p and p equal their temporary file.STEP 5- Print the i+1, Burst time and Priority time in the P=i+1.STEP 4- Sorting burst time, priority and process number in ascending order using selection sort.STEP 3- Print the total number of process in the n.STEP 2- Declare the value of bt, p, wt, tat, pr, I, j, n, total=0, os, average waiting time and average turnaround time.Example Input-: processes = P1, P2, P3Īverage turn around time = 14.To Write a Program Using C to Implement the Priority Scheduling. Gantt chart showing the waiting time of processes P1, P2 and P3 in the systemĪs we have taken arrival time to be 0 therefore turn around time and completion time will be same. Let’s say, there are four processes arriving in the sequence as P2, P3, P1 with their corresponding execution time as shown in the table below. Waiting Time = turnaround time – burst timeįirst Come, First Served (FCFS) also known as First In, First Out(FIFO) is the CPU scheduling algorithm in which the CPU is allocated to the processes in the order they are queued in the ready queue.įCFS follows non-preemptive scheduling which mean once the CPU is allocated to a process it does not leave the CPU until the process will not get terminated or may get halted due to some I/O interrupt. Waiting Time is the difference between turnaround time and burst time Turnaround Time = completion of a process – submission of a process Turnaround Time is the time interval between the submission of a process and its completion.

What is Waiting Time and Turnaround Time? The task is to find the average waiting time and average turnaround time using FCFS CPU Scheduling algorithm.

P1, P2, P3.,Pn and their corresponding burst times. We are given with the n number of processes i.e.
