// 计算每个进程的等待时间并输出 for(int i = 0; i < n; i++) { printf("%d\t\t %d\t\t %d\t\t ", processes[i].pid, processes[i].arrival_time, processes[i].burst_time); int wait_time = (i == 0) ? 0 : processes[i - 1].burst_time; printf("%d\n", wait_time); }...
Turn Around Time=Completion Time-Arrival Time Waiting Time=Turn Around Time-Burst Time 在第一种情况下,过程P1到达队列中的第一个;该过程的突发时间最高。由于调度算法是FCFS,因此CPU将首先执行进程P1。 在此时间表中,系统的平均等待时间将非常长。那是由于车队效应。尽管其他进程P2,P3的突发时间非常短,但它们...
Now let us try to understand this further with the help of an example. Suppose there are four processes with process ID'sP1,P2,P3, andP4and they enter into the CPU as follows: Process IDArrival Time (milliseconds)Burst Time (milliseconds) ...
We can calculate the Turnaround time by Turn Around Time = Completion Time - Arrival Time.Calculate the waiting time by the formula: Waiting Time = Turn Around Time - Burst Time.In the first phase, the process P1 arrives at the first in the queue. The process P1 has the highest burst ...
