C语言实现了先来先服务(FCFS),最短作业优先(SJF),最高响应比优先(HRRF) ,优先级调度(HPF),抢占式高优先级(PHPF)
process ID ordering breaks any “ties” regarding scheduling). The CPU scheduler dispatches a ready process as designated by the given scheduling algorithm, and the process runs. When a context switch occurs, add tcs, the overhead for performing the context switch. ...
program must compute a schedule for the processes using the Round Robin algorithm and print the schedule on the screen. Here is an example of what running the program must then look like (where 3, 24, 3, 3, and 4 are inputs typed by the user on the keyboard): === Enter the number...

for my assignment, we were given a program that would simulate a FCFS scheduling algorithm in C, and we were to modify it twice to simulate SJF and RR (Quantum 4) and compare the mean response times for each. I have completed the SJF version, but am having issues with...
