void FCFS(program pro[],int num){ printf("进程到达时间服务时间开始时间完成时间周转时间带权周转时间\n");sortWithEnterTime(pro,num);//按照到达顺序排序 programQueue* queue =(programQueue*)malloc(sizeof(programQueue));Queueinit(queue);//初始化进程就绪队列 EnterQueue(queue,&pro[0]);//将第...
对于先到先服务调度策略FCFS的实现在函数fcfs中实现,通过先进先出的队列可以实现,将新的线程任务队列节点插入到调度队列的尾部即可。 对于抢占式的最短作业优先调度策略的实现在函数pem_sjf_push中实现,抢占式有机会插在已经存在的头结点前面,作为新的头结点被调度器调度执行,只需要在调度队列中找到WCT恰好小于自己的...

c++中的explicit关键字用来修饰类的构造函数,表明该构造函数是显式的,在某些情况下,我们要求类的使用者必须显示调用类的构造函数时就需要使用explicit,反之默认类型转换可能会造成无法预期的问题。 protected控制的是一个函数对一个类的成员(包括成员变量及成员方法)的访问权限。protected成员只有该类的成员函数及其派生类...
先来先服务(FCFS):按照任务到达的顺序进行调度,先到先得。这种方法简单易实现,但可能导致较长作业阻塞短作业。 短作业优先(SJF):优先执行估计运行时间最短的作业。这种方法可以最小化平均等待时间,但可能导致长作业饥饿。 轮转调度(RR):为每个任务分配一个固定的时间片,任务按照顺序轮流执行。这种方法可以保证公平性...

Fair locks in Java are a type of lock that ensures threads acquire the lock in the order they requested it, adhering to the first-come, first-served (FCFS) principle. This helps in preventing thread starvation, where certain threads might never acquire the lock due to continuous acquisition ...

Your C program will perform the following tasks in order based on the given input file: 1. Ready queues will be executed in the order of their queue number (q 1, q 2, etc.) 2. CPU scheduling algorithms FCFS, SJF, and RR will be applied on each ready queue ...
