本程序包括先来先服务调度、短作业（进程）优先调度、优先权调度三种算法。用C语言实现，执行时先输入进程数（到达时间、运行时间、优先权由随机函数产生），在主界面选择算法（可用函数实现），执行，显示结果。-procedures including the first-come first-service scheduling, short operations (process), priority scheduling, priority scheduling algorithm three. C language, the implementation process input (arrival time, the running time, priority generated by the random function). the main interface selection algorithm (available Function), implementation, the result will be displayed.
