操作系统：模拟磁盘调度算法

课题要求：●建立相应的数据结构

●在屏幕上显示磁盘请求的服务状况

●时间的流逝可用下面方法模拟：

（a）按键盘，没按一次可认为过了一个时间单位

（b）响应WM_TIMER

●将一批磁盘请求的情况存磁盘文件，以后可以读出并重放

●支持算法：FIFO，SSTF，SCAN，CSCAN，FSCAN

-Operating Systems: simulation of disk scheduling algorithm subject requirements: ● the establishment of the corresponding data structure displayed on the screen ● disk status of the requested service ● time simulation can be used the following methods: (a) by the keyboard, not by one that had a time units (b) in response to a number of disk WM_TIMER ● request keep the disk files, then you can read and playback ● support algorithm: FIFO, SSTF, SCAN, CSCAN, FSCAN
