、缓冲管理（双缓冲/循环缓冲/缓冲池）
要求：
（1）模拟双缓冲、循环缓冲的读写同步过程（初态（各缓冲区的空、满等）自行给出）；
（2）模拟缓冲池中缓冲区在不同工作方式下，所导致的缓冲队列的变化情况。
其中，初态（空缓冲队列、输入队列、输出队列等）自行给出；选择一种缓冲区的工作方式，查看各缓冲队列的变化情况。
2、 设计一个小型文件系统，提供创建、打开、读、写、关闭、删除文件的功能。
其中：（1）. 文件的内容象征性给出；
（2）. 基本文件目录、符号文件目录 ，活动文件表、活动名字表结构自行给出；
（3）. 提供存储管理功能（内存、外存）；
（4）. 提供文件保密措施 。
要求：（1）. 有方便使用的用户界面；
（2）. 要求每执行一次命令（创建、打开、读、写、关闭、删除）后，检查：
基本文件目录、符号文件目录、活动文件表、活动名字表、存储管理情况。
