这是我做的操作系统里面的银行家算法的源程序，发上来供大家参考。(caozuoxitongyinhangjiasuanfa)

说明：  几个算法分析和操作系统的上机小程序，vc,c#实现(several algorithm analysis and operating systems on the plane small program vc, c#)

这个程序是模拟采用二级目录结构的磁盘文件系统中的文件操作，它可以实现对文件的一些基本管理，如：读、写、删除文件等。通过这个程序可掌握文件子系统的原理，加深对二级目录结构的文件系统中用户管理、文件管理、目录管理的理解，并用程序实现对文件子系统的模拟。(the procedure is simulated using two disk directory structure of the file system file manipulation, it can be achieved on some basic document management, such as : read, write, delete files. Through this procedure can grasp the principle document subsystems to enhance the structure of the two file system user management, document management, directory management, understanding, and the procedures to achieve the right documents subsystem simulation.)

模拟段式存储管理的分配与回收，能够输入给定的内存大小，进程的个数，每个进程的段数及段大小；当某进程提出申请空间的大小后，显示能否满足申请，以及为该进程分配资源后有关内存空间使用的情况。 (Analog-stage distribution of storage management and recovery, be able to enter a given memory size, number of processes, each process segment number and segment size when a space the size of the application process, the show can meet the application, as well as the The process, after the allocation of resources relating to the use of memory space.)

说明：  手机天气预报系统，可以更改城市名字和显示天气，手机symbian 下使用(Mobile weather forecasting system, you can change the city names and display the weather, the use of mobile phones symbian)

模拟操作系统进程调度的算法采用时间片轮转法和优先权法(operating system simulation process scheduling algorithm-time Web-law and law priority)

dos 工具 用老版本的gcc编译，否则会出错(dos tools with older versions of THING)

哲学家进餐的问题，用程序模拟实现，解释死锁的产生、解除以及预防(dining philosophers problem, simulation procedures, explained Deadlock in lifting and prevention)

加深进程概念的理解；掌握选择进程调度算法的准则；掌握进程调度算法。 (Deepen the process of understanding of the concept master scheduling criteria selection process algorithm master process scheduling algorithm.)

说明：  ucos2 vc++移植代码 通过VC++编译，每2S显示一次任务(ucos2 vc++ code migration)
