（1）从键盘输入当前系统的资源信息，包括当前可用资源，每个进程对各类资源的最大需求量，每个进程当前已分配的各个资源量和每个进程尚需要的各个资源量，并显示出结果在界面上。

（2）输入进程请求，按照设计好的安全性算法进行检查，得到结果并输出整个执行过程的相关信息和最终结果（主要包括资源分配表和安全序列）

（3）要求要有各种异常的处理，程序的可控制性和可连续性执行。包括对进程的存在有无检查，请求向量的不合法检查，试分配失败后的数据恢复和重新接受进程请求等。

-(1) Enter the current resource information system, including all resources currently available resources, the greatest demand for each process various resources, each process is currently assigned for each resource and each process is still needed from the keyboard, and displays the results on the interface.

   　(2) request to enter the process according to security algorithms designed to check, and outputs the results to obtain the final result of the whole information and execution process (including resource allocation table, and security sequence)

   　(3) required to have a variety of exception handling, process controllability and continuity of execution. Including the presence or absence of the inspection process, the request is not legitimate checks vector data recovery after a failed test and re-allocation process to accept the request and so on.
