Description:
//程序说明：
// 一、开发语言：C#语言
//二、本程序模拟的是课本 银行家算法之例 编写的。
// 即系统中有五个进程{0，1，2，3，4}和三类资源{A,B,C},各进程的初始资源分配情况及各资源的总数量均
//参照该例子。
//三、本程序中共四个函数分别为：show(),apply(),test(),及主函数main()
// 其中：
// 1、show()的功能为：直观的列出系统某时刻的资源分配情况。
// 2、apply()的功能为：进程发出资源请求后，系统试探着把资源分配给该进程并修改数据结构中的数值。
// 3、test()的功能为：系统的安全性检测。
//四、需要注意的问题：
// 1、本程序的前提是假设当前只有一个进程请求资源。
// 2、一旦操作不符合要求会得到意想不到的结果!再按任意键可能该程序也不能正常运行,则就关闭该程序,
//然后再打开重新运行便可.
//五、课本上的例子在这个程序中运行后成功。
// 例如：P1：Request1(1,0,2)
// p4: Request4(3,3,0)
// P0：Request0(0,2,0)
// 再测试P0：Request0(0,1,0) 同课本上的结果相同。-//
// Program description:
//
// First, the development of language: C# language
// Second, the program simulates the textbook example of banker s algorithm, written.
// That system has five processes and three resources {0,1,2,3,4} {A, B, C}, each process of the initial distribution of resources and all resources of total volume
// Reference to the examples.
// Third, the program CCP four functions are: show (), apply (), test (), and the main function main ()
// among them:
// 1, show () function is: intuitive system resource allocation lists certain point in time.
// 2, apply () function as follows: After the process to issue a resource request, the system tentatively allocated resources to the process and modify the data structure values.
// 3, test () function as follows: security detection system.
// Four issues that need attention:
// 1, the premise of this program is the assumption that the current process only one request resource.
// 2, once the operation does
