VC++使用OPT页面置换算法的程序示例，OPT页面置换算法来实现当页表中发现所要访问的页面不在内存时调入内存，使内存的资源得以充分利用。本课题主要的目的是为了在虚拟页式存储管理中，当进程运行时，发生缺页中断时，使用一种很好的页面置换算法，使系统性能变得更好。

-VC++ using the OPT page replacement algorithm sample program, OPT page replacement algorithm to achieve when the page table to be found to visit the page of memory is not transferred to memory so that memory resources can be fully utilized. The main purpose of this task is to manage virtual memory page, when the process of run-time, page fault occurs, the use of a good page replacement algorithm, so that a better system performance.
