(1) 本实验要求使用C语言编程模拟一个拥有若干个虚页的进程在给定的若干个实页中运行、并在缺页中断发生时分别使用FIFO和LRU算法进行页面置换的情形。
(2) 虚页的个数可以事先给定（例如10个），对这些虚页访问的页地址流（其长度可以事先给定，例如20次虚页访问）可以由程序随机产生，也可以事先保存在文件中。
(3) 要求程序运行时屏幕能显示出置换过程中的状态信息并输出访问结束时的页面命中率。
-(1) This experiment requires the use of C language programming simulation of a virtual page number of the process in a given number of pages is running, and when the page fault occurred in, respectively, the use of FIFO and LRU page replacement algorithm of the situation. (2) the number of virtual pages can be given in advance (for example, 10), access to these virtual page address of the page flow (the length can be given in advance, for example, access to 20 virtual pages) can be randomly generated by the procedure can also be pre-stored in the file. (3) the requirements to run when the screen shows the process of replacement of the state information and the output end of the visit of the page hit rate.
