⑴设计一个模拟内存分配的系统；

⑵采用分页内存管理策略；

⑶输入数据为进程号，需要的内存量，并根据这些信息进行内存分配；

⑷输入数据为进程号，则将该进程占用的内存释放；

⑸动态显示分配结果，用位示图来表示内存的使用情况。

-⑴Designs a simulation memory allocation the system　⑵Uses the paging memory management strategy　⑶The data-in is the advancement number, needs the memory quantity, and carries on the memory allocation according to these information　⑷The data-in is the advancement number, memory release which takes this advancement　⑸The dynamic demonstration assignment result, shows the chart with the position to express the memory service condition.
