area
定义一个基类MyGraph，要求有一个纯虚函数double Area()=0。从基类派生一个圆类Circle和矩形类Rectangle，再由Rectangle类派生出Square类，分别给出Area()实现。
重载“>>”，实现对图形信息的输入。在主函数中计算三种形状的面积，并显示输出。 (Define a base class MyGraph, requires a pure virtual function double Area () = 0. Derive a circle and a rectangle class Rectangle Circle class from the base class, and then by Square Rectangle class derived class, are given Area () implementation. Reload " > > " to achieve the input of graphical information. Calculate the shape of the three main functions in the area, and display output.)

多级反馈队列进程调度算法
1． 实验目的：
用高级语言编写和调试一个进程调度程序，以加深对进程的概念及进程调度算法的理解。
2． 实验内容：
编写一个模拟程序，完成单处理机系统中的进程调度,采用多级反馈队列的时间片轮转调度算法.
实验具体包括:首先确定进程控制块的内容,进程控制块的组成方式，确定相关参数(如进程数、到达时间、服务时间、时间片大小等) 然后完成进程创建原语、进程调度原语和进程撤销原语 最后编写主函数，上机实验并取得结果数据。
(The process of multi-level feedback queue scheduling algorithm 1. Experimental Objective: To use advanced language writing and debugging a process scheduler in order to deepen their understanding of the concept of the process and understanding the process of scheduling algorithm. 2. Experimental contents: the preparation of a simulated procedure, single-processor systems to complete the process of scheduling, the use of multi-level feedback queue scheduling algorithm Round-Robin Time Slice. Experiments include: First of all, the process control block to determine the content, process control block of the composition determine the relevant parameters (such as the process of the number of arrival time, service time, time slice size, etc.) and then complete the process of creating the original language, the process of scheduling the original language and the process of revocation of the original language the final preparation of the main function of the machine and obtain the results of)
