定义点Point类作为基类，在此基础上派生出直线Line类和圆Circle类，在Circle类的基础上以不同的属性派生出圆柱Cylinder类和球Spheroid。并要求基类和各派生类具有以下特点： （1） Line类含有计算直线长度和斜率的成员函数。 （2） Circle类含有计算圆面积的成员函数。 （3） Cylinder类含有计算圆柱表面积和体积的成员函数。 （4） Spheroid类含有计算球体的表面积和体积的成员函数。 (Point definition of point type as the base category, on the basis of a straight line derived Circle Circle Line category and class, in the Circle class based on different attributes derived Cylinder class and ball cylinder Spheroid. And requested the base class, and factions of Health category has the following characteristics: (1) Line category contains the length and slope of a straight-line calculation of member functions. (2) Circle type of circular area containing the members of the calculation function. (3) Cylinder category contains cylindrical surface area and volume calculation of the member functions. (4) Spheroid Spheroid category contains the calculation of surface area and volume of the member functions.)

在UNIX下经常要看大日志，vi又打不开,pg又不能一行一行翻，more就更是乱码了。于是自己做了个程序来查看日志，包括跳转，查找等。 自动识别汉字、全角字符、日文，真正做到光标随字移动 窗口化全屏浏览 宽行浏览，完全显示文本原始信息 支持查找、跳转、打印，任意滚屏 支持任意大小的文本，特别适合分析系统大日志 动态内存分配，系统资源消耗少 方便UNIX用户使用，完全仿真vi指令 支持custom命令安装，软件管理方便 内置指令帮助 (Under UNIX often depends on large logs, vi and open, pg line by line can not turn, more even more garbled. So do yourself a program to view the log, including jumps, look like. Automatic character recognition, full-width characters, Japanese, truly moving the cursor over the word wide rows fullscreen browsing browsing, fully display the text of the original information to support search, jump, print, scrolling support any size of any text analysis system is particularly suitable for large Log dynamic memory allocation, consume less system resources UNIX user convenience, complete simulation of vi commands to support custom commands to install, easy management software built-in command help)
