THE SYNTAX OF A PROGRAMMING LANGUAGE tells you what code it is possible to write—what the machine will understand. Style tells you what you ought to write— what the humans reading the code will understand. Code written with a consistent, simple style will be maintainable, robust, and contain fewer bugs. Code written with no regard to style will contain more bugs. It may simply be thrown away and rewritten rather than maintained.

E:\Visual_C__MFC扩展编程实例 例18 动态地抓取应用程序的屏幕图像并将其打印。 上一个实例打印的是文档的报表，而不是当前出现在屏幕上的内容。在本例中，将实现 屏幕抓取并打印其内容。M F C 为打印视提供了有限的支持， 但只要用M F C 在 C Vi e w : : O n D r a w ( )中所提供的设备环境，就可以绘制自己的视。在打印视的时候， M F C只需调 用具备打印机设备环境的O n D r a w ( )函数即可。但是，如果不绘制自己的视，例如，用一个或 者一个以上的控件窗口填充自己的视就不会打印任何东西。每个控件将使用自己的设备环境 将自己打印到屏幕，因此打印视的唯一途径就是抓取屏幕(拷贝其内容到一个位图对象)并将其 打印到打印机。由于该功能整个与位图相关，因此将该功能封装到了位图类中。

acm HDOJ 1051WoodenSticks Description: There is a pile of n wooden sticks. The length and weight of each stick are known in advance. The sticks are to be processed by a woodworking machine in one by one fashion. It needs some time, called setup time, for the machine to prepare processing a stick. The setup times are associated with cleaning operations and changing tools and shapes in the machine. The setup times of the woodworking machine are given as follows: (a) The setup time for the first wooden stick is 1 minute. (b) Right after processing a stick of length l and weight w , the machine will need no setup time for a stick of length l and weight w if l<=l and w<=w . Otherwise, it will need 1 minute for setup.
