问题的提出:我们在编制程序时,经常要用到清屏处理,如dos下的cls,Turbo C下的clrscr()等都具有清屏功能,但这些均为一般意义的清屏,并未显示其清屏规律.而有时为了达到清屏的艺术美观,往往对清屏有一些具体要求,如:开幕清屏 闭幕清屏 上清屏 下清屏 中清屏.为此,这里用C语言编制了几个子函数,用于程序中时,既可达到清屏的目的,有能增加屏幕的艺术美观.-the problem : we in the preparation of procedures, regular use of the screen, such as the dos cls, Turbo C under the clrscr () so with the screen, but these are general sense of the screen does not show the screen law. And sometimes in order to achieve the screen beauty of art often on the screen that there are some specific requirements, such as : opening screen closing supernatant Ping-ping-ping under which the screen. To that end, here with C language several Functions for the procedure, can achieve the purpose of the screen, the screen will increase the artistic aesthetic.
