在做论文，使用C语言文本屏幕界面设计，但是用的不好，希望大家能提供一些例程，谢谢

就是使用C语言的文本模式写界面设计,而不是图形模式.

是啊，我知道，我现在遇到的是我有三个参数是必须在一行，当输完第一个参数后，按回车，我定义的
if(key==7181) {clreol();scanf("%f",&Kp)}，后面的全被删除了，是因为用了clreol();,可我的目的只是想重新输入第一个参数，请大家告诉我好的方法。

真是想得出来，你这样做很费力并且效果不会很好．

那该怎么做，有好方法说一下

咦，你　的题目有疑义．"使用C语言文本屏幕界面设计",是在Ｃ语言文本模式下写屏幕界面？还是用Ｃ语言写文本屏幕界面？前一个解释比较麻烦，效果不大好．后一种解释明显是让你在图形模式下写屏幕界面．
