1、 随机产生一串字符：根据这串字符进行打字练习。根据随机产生的字符来设定练习的难度：A等级：只随机产生一串小写字符；B等级：随机产生一串小写或大写字符；
2、 在完成打字练习过程中、对打正确的字符 则正常显示。
对打错误的字符 则以“*”显示。
3、字练习之后，需统计打对的字符数和打错的字符数进行统计。
点评:
1、一楼的功能基本实现了,不过,要把void main()改为int main(),不然编绎通不过.
2、二楼的似乎不合楼主要求.因为在输入错误时,不能及时回显*号,不过加上了时间统计,功强了功能.
楼主肯拿分砸，咱也不能让楼主失望。下面是我的程序，虽然是C++写的，不过全是面向过程的程序，改成C语言的起来很简单，如果楼主实在不想改了，可以写纸条给我。
