标准C中没有getch（）函数。如果你的
C实现恰好提供了一个，那就是一些实物
对C的扩展，而不是固有的。

Hi,
How do I read a char from stdin before the ''\n'' is pressed?
for example I know that I can use getch() to read a single char from the
user input, but suppose I wanted to read before the carriage return is
pressed.
for example I type a char and the following actions is done before the
''\n'' is pressed.
Thanks

Your questions *always* are FAQ slightly rewritten -- either you
are doing this to keep us busy or you are too lazy to read the thing.
Not fair. As promissed:

This is Question 19.1 in the comp.lang.c Frequently

<OT>Has anyone else noticed that on this newsgroup
the phrase "I know" almost always introduces a false
statement, or at the very least a gross misunderstanding?
I know I can''t be the only one who-- oh, drat!</OT>
There is no getch() function in Standard C. If your
C implementation happens to provide one, it''s some kind
of extension to C, tacked on rather than inherent.
for example I type a char and the following actions is done before the
''\n'' is pressed.
