Hi
I note there are two functions putch() and _putch() in VC++ Library.
Which one should be used under specified situation. What is the difference
between putch() and _putch()?

Thanks!

Neither of these functions is part of the standard C++ library, or the
standard C library either, for that matter. So they do whatever
Microsoft says they do, and the differences between them are whatever

Since they are non-standard, we don't discuss them here, but if you
can't figure out the difference from the compiler's documentation
there are several places you can look for more information:

MSDN, on Microsoft's web site.

The Microsoft support groups in the family.

A newsgroup like

There is no difference, the one with the underscore in front is just the
decorated name.
