    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()?

    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
    Microsoft says they are.

    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.

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