Since you're using C (Like myself) and just starting, probably the easiest
way to display output is simply to use a standard text-output routine. If
you're compiling a DOS or console application (with a main() style entry
point), printf() is likely the simplest. It takes a string for it's first
argument, followed by a variable-length list of arguments which are
inserted into the string in order wherever a %s (string), %d (int), %f
(float), ad etcetera is found. Use \n for a new line. You probably want to
look up a list of all the different symbols that the function uses on the
web. If you're making a Windows program (with a WinMain() style entry
point), a cheap way of displaying messages is to call MessageBox(NULL,
"Message", "Title", MB_OK). I understand that because of the calling
conventions of Windows functions, they can't use variable-length argumant
lists. To display values of variables, instead of "Message", you could use
an array of chars (a string variable) and wsprintf(stringvar, "The value of
foo is: %d", foo) before displaying the box.

I never noticed, but now that you mention it, I'll check . . . <checking> .
. . I think that you're right. Looks like it supports a couple of
languages, but not C++.
