Using perl etc is pretty clear but I don't know how to use C,C++ in the Action tag in the form attribute in HTML. Basically how does one go about using any compiled language to make a guestbook sort of thing? Also I can't find a tutorial on the subject! Plz help.

There's no difference. They're both programs. The output of a C program (in compiled form, of course) is sent to the client, just as the output of a Perl program is.

Thanks Taubz,

Actually I meant all the executables are OS dependent, so it seems a little confusing as the same compiled file will behave differently for diff servers unlike interpreted ones. Lets say the c compiled file is guest.exe, so is it enough to write action="guest.exe" at the tag? Also what about the cgi extension, as, if added afterwards, it will become guest.exe.cgi!! Plz give the exact format if the above one is not OK. Is there some example available that uses c/c++ for guestbook etc?

PS: By mistake I posted another copy of this as a new question outside and was not clear how to delete it. Don't bother about it.

Yes, they're OS dependent, so write the program for the platform on which you plan to use it. You don't need any additional extensions if your web server is set up to know where to find CGI programs. It all depends on your configuration.

Now its pretty clear. Thanx 4 ur support.

If you are using C++ you might want to use GNU CGIC. It makes it somewhat easier to write CGI stuff in C++. You can grab it at http://www.gnu.org/software/cgicc/cgicc.html . It is a completely portable library (about the only thing it uses is iostream), so it even works on Windows.

Thanks unknown. I'll check it out.
