Can I execute a C/C++ program from HTML?

[the newbie]

Hi,

I know that this is not necessarily a FreeBSD related question, but it is
definitely programming related and this forum seems to me to be the best to
ask...

As indicated in the subject line, is it possible to call a C or C++ program
from HTML or any of the related internet languages?

I got pointed to this question today, when we spoke about network games and
I am still
looking for an answer.

Thanks!
