They probably would. I prefer the plain C version, though. Chess programs
are typically rather small and simple programs, written by a single person
rather than a big team. In other words, it they are precisely the kind
of programs where the advantages of OOP aren't really very important.
There are probably cases in a chess program where using classes would be
slightly more convenient or elegant, but I think the difference is not big
enough to matter much in practice. Sticking to ANSI C ensures that the
program is more easily portable to a wide range of platforms (C compilers
are still more widespread than C++ compilers, I think), which, at least
to me, is more important than the very minor advantages switching to C++
would buy me.
