Yes. I believe that is required by the C standard.

But same C standard has a little quirk.

void f()

does not mean "no parameters" - it means "any number of parameters",
which effectively disable the parameter check.

For the not C savvy then to get "no parameters" one has to use:

void f(void)

Note that I did not have this on my "problem list" as I really don't
think it is a common cause of problems. The only interesting point
is that C++ fixed it.
