Style point:  such unadorned empty statements are worth avoiding.
They're not quickly apparent when scanning code ... either their
presence or their absence.  That translates to being bug-prone.

Same thing with all-in-one-line ... it's bad for if/else/while
as well as "for".

My preferred solution:

        for (...)
                continue;

Some folk like comments instead:

        for (...)
                /* nothing */;
