A little C++ question here. Hopefully, there are a few programmers still out
there
using it. :)

I'm getting the following warning when I compile this program. Can anyone
explain
why? More importantly, how can I eliminate the warning (besides disabling it
on the
compile command line)?

Thanks in advance for any assistance.

struct t {
        int turn;
};

void clearit( t b ) {
        b.turn = 0;
}

int main() {
        t game;
        clear( game );
        return EXIT_SUCCESS;
}
