Sure, that's fine too.
I have no objection to either
printf("%s\n", some_string);
or
puts(some_string);
I don't think of the latter as a microoptimization of the former, just
a different way of expressing it.
But I do prefer
putchar('x');
to
printf("%c", 'x');
I'm not sure I can articulate the reason.

Yup.
