The "static", if this is at block scope, specifies that the pointer
object, not the array object, has static storage duration.  If it's at
file scope it specifies that the name "s" is not visible to other
translation units.  Either way, use it if that's what you want, don't
use it if it isn't.

There's no good reason not to use "const".  (If string literal objects
were const, you'd have to use "const" here.)

If you also want the pointer to be const, you can write:

    const char *const s = "hello, world";
