How is this better than the sizeof method? This looks like a clever way to access sizeof information without explicitly using the sizeof operator.

It isn't better. I don't think it was claimed to be.

But if you really understand C, it should also not be a surprise that it works this way.

I think it is better in exactly zero ways.

It is, nonetheless, different.
