Yes, we don't have a clear guidelines on this, but this would sure
matches into mixed declaration and expression. And some variables are
initialized and some aren't in the same line. I was confused in my
first glance.

Yes, both of them can't be negative. As I explained in the part you
removed. However, I choose ssize_t in my reply because it's
a ptrdiff_t.
So, size_t is an obviously a better choice.
Either size_t and ssize_t could be used in this case, but not int.
