What's rare about array objects?

An "object" is, by definition, a "region of data storage in the
execution environment, the contents of which can represent values"
(C99 3.14).  It can be of any type other than an incomplete or
function type: scalar (including arithmetic and pointer ("atomic"
means something else)), struct, union, or array.

Yes.  An array of integers is also an object itself.  Given:

    int arr[5];

arr is an object of type int[5], and each of its 5 elements is an
object of type int.
