I posted a followup a few minutes ago saying that you hadn't shown us
the declaration of array_int. I see that you had posted it, just not in
the same article. As you apparently now know, you defined array_int as
an int rather than as an int*, and that's the cause of the error
message.
The article I replied to didn't provide enough context to answer your
question about the error message. Knowing just how much quoted material
to retain when posting a followup can be tricky.
One more point:

array_int (assuming it's defined as int*) is not "a pointer to the
address" of the first element. It's a pointer to the first element.
A pointer doesn't point to an address. A pointer *is* an address.
More precisely, the terms "address" and "pointer value" are very
nearly synonymous. A (non-null) pointer points to an object; that
object has an address, and a pointer object may contain that address.
