Poor English notwithstanding, those highlighted words should be
"define", not "declare".  There is a BIG difference between declaring
something and defining it.  Here's a really general definition:

"declare" = announce that something exists
"define" = create that something

You can have as many declarations of a given object as you want, but one
and only one definition.
