It's not necessary to include the length in the declaration. For example
you could have
extern balance bal[];
in a .h file and
balance bal[YEARS];
in the corresponding .c file.
But *if* it makes sense to declare an array object in a header, then
it's not necessarily a bad idea to include the bounds in the
declaration. It lets you use `sizeof bal / sizeof bal[0]` to compute
the number of elements, for example.
On the other hand, it's likely better not to make the array object's
name globally visible in the first place.
