Sort of, but it's *really* not idiomatic. You'd have to declare the
arrays to be one longer than they actually are so that array[N] is a
valid index. And then you'd end up not using the true first element of
the array. Not to mention most library functions use 0-numbering, so
you'd have to work around that as well.

So, it can be done, but you're going against the grain of the language.

Cheers,
Chris
