I think the Roman numeral analogy is more than apt.
Tell me which man, speaking of his old collection of book, says: "The zero book i buyed was ..." The first book is of course the first. When he counts them, he says: "One, two, three..." If a guest asks: "How many books did you buy before this?" he answers: "Zero!" So, the guest understands, with a little calculation, what is the first book of collection. Zero is the OFFSET, the difference of the first book with itself, it is not a true number, is the result of a calculation. So, array[0] is something which make life easy to computer (element=base+offset), but it is an oddity for a not-computer-trained man. The zero element of a series does not exist. ciao (excuse my bad english) romano paolo tenca
