How to change array index to start from 1?

Question

How can I change my array's indices to start from 1 instead of 0. I am trying to fetch news from a site (JSON) and after parsing it:

@news = JSON.parse(Net::HTTP.get(URI.parse('http://api.site.com/news?format=json')))

But to see the individual news title, I have to do @news["items"][0] for the first link's title. Is it possible to change that behavior so when I do @news["items"][1] it shows me the first link's title?

Did I miss something, what's the problem with zero-based arrays? — Sergio Tulentsev

There's nothing wrong with it. It was for a voice application, so when user enters 1 it plays the title for the first link. Now, 0 is pressed for the first link — Timur

Every sane language I've tried uses zero-based array access. You better get used to it (or you can switch to VB) :) — Sergio Tulentsev

Well, you can intercept and interpret that user input, can't you? — Sergio Tulentsev

Bing! Yes, I subtracted 1 from user's input and now it works! Thank you man! — Timur

You should intercept user input and adjust entered value to map to a correct array element. In general, you should always validate user input and check if it makes sense.
