Increment variable in ruby

Ruby on-Rails Problem Overview

In Java, something like i++ would increment i by 1.

How can I do in Ruby? Surely there has to be a better way than i = i + 1?

Solution 1 - Ruby on-Rails

From the documentation,

> Ruby has no pre/post increment/decrement operator. For instance, x++ or x-- will fail to parse

So, you can do

i += 1

which is equivalent of i = i + 1
