Zero, one, two, Freddy's coming for you

by Andrey Karpov

From the article:

This post continues the series of articles, which can well be called «horrors for developers». This time it will also touch upon a typical pattern of typos related to the usage of numbers 0, 1, 2. The language you're writing in doesn't really matter: it can be C, C++, C#, or Java. If you're using constants 0, 1, 2 or variables' names contain these numbers, most likely, Freddie will come to visit you at night. Go on, read and don't say we didn't warn you.
