Hungarian Notation (A flavour of...)

hungarian_notation.md

Hungarian notation is an identifier naming convention in computer programming, in which the name of a variable or function indicates its type or intended use. There are two types of Hungarian notation: Systems Hungarian notation and Apps Hungarian notation.

This flavour is simply prefixing the variable with 3 characters to quickly identify the data type of the variable. I find it's much easier to debug your code.
