About The Variable Naming Tutorial
There are a lot of programmers that don't properly indicate what type of variable they are using. The best way to make your code understandable for
others and yourself is to properly preceed your variables and objects with an easy to understand prefix.
As a general rule (not always applied) it is best to prefix variables with a single letter, and prefix objects with three letters. Just follow the chart below.
This list is not an official prefix list. It's only a suggestion list using naming conventions I was taught, as well as a few official Microsoft naming conventions.
