When I started out as a wee programmer back in the 1980s, “Hungarian Notation” was all the rage. Invented by Charles Simonyi (a Hungarian guy!), it espoused a naming convention for variables that included the intent (or kind, or type) for that variable. Unfortunately, the semantic meaning of type is overloaded, and many developers assumed it meant “data type.” So, you had variables that were clearly string variables called strFirstName or clearly integer variables called intCount. In a type-safe compiled language, this is redundant, but many Microsoft devs, myself included, blindly followed the pattern because we learned it, and it made sense on the surface.
