A Convention for Naming Variables

A Convention for Naming Variables

Naming variables has a major effect on how hard it will be for a person to follow the code, whether it is the same person who wrote it or someone else. To avoid confusing others, many programmers use the Hungarian Naming Convention when naming variables. This way, variables of same type have the same prefixes.

Prefix		Typef		booleanch		charsz		zero-terminated stringfn		functionw		wordb		bytel		longu		unsigned wordbit		a single bitv 		voidp		pointeri		index to an arrayh		handlemp		an array

And so on…

Here are some examples:

char szName[40], *pchSex;int uAge;int fIsMarried;int mpChildAges[4];etc.
