宏全部使用大寫字母--------宏大寫

結構體名字全部使用typedef，typedef之后的名字為大寫-------結構體別名大寫

函數名全部使用小寫字母，單詞之間使用下劃線分割-------函數名小寫，單詞之間下劃線（1）

函數名第一個單詞全小寫，后面單詞的首字母大寫，單詞之間使用下劃線---------函數名首單詞小寫，后面單詞首字母大寫（2）

變量名也是全部使用小寫，單詞之間使用下劃線分割-------變量名小寫，單詞之間下劃線（1）

變量名第一個單詞全小寫，后面單詞的首字母大寫，單詞之間使用下劃線---------變量名單詞小寫，后面單詞首字母大寫（2）

變量的命名前后綴規則如下（這是匈牙利命名法的前后綴格式，以后其他地方使用上述的總結，前后綴使用匈牙利的）：

The type prefix indicates the data type of the variable.

Type prefixMeaningExample

b	boolean	bool bHasEffect;
c (or none*)	class	Creature cMonster;
ch	char (used as a char)	char chLetterGrade;
d	double, long double	double dPi;
e	enum	Color eColor;
f	float	float fPercent;
n	short, int, long char used as an integer	int nValue;
s	struct	Rectangle sRect;
str	C++ string	std::string strName;
sz	Null-terminated string	char szName[20];

The following type modifiers are placed before the prefix if they apply:

Type modifierMeaningExample

a	array on stack	int anValue[10];
p	pointer	int* pnValue;
pa	dynamic array	int* panValue = new int[10];
r	reference	int rnValue;
u	unsigned	unsigned int unValue;

The following scope modifiers are placed before the type modifier if they apply:

Scope modifierMeaningExample

g_	global variable	int g_nGlobalValue;
m_	member of class	int m_nMemberValue;
s_	static member of class	int s_nValue;

補充：

• p ---------for a pointer. A pfoo would be a pointer to data item of type FOO
• pp------- for a pointer to a pointer.
• h --------for a heap handle. This is a pointer to a pointer that points at a data item recorded within a heap.
• rg -------for an unstructured array containing data items of a certain data type. An rgfoo would be an array that contains data of type foo. Individual elements would be selected by an ifoo index variable.
• mp -------for an array which is used to map from one data type to another.Eg. A mpdochdod would be indexed via a doc index. The expression mpdochdod[doc] would produce a handle to a document descriptor.
• dn-------- for an array whose elements that describes a meaningful index such as an opcode. If the meaningful index were an OP type, a data structure of type EOP (entries for OP) would be defined, and a dnop array would be defined which describes what each individual op means

Max - added to an index data instance which records the actual size of an array or data block.
eg. the declaration of a an array of type FOO in C would be: FOO rgfoo[ifooMax];

Mac - added to an index data instance to indicate the limit of an actual usage within an array.Mac stands for current maximum. It is invariant that ifooMac <= ifooMax. ifooMac == ifooMax is the condition which is true when all entries within an array are in use.

First - added to an index or pointer which designates the first element within a range that may be validly processed

Last - added to an index or pointer which designates that last entry within a range that may be validly processed.

Lim - stands for limit. An ifooLim is equal to ifooLast + 1 and designates the location where a new foo item could be recorded in an array or data block.
