C++ Coding Style

This blog is to demonstrate the coding style that I use.

1) Variable Naming Rule

Usually a variable 's name consists of 3 parts, which are scope, prefix, and qualifier. 
The formulation is [Scope]_[Prefix][Qualifier].

Eg. m_nAge 
m means it's a member variable of a class or a structure. 
n means it's integer. 
Age demonstrates the usage of this variable.

1.1) Scope

Scope is the range in which a variable can be referenced. 

l	local variable
g	global variable
m	member variable of a class or a structure
i	input variable
s	static variable

1.2) Prefix

Prefix indicates the type of a variable.

Index	Type	Prefix
1	sbyte	sb
2	byte	byte
3	short	s
4	ushort	us
5	int	n
6	uint	un
7	long	l
8	ulong	ul
9	bool	b
10	char	c
11	float	f
12	double	d
13	decimal	dm
14	struct	stu
15	enum	enum
16	object	o

1.3) Qualifier

Qualifier demonstrates the usage of a variable.
