匈牙利命名规则

 匈牙利命名法规则大全

一般情况下，变量的取名方式为：

<scope_> + <prefix_> + <qualifier>。

　　范围前缀_，类型前缀_，限定词。

特殊的类型命名,前缀表示：

　　类、接口

前缀	类型	例子	备注
Lm	Class	LmObject	表示类型本身 不与范围前缀结合使用
I	Interface 接口	IUnknown

　　注：类名前缀改为Lm，对于非全局的类最好有语义表示其所属模块。类的实例命名与类名大致相同，只是类名语义表示类的通用含义，而类名表示此实例的具体语义。如类名LmSketPoint表示草图点的类定义，而它的两个实例 _StartPoint,_EndPoint分别代表起点和终点的语义。类的实例命名带上前缀_。

　　特殊约定：
　　a． MouseTool的派生类的前缀为_Mt.
　　b． 对话框类的前缀为CDlg.
　　c． 橡皮条类的前缀为_Rb.

范围前缀:

前缀	类型	例子	备注
g_	全局作用域	g_Servers
m_	成员变量	m_pDoc ,
l_	局部作用域	l_strName	少用

　　注：编程时尽量少用全局变量，对于全局变量还应在类型前缀后加上如下关键字：

　　特征模块   ：    Fea
　　草图模块   ：    Sket
　　装配模块   ：    Asm
　　工程图模块：    Lay
　　曲面模块   ：    Surf
　　界面模块   ：    Ui
