思勤无邪

上学时,因我年龄最小,个头也最小,上课时,就像大猩猩堆里的猴一般。如今,这猴偶尔也把最近的一些情况写在这里。

  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:

g_

m_

l_

  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

缺点多并不代表没有用,更何况这是一个成功的命名规则,至少Windows下的C/C++编程里随处可见。
这里也只是做一些总结,收集了一些常用的。  回复  更多评论
