C++ code style

There are many statements about C++ code style, and I would only mention what troubled me in the past.

1)

A default value must be initialized for variables in c++; otherwise, code works in debug mode while not in release mode for undefined value in the memory for those variables.

 

2)

For the classes used, Prefer foreward declare (前置申明) to include a header file  for it

//class Class Aclass   //struct  Extern Astruct;

 

3)

a acceptable way for naming variables in C++ as below:

 变量命名

   m_   成员变量

   l_      局部变量

   a_    输入参数变量

   C     类名首字母

   I     “接口”类(纯虚抽象类)名首字母
