Static variables:1. Static variables will be programmed into the EXE, from the start to the end of the program, it has been there;2. The initialization value of the static variable is 0;3. Global variables are static variables by default;4. A static

C + + programs are types and functions that are programmed to design types and functions and then organize them into C + + program structures. Because of the similarity of things, the types and functions of design sometimes exhibit the same nature.

Learning C + + language is a skill, and in any language, there are rules. For computer language, I think it should be understood first, then the superior to achieve it.C + + Language course is a highly practical course, it is necessary to write more

From: Huang Bongyong Handsome1. Note that member variables cannot be declared as virtual, meaning that virtual -View characters cannot be used in front of member variables.2. You should generally use a base-class pointer to call a virtual function,
