But Global Variable is dangerous and vulnerable to be changed out of this effective region. Even if you defined a Static Global Variable only in this .obj. You have protected from changed by other .obj. However, it is still vulnerable to be changed in this very .obj by other functions. ...
static (Global) Function:有文件作用域,只在本文件中使用 Global Function:无文件作用域 static Member (in Function) variable:函数调用完成后,变量保存状态,再次调用函数,不会重新分配空间 Member(in Funcition) variable:函数内的生命周期 static Member(in Class) variable:属于类范围, Member(in Class) variable...
(1) a static local variable defines its lifetime in the function as the entire source, but its scope remains the same as that of the automatic variable, and can only be used within the function defining the variable. After exiting the function, you cannot use it even though it still ...
changes its lifetime. Changing a global variable to a static variable changes its scope and limits its use. So the role of static this descriptor is different in different places. 4. Static function ... internal and external functions
