Declaring Global Variables

Hi,

I'm programming with Visual Studio Express Edition 2005 and my source code consists of many separate header files (.h) and .cpp that describe the various classes. I would like, then, to declare a global variable that would work on all of those classes and also on my main.
Does anybody know how to do that?

Thanks

I suggest you avoid global variables and pass them through references between functions instead.
But if you really must use a global variable, then define it is a .cpp file, then put an extern inside a header file and include that header where you want to use the global variable:

Code:

---

int a;
extern int a;

---

Thanks, Elysia.
