I wanna create a global object in cpp program, how do I do that? Is this right? in "global_obj.h"
#include "class.h"
Class obj;
in "main.cpp"
extern Class obj;
We declare our globals as extern
in a header file, in your case: global_obj.h, and the actual global variable in a source file: global_obj.cpp. In separate source files we #include "global_obj.h"
to have access to them.
It should look like this:
global_obj.cpp
Class obj;
global_obj.h
extern Class obj;
main.cpp
#include "global_obj.h"
