I have some trouble understanding the linking process and hence this related question.
Lets say I need a global variable that is needed by every single source file in my project.
I would create a
constants.h header and put
extern const int var; in it. In corresponding source,
constants.cpp, I would put
const int var = 5; .(oh and a question here, wouldn't just
int var = 5; work?)
Then, every source file would get
Will source files, that don't
#include "constants.h" get access to
If so, how would it possible if there is no link between the 2 files?
