Can you use the same namespace in 2 files? For ex:
test.h
namespace x
{
int i;
};
test2.h
namespace x
{
int u;
};
I guess you have you have to include test.h in test2 right? I just find this kinda peculiar because untill now I never really used namespaces a lot,and it's weird for me to see you can make definitions in the same namespace in different files.
Anyway,am I correct?
wait...so can i add variables and functions to the same namespace from different header files?
This is useful for forward declarations. For example, in you header file, you can do:
namespace XXX {
class YYY;
};
And then you can use declarations with references to XXX::YYY in your header file, without having to include the header file where the real declaration is.
