c++ - Defning a namespace class in a header file -

i have similar problem this not exact.

assuming have 2 header files , main.cpp. in first header file have :

  namespace logic   {     class gamemanager;   }

in second header:

#include "first_header.h" class logic::gamemanager  { public :      void init();     void run(): };

and in main.cpp have :

#include "first_header.h" int main() {    logic::gamemanager gm;    gm.init();    gm.run(); }

i error until include second header in main.cpp :

'gm' uses undefined class 'logic::gamemanager'

-is way of using namespaces , classes correct ?

-is there better way this?

thanks.

re-open namespace define class.

namespace logic {  class gamemanager  { public :      void init();     void run(): };  }

and include second header, not first, main.cpp. compiler cannot find class definition unless directly #include'd.
