Is this a good way to embed debugging message in my program? (Macros)

Question

in the Debug.h file, I have the following:

#ifdef DEBUG_FLAG
    #define DEBUG(msg) std::cerr << #msg << std::endl
#else
    #define DEBUG(msg) for(;

You also need the while (0) for your debug macro. Will be very painful to debug if/else cases without it (if you are lucky, you will get a compiler error). See this question for more details.
