Why and when to use __noop?

Question

I was reading about __noop and the MSDN example is

#if DEBUG
   #define PRINT   printf_s
#else
   #define PRINT   __noop
#endif

int main() {
   PRINT(\"\\nhello         


        

Answer 1

How about:

if (condition)
  PRINT("hello\n");
next_statetment;

I think, that without __noop, in Release mode 'next_statetment' will be executed only when 'condition' is true, and this a bug, which is very difficult to find.
