DEBUG macros in C++

Question

I just encountered a DEBUG macro in C that I really like

#ifdef DEBUG_BUILD
#  define DEBUG(x) fprintf(stderr, x)
#else
#  define DEBUG(x) do {} while (0)
#e         


        

Answer 1

I use following micro,

#if DEBUG
#define LOGE2(x,y) std::cout << "ERRO : " << "[" << __FILE__ << "][" << __FUNCTION__ << "][Line " << __LINE__ << "] " << x <<":"<< y <

USE:

LOGE("ERROR.");
LOGE2("ERROR1","ERROR2");
