***************************************************************************************** void DBG() { cerr << "]" << endl; } template<class H, class... T> void DBG(H h, T... t) { cerr << to_string(h); if (sizeof...(t)) cerr << ", "; DBG(t...); }

ifdef _DEBUG

define dbg(...) cerr << "LINE(" << LINE << ") -> [" << #__VA_ARGS__ << "]: [", DBG(__VA_ARGS__)

else

define dbg(...) 0

endif

Теги #debug, _debug, #c++ template, c++ 14, c++17
