in this answer have seen c++11 code, don't understand (but to). there, variadic template function defined, (maybe?) takes arguments passed , inserts them std::ostringstream . this function (see complete working example @ linked answer): template<typename t, typename... ts> std::string createstring(t const& t, ts const&... ts) { using expand = char[]; std::ostringstream oss; oss << std::boolalpha << t; (void)expand{'\0', (oss << ts, '\0')...}; return oss.str(); } when had guess, i'd say, character array created , initialized \0 -bytes, , insertion of function's arguments stream happens side effect of initialization (part of comma expression). in end, array contains many nulls items inserted stream. it's casted void in order avoid compiler warning (unused variable). similar this: char arr[] = {'\0', (oss << t1, '\0'), (oss << t2, '\0'), ..., (oss <...
