Where did GNU C++0x go? Why is it no more among the language options?
Incidentally, can to_string() work with other C++ variants? Or what else to use alternatively for converting from int to string? Solution with stringstream seems too slow to write...








GNU C++11 is almost the same. But there's a bug.
Maybe you should use C constructions,
sprintffor example, if you're worried about time limit.According to the wiki page C++0x is the former name of C++11. So I guess C++11 is the same .
