There is a trick for this: #include <algorithm> (std::min)(17, 29) https://social.msdn.microsoft.com/Forums/vstudio/en-US/9b83c008-7bfc-483d-9395-959d4ccefff6/vs-10-where-is-cppmax-and-cppmin-or-equivalent?forum=vcgeneral (It works with MSVC, never used with gcc) |

Otherwise, if you really don't want to change the source code: using std::min; using std::max; |
