I tought my VS 2015 use the new C++11 compiler version. Does I have missed somewhat? I tried different Platform Toolset: v90 ..v140. None helps.

Used code to check the C++ compiler version: How to get the C++ version

#include <iostream>

//  Print the current used C++ version
int main()
{
  int version = __cplusplus;
  if (__cplusplus == 201103L) std::wcout << "C++11\n";
  else if (__cplusplus == 199711L) std::wcout << "C++98\n";
  else std::wcout << "pre-standard C++\n";
}

The console output is: C++98 for all Plattform Toolset

That's because `__cplusplus` is probably `201402`. – Hatted Rooster Sep 08 '17 at 13:47

Test standard versions with `>=`, always. Otherwise your code stops "guessing" correctly when the *next* standard comes out. – DevSolar Sep 08 '17 at 13:48

Even Visual Studio 2017, when set to `ISO C++ Latest Draft Standard (/std:c++latest)` reports 199711. – Retired Ninja Sep 08 '17 at 13:50

Then how do I know if a C++11 feature is there? Do I have to use _MSC_VER instead? (Ex: _MSC_VER == 1900 for VS2015) – Tom Tom Sep 12 '17 at 08:07
