On Windows environment when using Intel C++ compiler with Visual Studio 2010* or 2012*, the C++11 features supported by Visual C++ 2010/2012 are enabled by default. Use "/Qstd=c++11" to turn on the support for all other cases.
On Linux or Mac OS X environment use "-std=c++11".
Note: /Qstd=c++0x (-std=c++0x on Linux or Mac OS X) is still supported. it is the same as /Qstd=c++11(-std=c++11 on Linux or Mac OS X).
Please read the documentation for detail information under /Qstd (-std on Linux* or Mac OS* X) option.
See C99 Support in Intel C++ Compilerarticle for supported C99 features.
