Visual studio c++ why don't 0b00000001 compile

Question

I am trying to port a small program I initially made for Linux, The only thing that gives me a error now is any binary numbers written like this 0b01010101.

I can't find any information on why this does not work on windows or how I could get it to work on windows.

Is this not standard in c++?

It's part of C++14 and MSVC hasn't implemented that part yet. FWIW, Clang works on Windows and Linux and does have this feature implemented with `-std=c++1y`. — chris, Mar 17 '14 at 17:06
See http://stackoverflow.com/questions/699781/c-binary-constant-literal for a way to use small binary constants in older compilers. — Mark Ransom, Mar 17 '14 at 17:08

Currently, this will not work.

This will be a new feature of C++14. Numeric literals in C++14 can be specified in binary form. The syntax uses the prefixes 0b or 0B.
