Can I use a binary literal in C or C++?
If you are using GCC then you can use a GCC extension (which is included in the C++14 standard) for this:
int x = 0b00010000;
You can use binary literals. They are standardized in C++14. For example,
int x = 0b11000;Support in GCC
Support in GCC began in GCC 4.3 (see https://gcc.gnu.org/gcc-4.3/changes.html) as extensions to the C language family (see https://gcc.gnu.org/onlinedocs/gcc/C-Extensions.html#C-Extensions), but since GCC 4.9 it is now recognized as either a C++14 feature or an extension (see Difference between GCC binary literals and C++14 ones?)
Support in Visual Studio
Support in Visual Studio started in Visual Studio 2015 Preview (see https://www.visualstudio.com/news/vs2015-preview-vs#C++).
