C++ binary constant/literal

Question

I\'m using a well known template to allow binary constants

template< unsigned long long N >
struct binary
{
  enum { value = (N % 10) + 2 * binary<          


        

Answer 1

Technically it is not C nor C++, it is a GCC specific extension, but GCC allows binary constants as seen here:

 The following statements are identical:

 i =       42;
 i =     0x2a;
 i =      052;
 i = 0b101010;

Hope that helps. Some Intel compilers and I am sure others, implement some of the GNU extensions. Maybe you are lucky.
