C++14: Binary literals

C++14 added ‘0b’ and ‘0B’ to be a literal prefix that specifies the literal represents a binary number. Here is an example:

#include <iostream>

int main()
{
  int i = 0b0;
  std::cout << 0b0 << " ";
  std::cout << 0B0 << " ";
  std::cout << 0b1010 << " ";
  std::cout << 0b00001010 << " ";
  std::cout << std::hex << 0b00001010 << " ";
  std::cout << std::hex << 0b1111101011111010 << " ";
  std::cout << std::hex << 0b11111010111110101111101011111010 << " ";
  std::cout << std::hex <<
   0b1111101011111010111110101111101011111010111110101111101011111010
    << " ";

  std::cout << std::endl;
}
/// Output: 0 0 10 10 a fafa fafafafa fafafafafafafafa
