Using: bitset( string() )

Hi there,

  I must be doing something wrong, but I do not understand the
documentation for bitset( string ), shouldn't this be equivalent (ref
== mask ) ?


#include <bitset>
#include <iostream>
#include <string>

int main()
{
  std::bitset<8> ref( 13ul );
  std::cout << ref << std::endl;

  const char v[] = "1101";
  std::bitset<8> mask( std::string(v) );
  std::cout << mask << std::endl;
  return 0;
}


Thanks
