std::bitset<N>::to_string: std::bitset<N>::to_string

NAME

std::bitset<N>::to_string - std::bitset<N>::to_string

Synopsis

template<
class CharT,
class Traits, (until C++11)
class Alloc
> std::basic_string<CharT,Traits,Allocator> to_string() const;
template<
class CharT = char,
class Traits = std::char_traits<CharT>, (since C++11)
class Allocator = std::allocator<CharT>
> std::basic_string<CharT,Traits,Allocator>
to_string(CharT zero = CharT('0'), CharT one = CharT('1')) const;

Converts the contents of the bitset to a string. Uses zero to represent bits with value of false and one to represent bits with value of true.
The resulting string contains N characters with the first character corresponds to the last (N-1th) bit and the last character corresponding to the first bit.

Parameters

zero - character to use to represent false
one - character to use to represent true

Return value

the converted string

Exceptions

May throw std::bad_alloc from the the std::string constructor.

Example

// Run this code

  #include <iostream>
  #include <bitset>
  int main()
  {
      std::bitset<8> b(42);
      std::cout << b.to_string() << '\n'
                << b.to_string('*') << '\n'
                << b.to_string('O', 'X') << '\n';
  }

Output:
