std::bitset<N>::to_string

template<
    class CharT,
    class Traits,
    class Alloc 
> std::basic_string<CharT,Traits,Allocator> to_string() const;

template<
    class CharT = char,
    class Traits = std::char_traits<CharT>,
    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

Return value

the converted string.

Exceptions

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

Example

#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';
}
