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';
}
