std::bitset::to_string

template <class charT = char,
          class traits = char_traits<charT>,

  basic_string<charT,traits,Alloc> to_string (charT zero = charT('0'),

Convert to string

Constructs a basic_string object that represents the bits in the bitset as a succession of zeros and/or ones.

The string returned by this function has the same representation as the output produced by inserting the bitset directly into an output stream with operator<<.

Notice that this function template uses the template parameters to define the return type. Therefore, these are not implicitly deduced.

Parameters

none

Parameters

zero, one: Character values to represent zero and one.

Return value

A string representing the bits in the bitset.

Example

// bitset::to_string
#include <iostream>       // std::cout
#include <string>         // std::string
#include <bitset>         // std::bitset

int main ()
{
  std::bitset<4> mybits;     // mybits: 0000
  mybits.set();              // mybits: 1111

  std::string mystring =
    mybits.to_string<char,std::string::traits_type,std::string::allocator_type>();

  std::cout << "mystring: " << mystring << '\n';

  return 0;
