(until C++11)



(since C++11)

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.

Contents

Parameters

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

Return value

the converted string

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';
}

Output:

00101010
**1*1*1*
