std::bitset::to_string

STD：：位集：：to[医]弦

template< class CharT, class Traits, class Alloc > std::basic_string to_string() const;​(until C++11)
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;​(since C++11)

将位集的内容转换为字符串。使用zero表示值为false和one表示值为true...

结果字符串包含N第一个字符对应于最后的%28N-1TH%29位和对应于第一位的最后一个字符。

参数

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

返回值

转换的字符串。

例

二次

#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';
}
