std::bitset::to_string - cppreference.com (original) (raw)

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.

[edit] Parameters

[edit] Return value

1. The converted string.

2. to_string<CharT, Traits, std::allocator<CharT>>(zero, one).

[edit] Exceptions

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

[edit] Notes

Since C++11, functions templates can have default template arguments. LWG issue 1113 removed the helper overloads (2-4) and added the corresponding default template arguments in (1).

[edit] Example

#include #include   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 *111 OOXOXOXO
