std::bitset
From cppreference.com
Defined in header
<bitset>

template< std::size_t N >
class bitset; |
||
The class template bitset
represents a fixed-size sequence of N
bits. Bitsets can be manipulated by standard logic operators and converted to and from strings and integers.
bitset
meets the requirements of CopyConstructible
and CopyAssignable
.

[edit] Member functions
constructs the bitset (public member function) |

checks if all, any or none bits are set to true (public member function) |
returns the number of bits set to true (public member function) |

Capacity |
|
returns the size number of bits that the bitset can hold (public member function) |
|
Modifiers |
|
performs binary AND, OR, XOR and NOT (public member function) |
|
performs binary shift left and shift right (public member function) |
|
sets bits to true or given value (public member function) |
|
sets bits to false (public member function) |
|
toggles the values of bits (public member function) |
|
Conversions |
|
returns a string representation of the data (public member function) |
|
returns an unsigned long integer representation of the data (public member function) |

(C++11)
|
returns an unsigned long long integer representation of the data (public member function) |
[edit] Non-member functions
performs binary logic operations on bitsets (function template) |
|
performs stream input and output of bitsets (function template) |
[edit] Helper classes
(C++11)
|
hash support for std::bitset (class template specialization) |
[edit] Notes
If the size of the bitset is not known at compile time, std::vector<bool> or boost::dynamic_bitset may be used.
