std::bitset
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.
Template parameters
N | - | the number of bits to allocate storage for |
Member types
proxy class representing a reference to a bit (class) |
Member functions
constructs the bitset (public member function) | |
compares the contents (public member function) | |
Element access | |
accesses specific bit (public member function) | |
accesses specific bit (public member function) | |
(C++11) |
checks if all, any or none of the 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) |
Non-member functions
performs binary logic operations on bitsets (function template) | |
performs stream input and output of bitsets (function template) |
Helper classes
(C++11) |
hash support for std::bitset (class template specialization) |
Notes
If the size of the bitset is not known at compile time, std::vector<bool> or boost::dynamic_bitset may be used.
