std::bitset (3) - Linux Manuals

std::bitset: std::bitset

NAME

std::bitset - std::bitset

Synopsis

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
reference (class)

Member functions

              constructs the bitset
constructor (public member function)
              compares the contents
operator== (public member function)
operator!=

Element access

              accesses specific bit
operator[] (public member function)
              accesses specific bit
test (public member function)

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

(C++11)

              returns the number of bits set to true
count (public member function)

Capacity

              returns the size number of bits that the bitset can hold
size (public member function)

Modifiers

operator&= performs binary AND, OR, XOR and NOT
operator|= (public member function)
operator^=
operator~

operator<<= performs binary shift left and shift right
operator>>= (public member function)
operator<<
operator>>
              sets bits to true or given value
set (public member function)
              sets bits to false
reset (public member function)
              toggles the values of bits
flip (public member function)

Conversions

              returns a string representation of the data
to_string (public member function)
              returns an unsigned long integer representation of the data
to_ulong (public member function)

to_ullong returns an unsigned long long integer representation of the data
              (public member function)
(C++11)

Non-member functions

operator& performs binary logic operations on bitsets
operator| (function template)
operator^
           performs stream input and output of bitsets
operator<< (function template)
operator>>

Helper classes

std::hash<std::bitset> hash support for std::bitset
                       (class template specialization)
(C++11)

Notes

If the size of the bitset is not known at compile time, std::vector<bool> or boost::dynamic_bitset may be used.
