operator‐=

Computes the set difference of this bitset and the b bitset.

operator<<=

Shifts the bits in this bitset to the left by n positions.

operator>>

Returns a shifted copy of *this.

operator>>=

Shifts the bits in this bitset to the right by n positions.

operator[]

Subscript operators

operatorˆ=

Bitwise‐XORs all the bits in this bitset with the bits in b.

operator|=

Bitwise‐ORs all the bits in this bitset with the bits in b.

operator~

Returns a copy of *this with all of its bits toggled.

pop_back

Decreases the size of the bitset by one, removing the most significant bit.

pop_front

Decreases the size of the bitset by one, removing the least significant bit.

push_back

Increases the size of the bitset by one, and sets the value of the new most significant bit to bit.

push_front

Increases the size of the bitset by one, and sets the value of the new least significant bit to bit.

rbegin

rbegin overloads

rend

rend overloads

reserve

Informs the bitset of a planned change in size, so that it can manage the storage allocation accordingly.

reset

reset overloads

resize

Changes the number of bits of the bitset to num_bits.

set

shrink_to_fit

Requests the bitset to reduce memory use by removing unused capacity.

size

Returns the number of bits in this bitset.

swap

Swaps the contents of this bitset and bitset b.

test

test_set

Sets bit pos if val is true, and clears it if val is false.

to_ulong

Returns the numeric value corresponding to the bits in *this.

operator<<

Returns a shifted copy of *this.
