template<class Char, class Traits, class Alloc> explicit bitset(const basic_string<Char,Traits,Alloc>& s, size_t pos = 0, size_t n = basic_string<Char,Traits,Alloc>::npos) | Conversion from string. Constructs a bitset, initializing the first M bits to the corresponding characters in s, where M is defined as min(N, min(s.size() – pos, n)). Note that the highest character position in s, not the lowest, corresponds to the least significant bit. That is, character position pos + M – 1 – i corresponds to bit i. So, for example, bitset(string('1101')) is the same as bitset(13ul). This function throws out_of_range if pos > s.size(), and invalid_argument if any of the characters used to initialize the bits are anything other than 0 or 1. |
bitset& operator&=(const bitset&) | Bitwise and. |
bitset& operator|=(const bitset&) | Bitwise inclusive or. |
bitset& operator^=(const bitset&) | Bitwise exclusive or. |
bitset& operator<<=(size_t n) | Left shift, where bit 0 is considered the least significant bit. Bit i takes on the previous value of bit i – n, or zero if no such bit exists. |
bitset& operator>>=(size_t n) | Right shift, where bit 0 is considered the least significant bit. Bit i takes on the previous value of bit i + n, or zero if no such bit exists. |
bitset operator<<(size_t n) const | Returns a copy of *this shifted left by n bits. Note that the expression b << n is equivalent to constructing a temporary copy of b and then using operator<<=. |
bitset operator>>(size_t n) const | Returns a copy of *this shifted right by n bits. Note that the expression b >> n is equivalent to constructing a temporary copy of b and then using operator>>=. |
bitset& set() | Sets every bit. |
bitset& flip() | Flips the value of every bit. |
bitset operator~() const | Returns a copy of *this with all of its bits flipped. |
bitset& reset() | Clears every bit. |
bitset& set(size_t n, int val = 1) | Sets bit n if val is nonzero, and clears bit n if val is zero. Throws out_of_range if n >= N. |
bitset& reset(size_t n) | Clears bit n. Throws out_of_range if n >= N. |
bitset flip(size_t n) | Flips bit n. Throws out_of_range if n >= N. |
size_t size() const | Returns N. |
size_t count() const | Returns the number of bits that are set. |
bool any() const | Returns true if any bits are set. |
