Declared in <bslstl_bitset.h>

Create a bitset with all bits initialized to 0.

constexpr
bitset() noexcept;

Create a bitset with its first M bit positions correspond to bit values in the specified val. M is the smaller of the parameterized N and 8 * sizeof(unsigned long long). If M < N, the remaining bit positions are initialized to 0.

constexpr
bitset(unsigned long long val) noexcept;

Create a bitset with its first M bit positions corresponding to the characters in the specified pos of the specified str. M is the smaller of the parameterized N and str.length(). If M < N, the remaining bit positions are initialized to 0. Characters with the value zeroChar correspond to an unset bit and characters with the value oneChar correspond to a set bit. The behavior is undefined if the characters in the specified str is not the specified zeroChar and not the specified oneChar.

Create a bitset with its first M bit positions corresponding to the characters in the specified pos of the specified str. M is the smaller of the parameterized N and str.length(). If M < N, the remaining bit positions are initialized to 0. Characters with the value zeroChar correspond to an unset bit and characters with the value oneChar correspond to a set bit. The behavior is undefined if any characters in str is neither the specified zeroChar nor the specified oneChar.
