bitset(
std::basic_string<CHAR_TYPE, TRAITS, ALLOCATOR> const& str,
std::basic_string<CHAR_TYPE, TRAITS, ALLOCATOR>::size_type pos = 0,
std::basic_string<CHAR_TYPE, TRAITS, ALLOCATOR>::size_type n = std::basic_string<CHAR_TYPE, TRAITS, ALLOCATOR>::npos,
CHAR_TYPE zeroChar = CHAR_TYPE('0'),
CHAR_TYPE oneChar = CHAR_TYPE('1'));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.
| Name | Description |
|---|---|
| str | character sequence providing bit values |
| pos | starting index in str (default 0) |
| n | maximum number of characters to use (default npos) |
| zeroChar | character representing an unset bit (default '0') |
| oneChar | character representing a set bit (default '1') |
