Performs binary AND, OR, XOR and NOT.
1) Sets the bits to the result of binary AND on corresponding pairs of bits of *this and other
2) Sets the bits to the result of binary OR on corresponding pairs of bits of *this and other
3) Sets the bits to the result of binary XOR on corresponding pairs of bits of *this and other
4) Returns a temporary copy of *this with all bits flipped (binary NOT).
Note that &=, |=, and ^= are only defined for bitsets of the same size N.
Parameters
| other | - | another bitset |
Return value
1-3) *this

Example
Run this code
#include <bitset> #include <cstddef> #include <iostream> #include <string> int main() { const std::string pattern_str{"1001"}; std::bitset<16> pattern{pattern_str}, dest; for (std::size_t i = dest.size() / pattern_str.size(); i != 0; --i) { dest <<= pattern_str.size(); dest |= pattern; std::cout << dest << " (i = " << i << ")\n"; } std::cout << ~dest << " (~dest)\n"; }
Output:
0000000000001001 (i = 4) 0000000010011001 (i = 3) 0000100110011001 (i = 2) 1001100110011001 (i = 1) 0110011001100110 (~dest)
