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.
4)
std::bitset<N>(*this).flip().
Example
#include <iostream>
#include <string>
#include <bitset>
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)
