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) bitset<N>(*this).flip()
Exceptions
(none) | (until C++11) |
noexcept specification: noexcept |
(since C++11) |
Example
Run this code
#include <iostream> #include <string> #include <bitset> int main() { std::bitset<16> dest; std::string pattern_str = "1001"; std::bitset<16> pattern(pattern_str); for (size_t i = 0, ie = dest.size()/pattern_str.size(); i != ie; ++i) { dest <<= pattern_str.size(); dest |= pattern; } std::cout << dest << '\n'; }
Output:
1001100110011001
