Performs binary AND, OR, XOR and NOT.
Sets the bits to the result of binary AND on corresponding pairs of bits of *this and other.
Sets the bits to the result of binary OR on corresponding pairs of bits of *this and other.
Sets the bits to the result of binary XOR on corresponding pairs of bits of *this and other.
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.

std::bitset<16> pattern{pattern_str}, dest;
for (std::size_t i = dest.size() / pattern_str.size(); i != 0; --i)

dest |= pattern;
std::cout << dest << " (i = " << i << ")\n";
