Declaration

bitset<N>& bitset<N>::operator&=(const bitset<N>& kqrRightSide);

Description

This is the member function operator&=() for the bitset class template. This function performs a bitwise "and" on the bitsets and stores the result in the left-hand side bitset.

Header Include

#include <bitset>

Example

#include <bitset>
#include <iostream>

int main()
{
	using namespace std;

	// Create two bitsets
	bitset<4> qBits1(5);
	bitset<4> qBits2(3);
	cout << "bitset<4> #1: "<< qBits1 << endl;
	cout << "bitset<4> #2: "<< qBits2 << endl;

	// Take the bitwise and of the two bitsets
	cout << qBits1 << " & " << qBits2 << " = ";
	qBits1 &= qBits2;
	cout << qBits1 << endl;

	// Keep the window open
	cin.get();
	return 0;
}
