bitwise operators

a = 5, b = 9
a&b = 1
a|b = 13
a^b = 12
~a = 250
b<<1 = 18
b>>1 = 4

Bitwise operators

#include <iostream>
using namespace std;

int main() {
    // Bitwise and & , bitwise or | , bitwise XOR ^
    // (10)10=(1010)2 ,(15)10=(1111)2
	int x = 10 & 15; // 1010
	int y = 10 | 15; // 1111
	int z = 10 ^ 15; // 0101
	cout << x <<endl;
	cout << y <<endl;
	cout << z <<endl;

bitwise operator

bitwise complement of N = ~N (represented in 2's complement form)
2'complement of ~N= -(~(~N)+1) = -(N+1)

bitwise operator

12 = 00001100 (In Binary)
