Bitwise Operators VS Logical Operators

Logical AND is represented by &&

Bitwise AND is represented by &

The logical AND operator works on Boolean expressions, and returns Boolean values only.

The bitwise AND operator works on integer, short int, long, unsigned int type data, and also returns that type of data.

Example:

#include<iostream>
using namespace std;
int main() {
   int x = 3; //...0011
   int y = 7; //...0111
   if (y > 1 && y > x)
      cout << "y is greater than 1 AND x" << endl;
   int z = x & y; // 0011
   cout << "z = "<< z;
}

Output:

y is greater than 1 AND x
z = 3

The && operator does not evaluate second operand if first operand becomes false. Similarly, || operator does not evaluate second operand when first one becomes true, but bitwise operators like & and | always evaluate their operands.

Example:

#include<iostream>
using namespace std;
int main() {
   int x = 0;
   cout << (x && printf("Test using && ")) << endl;
   cout << (x & printf("Test using & "));
}

Output:

0
Test using & 0
