Write C++ Program to demonstrate the working of Bitwise Operators

Explanation:

The following table lists the Bitwise operators supported by C. Assume variable 'A' holds 60 and variable 'B' holds 13, then
Operator Description Example
& Binary AND Operator copies a bit to the result if it exists in both operands. (A & B) = 12 i.e., 0000 1100
Binary OR Operator copies a bit if it exists in either operand. (A ∣ B) = 61 i.e., 0011 1101
^ Binary XOR Operator copies the bit if it is set in one operand but not both. (A ^ B) = 49 i.e., 0011 0001
~ Binary Ones Complement Operator is unary and has the effect of 'flipping' bits. (~A ) = 61 i.e., 1100 0011 in 2's complement form.
<< Binary Left Shift Operator. The left operands value is moved left by the number of bits specified by the right operand. A << 2 = 240 i.e., 1111 0000
>> Binary Right Shift Operator. The left operands value is moved right by the number of bits specified by the right operand.



Code:

#include <iostream>
using namespace std;
int main()
{
    unsigned int a = 60;    /* 60 = 0011 1100 */
    unsigned int b = 13;    /* 13 = 0000 1101 */
    int c = 0;

    c = a & b;       /* 12 = 0000 1100 */
    cout << "Line 1 - Value of c is = " << c;

    c = a | b;       /* 61 = 0011 1101 */
    cout << "Line 2 - Value of c is = " << c << endl;

    c = a ^ b;       /* 49 = 0011 0001 */
    cout << "Line 3 - Value of c is = " << c << endl;

    c = ~a;          /*-61 = 1100 0011 */
    cout << "Line 4 - Value of c is = " << c << endl;

    c = a << 2;     /* 240 = 1111 0000 */
    cout << "Line 5 - Value of c is = " << c << endl;

    c = a >> 2;     /* 15 = 0000 1111 */
    cout << "Line 6 - Value of c is = " << c << endl;
}


Output:
