Bitwise Operator

C Language have the different types of bitwise operators, which can be apply on the integer types, long, int, short, char, and byte.
Bitwise operator works on to perform bit-by-bit operation. Assume if x = 60, and y = 13, now in binary format as follows:
x = 0011 1100
 y= 0000 1101
Different Result is :
x&y = 0000 1100
x|y = 0011 1101
x^y = 0011 0001
~x = 1100 0011

The following table of bitwise operators :
Assume integer variable X holds 60 and variable Y holds 13, then:

Operator Descriptions Example
& Binary AND Operator copies a bit to the result if it exists in operand. (X & Y) will give 12 which is 0000 1100
| Binary OR Operator copies a bit if it exists in either operand. (X | Y) will give 61 which is 0011 1101
^ Binary XOR Operator copies the bit if it is set in one operand but not both. (X ^ R) will give 49 which is 0011 0001
~ Binary Ones Complement Operator is unary and has the effect of 'flipping' bits. (~X ) will give -61 which is 1100 0011 in 2's complement form due to a signed binary number.
<< Binary Left Shift Operator. The left operands value is moved left by the number of bits specified by the right operand. X << 2 will give 240 which is 1111 0000
>> Binary Right Shift Operator. The left operands value is moved right by the number of bits specified by the right operand. X >> 2 will give 15 which is 0000 1111

Example :

Output :

Line 1 - Value of z : 12
Line 2 - Value of z : 61
Line 3 - Value of z : 49
Line 4 - Value of z : -61
Line 5 - Value of z : 240
Line 6 - Value of z : 15
