# Bitwise Operators in C Programming: AND, XOR, OR, Complement and Shift Operations - Codzify Tutorials

There are many Bitwise operators in C as defined below:

**& (bitwise AND) :-** Takes two numbers as operand and does AND on every bit of two numbers. The result of AND is 1 only if both bits are 1.

**| (bitwise OR) :-** Takes two numbers as operand and does OR on every bit of two numbers. The result of OR is 1 any of the two bits is 1.

**^ (bitwise XOR) :- **Takes two numbers as operand and does XOR on every bit of two numbers. The result of XOR is 1 if the two bits are different.

**<< (left shift) :-** Takes two numbers, left shifts the bits of first operand, the second operand decides the number of places to shift.

**>> (right shift) :-** Takes two numbers, right shifts the bits of first operand, the second operand decides the number of places to shift.

**~ (bitwise NOT) :-** Takes one number and inverts all bits of it.

## Rule :-

& = 1 & 1 is 1 else 0.

| = any of two bit is 1 then 1 else 0.

^ = if both bits are different then 1 else 0.

a>> 1 = shift the bits of a to right by 1 and replace the first bit from left by 0 .

a>> 2 = shift the bits of a to right by 2 and replace the first two bits from left by 0 .

a<< 1 = shift the bits of a to left by 1 and replace the last bit from right by 0 .

a<< 2 = shift the bits of a to left by 2 and replace the last two bits from right by 0 .

~a = replace 0 by 1 and 1 by 0.

## Example :-

a= 5 = 00000101 b= 9 = 00001001 ————————————————————— a&b = 00000001 a|b = 00001101 a^b = 00001100 a>>1 = 00000100 a>>1 = 00001010 ~a = 11111010
