⚡ Bitwise Operators

Last Updated: 16th August 2025

Bitwise operators work at the binary level (0s and 1s).
They directly operate on the bits of integers.

Hinglish Tip 🗣: Ye operators number ke bits par kaam karte hain (0-1 ke form me).

Operator	Name	Meaning	Example	Result
&	AND	1 if both bits are 1	6 & 3	2
|	OR	1 if at least one bit is 1	6 | 3	7
^	XOR	1 if bits are different	6 ^ 3	5
~	NOT	Inverts all bits	~6	-7
<<	Left Shift	Shift bits to left, fills 0 on right	6 << 1	12
>>	Right Shift	Shift bits to right	6 >> 1	3

✏ Syntax & Examples

a = 6   # binary: 110
b = 3   # binary: 011

print(a & b)   # 2  -> 010
print(a | b)   # 7  -> 111
print(a ^ b)   # 5  -> 101
print(~a)      # -7 -> two's complement
print(a << 1)  # 12 -> 1100
print(a >> 1)  # 3  -> 11

💡 Quick Practice

• Calculate 12 & 5 (hint: 12 = 1100, 5 = 0101).
• Try 7 | 4 and predict output.
• Check 9 ^ 5 → kya hoga?
• What will ~10 return?
• Use << to multiply 3 by 8 using shifting.
• Use >> to divide 40 by 4 using shifting.
