Q3. Logics on bit wise operators
Ans. 
Bitwise operators are used to perform operations at the bit level on binary numbers.
• Bitwise AND (&) - sets a bit to 1 only if both input bits are 1

• Bitwise OR (|) - sets a bit to 1 if either input bit is 1

• Bitwise XOR (^) - sets a bit to 1 if the input bits are different

• Bitwise NOT (~) - inverts all the bits

• Left shift (<<) - shifts the bits to the left by a specified number of positions

• Right shift (>>) - shifts the bits
