Answer 1

Do you know about how bitwise & works? The result is correct. What result you were expecting?

Bitwise operators check bits of both operands one by one. If both the bits are 1 , corresponding bit in result is set to 1 otherwise 0.

1 -> 01
2 -> 10

1&2 -> 00

Answer 2

Neba Emmanuel , && isn't bitwise operator. It's a logical operator.

&& - Logical.
& - Bitwise.
