C Bit Manipulation Problem

[Garee]

When I perform the calculation 25441 & 0000000011111111 the answer I recieve is puzzling. Instead of the expected 97 I instead get 577.

printf( "%d", 25441 & MASK );

The output is 577 where MASK is 0000000011111111.

I performed the bitwise addition manually to double check and the answer should definitely be 97. I must have an error somewhere.

Any help is much appreciated.

It's because you are mixing number bases. You are using decimal and you are wanting MASK to be in binary.

Excellent - That makes perfect sense.

Thank you for your time.
