Multiple Choice

Evaluate 0xC9 OR 0x2A.

Explanation:
Bitwise OR looks at each bit position and puts a 1 there if either input bit is 1. To see it clearly, convert the hex values to binary: 0xC9 is 11001001 and 0x2A is 00101010. OR them bit by bit: 11001001 OR 00101010 equals 11101011, which is 0xEB. In decimal, that’s 235. The other options don’t match this bit-by-bit result, so 0xEB is the correct outcome.
