The expression value & 1 masks all bits except for the least significant bit. True or False?

Explanation:
Isolating the least significant bit is what happens when you use a bitwise AND with 1. The binary value 1 has zeros in every bit position except the least significant one, so when you perform value & 1, every higher bit is ANDed with 0 and becomes 0, while the least significant bit is ANDed with 1 and remains unchanged. The result is either 0 or 1, effectively masking all other bits. So the statement is true. It’s not masking the MSB or two LSBs; those would require different patterns.
