TRUE OR FALSE

1. ANDing an operand with 1 sets the zero flag if the operand was originally an even number.

2. The OR instruction can be used to find the intersection of two bit-mapped sets.

3. The JO instruction is used after an operation involving signed integers.

4. XORing an operand with 1 always causes the Zero flag to be set.

5. The XOR instruction can be used to generate the two's complement of an integer.

Answer #1

TRUE OR FALSE

1. ANDing an operand with 1 sets the zero flag if the operand was originally an even number. True. This is because, ANDing two operands will set the zero flag if both the operands are not the same. There is nothing to do with the number being even or odd. But, as the other operand is 1(i.e., odd). ANDing an even operand will obviously result in inequality and the zero flag is set.

2. The OR instruction can be used to find the intersection of two bit-mapped sets. False. The OR instruction can be used to find the UNION and not the INTERSECTION.

3. The JO instruction is used after an operation involving signed integers. True. JO stands for Jump on Overflow. When involved signed integers, and if the overflow flag is set, then the jump will happen.

4. XORing an operand with 1 always causes the Zero flag to be set. False. This is because, XORing two operands will set the Zero flag only when the two operands are the same.

5. The XOR instruction can be used to generate the two's complement of an integer.
