Question 1

What is the result of A XOR A?

Answer 1

A XOR A = 0. XOR-ing a value with itself always results in 0.

Question 2

What is the result of A XOR 0?

Answer 2

A XOR 0 = A. XOR-ing a value with 0 leaves it unchanged.

Question 3

What is the result of A XOR 1?

Answer 3

A XOR 1 = ~A. XOR-ing a value with 1 toggles its value (flips the bits).

Question 4

Is XOR commutative and associative?

Answer 4

Yes, A XOR B = B XOR A, meaning XOR is both commutative and associative.
