Capgemini | Pseudocode Questions | Question 1

What will be the output of the following pseudocode?

Initialize Integer x, y, z
Set y = 1, x = 2
z = x ^ y
Print z

(A)

1

(B)

2

(C)

4

(D)

3

Answer: (D)
Explanation:

Firstly variables x, y, and z are initialized, then y and x are assigned values 1 and 2 respectively.
Now z is assigned the value of x XOR y i.e. 1 ^ 2 = 3. Since all bits in 1 and 2 are exclusive so the XOR will be equal to 1 OR 2 i.e. 3
