Pseudo-code · Question 4 · Easy

What will be the output of the following pseudocode? (Note: &, | and ^ are bitwise AND, OR and XOR.)

Integer p, q
Set p = 6, q = 9
Print (p & q) + (p | q)
  1. 0
  2. 15
  3. 30
  4. 6
Answer and explanation

Answer: B. 15

Explanation: 6 is 0110 and 9 is 1001 in binary. They share no 1-bits, so 6 & 9 = 0 and 6 | 9 = 1111 = 15. The sum is 15.
