Question

Which two statements are equivalent?

  1. 3/2
  2. 3<2
  3. 3*4
  4. 3<<2


Options:
A .  1 and 2
B .  2 and 3
C .  3 and 4
D .  1 and 4
Answer: Option C

(1) is wrong. 3/2 = 1 (integer arithmetic).

(2) is wrong. 3 < 2 = false.

(3) is correct. 3 * 4 = 12.

(4) is correct. 3 <<2= 12. In binary 3 is 11, now shift the bits two places to the left and we get 1100 which is 12 in binary (3*2*2).
