Question

I got this question in a programming test. Do you think this question is even correct? Look at the answer choices. (2^x means 2 raised to x)

Consider the following pseudocode.

x := 1;
i := 1;
while (x >= 1000)
begin
x := 2^x;
i := i + 1;
end;

What is the value of i at the end of the pseudocode?

a) 4
b) 5
c) 6
d) 7
e) 8

I am sure that the value of i will 1. I told the examiner of the discrepancy and he advised me the leave the question unanswered if I felt it was incorrect. What else could I have done?

Answer 1

1

X < 1000, so it doesn’t enter the while.

Or there is an error in the Question (and X should be <= 1000 and not >=1000)

If it’s <= 1000 it should be 5:

2 – 4 – 16 – 65K

2 – 3 – 4 – 5
