If x is an int where x = 0, what will x be after the following loop terminates?


while (x < 100)
x *= 2;


a) 2

a) 64

b) 100

c) 128

d) None of the above, this is an infinite loop

Answer: e. Explanation: Since x starts at 0, x *= 2; results in 0 * 2, or x = 0. Since x remains 0, (x < 100) remains true, and the loop repeats. x continues to be 0 and so the condition never changes to false, and thus the loop never terminates.
