Question

How many times does the computer print the string "Hello"? i = 2
while (i < 4) {
print ("Hello")
i = i + 1}:

Answer 1

I think 3 times right?

Answer 2

We start with i = 2. Let's just insert the value of i in and check each time we run the while loop.
(2 < 4) -> print "Hello", add one
now, i =3
(3 < 4) -> print "Hello", add one
now, i = 4
(4 < 4) We stop!

We printed it twice before we stopped.

Answer 3

OK, I see.. Thanks
