Question

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

Answer 1

`i=2<4` is true, so "Hello" is printed, then we increment
`i` by 1.

Now
`i=3` and
`3<4`, so "Hello" gets printed again.

Next
`i=4`, but
`4<4` is false, so the while loop is broken.

So, the loop only prints "Hello" twice.
