1. Title:
   25c s Different Behavior Based On Certain Condition- Smoothie Quiz
2. Description:

3. 530 0:01 - 0:02
   I love smoothies.
4. 1780 0:02 - 0:04
   Let's look some code from
   the SmoothieActivity.
5. 5100 0:05 - 0:09
   First, we create an integer variable
   called numberOfSmoothiesTillPrize and
6. 9169 0:09 - 0:11
   we initialize that to a value of ten.
7. 11060 0:11 - 0:14
   Then we have an if-else statement.
8. 13930 0:14 - 0:17
   It spans from line two to line seven.
9. 16940 0:17 - 0:21
   If the numberOfSmoothiesTillPrize
   is greater than nine,
10. 20710 0:21 - 0:24
    then do the code within the opening and
    closing braces here.
11. 23890 0:24 - 0:30
    If this statement is not true, then do
    the code in this else block right here.
12. 29690 0:30 - 0:34
    Since the numberOfSmoothiesTillPrize
    has a value of ten, and
13. 33805 0:34 - 0:38
    ten is greater than nine,
    then we fall into the if case here.
14. 38450 0:38 - 0:40
    We print out a log message that says,
15. 40260 0:40 - 0:43
    'Congratulations, you
    get a free smoothie!".
16. 42930 0:43 - 0:47
    Then we update
    the numberOfSmoothiesTillPrize variable
17. 46690 0:47 - 0:49
    to be this new value.
18. 48740 0:49 - 0:53
    This evaluates to ten minus ten,
19. 53010 0:53 - 0:58
    which is zero, so we essentially
    update this to have zero smoothies.
20. 58290 0:58 - 1:02
    That makes sense, because once you've
    reached ten smoothies, and you get
21. 61960 1:02 - 1:07
    a free one, your count goes back to zero
    and and you have to buy ten more again.
22. 66660 1:07 - 1:10
    So this has a value of zero,
    let's continue.
23. 70150 1:10 - 1:13
    Well, we've reached then end
    of this if block of code,
24. 73388 1:13 - 1:18
    and we skip over the else lock
    because we only do one or the other.
25. 78050 1:18 - 1:20
    And so we immediately go down here.
26. 80380 1:20 - 1:24
    In this last code statement, we add
    a log message that says, you currently
27. 84424 1:24 - 1:30
    have blank out of 10 smoothies
    needed for your next free smoothie.
28. 90010 1:30 - 1:34
    This blank here is actually a variable
    called numberOfSmoothiesTillPrize.
29. 94040 1:34 - 1:39
    And this currently has a value of zero,
    because we updated it here.
30. 98770 1:39 - 1:42
    So this message would say,
    you currently have zero out or
31. 102126 1:42 - 1:44
    ten smoothies until your next free one.
32. 104310 1:44 - 1:46
    Therefore, the answer is C.
33. 106360 1:46 - 1:50
    By stepping through the code,
    we got the message, Congratulations,
34. 109770 1:50 - 1:51
    you get a free smoothie!
35. 111340 1:51 - 1:53
    And we also saw the message,
36. 113200 1:53 - 1:57
    You currently have 0 out of 10
    smoothies until your next one.
37. 117150 1:57 - 2:01
    Option A, is incorrect, because we
    definitely did get a free smoothie.
38. 120700 2:01 - 2:04
    Option B, is incorrect because
    we updated the number of
39. 123560 2:04 - 2:06
    smoothies count back to zero.
40. 125690 2:06 - 2:09
    Nice job trying to recode that
    you didn't understand before and
41. 129258 2:09 - 2:11
    trying to pick the answer.
42. 131240 2:11 - 2:14
    Continue on to learn
    exactly what is going on.
