[MUSIC]

2
00:00:04,747 --> 00:00:08,280
Let's practice some basic Ruby to make
sure that everything that you've learned

3
00:00:08,280 --> 00:00:08,952
so far sticks.

4
00:00:08,952 --> 00:00:12,560
We'll review variables,
as well as simple input and output.

5
00:00:12,560 --> 00:00:14,210
If you're not familiar with these topics,

6
00:00:14,210 --> 00:00:18,530
check the Teacher's Notes attached to this
video for links where you can learn more.

7
00:00:18,530 --> 00:00:22,110
We're going to ask you to
build a simple Ruby program.

8
00:00:22,110 --> 00:00:25,440
Your program will play a fill-in-the-blank
word game with the user.

9
00:00:25,440 --> 00:00:30,230
You'll prompt them for a noun,
a verb, and so forth, just like this.

10
00:00:30,230 --> 00:00:31,953
So please enter a verb, jump.

11
00:00:31,953 --> 00:00:33,819
Please enter a noun, desk.

12
00:00:33,819 --> 00:00:35,454
Please enter an adjective.

13
00:00:35,454 --> 00:00:36,877
Let's say, quick.

14
00:00:36,877 --> 00:00:38,317
And another noun.

15
00:00:38,317 --> 00:00:39,880
Let's say, can.

16
00:00:39,880 --> 00:00:43,592
Then you'll use those stored words to
fill in blanks in several sentences and

17
00:00:43,592 --> 00:00:45,373
print the completed sentences out.

18
00:00:45,373 --> 00:00:48,012
The resulting story will probably
sound a little silly, and

19
00:00:48,012 --> 00:00:49,728
that's exactly the point of the game.

20
00:00:49,728 --> 00:00:54,207
It's pretty simple but it combines
several fundamental programming steps.

21
00:00:54,207 --> 00:00:57,390
The formatting on your printed
story may look a little strange.

22
00:00:57,390 --> 00:00:59,940
Don't worry about that while
you're coding your solution.

23
00:00:59,940 --> 00:01:03,942
When I show you my solution, I'll also
show you a new method you can go back and

24
00:01:03,942 --> 00:01:06,049
add to your program to clean up the output.

25
00:01:06,049 --> 00:01:08,355
I've attached a workspace to this video,

26
00:01:08,355 --> 00:01:12,790
which includes a game.rb starter file
with instructions as Ruby comments.

27
00:01:12,790 --> 00:01:14,100
You should open the workspace now.

28
00:01:15,270 --> 00:01:19,310
You can either use our in-browser editor,
or you can choose Download Workspace from

29
00:01:19,310 --> 00:01:22,040
the File menu, if you have Ruby
installed on your computer.

30
00:01:23,170 --> 00:01:26,440
Write your code in the game.rb file and
save your work.

31
00:01:26,440 --> 00:01:31,649
Then, switch to the terminal and
type ruby game.rb.

32
00:01:31,649 --> 00:01:33,790
That will run your completed game.

33
00:01:33,790 --> 00:01:36,940
The game should begin prompting for
words and print your story when it's done.

34
00:01:38,010 --> 00:01:40,288
I've linked to some videos
in the Teacher's Notes,

35
00:01:40,288 --> 00:01:41,967
which you can refer to if you get stuck.

36
00:01:41,967 --> 00:01:43,827
After you've written your program,

37
00:01:43,827 --> 00:01:47,900
you can proceed to the next video where
you can compare my solution to yours.

38
00:01:47,900 --> 00:01:48,450
Ready?

39
00:01:48,450 --> 00:01:49,830
Get started on your program.

40
00:01:49,830 --> 00:01:51,670
I'll show you my version
in the next video.
