Let's practice some basic Ruby to make sure that everything that you've learned 0:04

so far sticks. 0:08

We'll review variables, as well as simple input and output. 0:08

If you're not familiar with these topics, 0:12

check the Teacher's Notes attached to this video for links where you can learn more. 0:14

We're going to ask you to build a simple Ruby program. 0:18

Your program will play a fill-in-the-blank word game with the user. 0:22

You'll prompt them for a noun, a verb, and so forth, just like this. 0:25

So please enter a verb, jump. 0:30

Please enter a noun, desk. 0:31

Please enter an adjective. 0:33

Let's say, quick. 0:35

And another noun. 0:36

Let's say, can. 0:38

Then you'll use those stored words to fill in blanks in several sentences and 0:39

print the completed sentences out. 0:43

The resulting story will probably sound a little silly, and 0:45

that's exactly the point of the game. 0:48

It's pretty simple but it combines several fundamental programming steps. 0:49

The formatting on your printed story may look a little strange. 0:54

Don't worry about that while you're coding your solution. 0:57

When I show you my solution, I'll also show you a new method you can go back and 0:59

add to your program to clean up the output. 1:03

I've attached a workspace to this video, 1:06

which includes a game.rb starter file with instructions as Ruby comments. 1:08

You should open the workspace now. 1:12

You can either use our in-browser editor, or you can choose Download Workspace from 1:15

the File menu, if you have Ruby installed on your computer. 1:19

Write your code in the game.rb file and save your work. 1:23

Then, switch to the terminal and type ruby game.rb. 1:26

That will run your completed game. 1:31

The game should begin prompting for words and print your story when it's done. 1:33

I've linked to some videos in the Teacher's Notes, 1:38

which you can refer to if you get stuck. 1:40

After you've written your program, 1:41

you can proceed to the next video where you can compare my solution to yours. 1:43
