Week 2 - Homework

(10 total points)

• FORK this repository into your own account.
• CLONE your new repository onto your laptop.
• Change your current directory to your newly-cloned week2-homework folder (where this README file resides)

then, setup a new Rails application as follows:

1. Generate a new Rails application called "hw": rails new hw

2. Change your current directory to the newly-created hw subfolder: cd hw

3. Start your Rails server on port 3000, and verify that you can view the "Welcome Aboard" page in your browser (which is hopefully Google Chrome :-)

Now, you can earn 2 points for achieving each of the following challenges. All of these challenges must be implemented inside the hw app you just created.

Challenge #1: Links and Querystring Parameters

1. Your app must respond to the following URL: http://localhost:3000/greet and display the word, "Hello" inside of an h1 element: <h1>Hello</h1>

2. If a querystring parameter with the key salutation is present, then your app should use the querystring value as the message.

For example,

http://localhost:3000/greet?salutation=Howdy

must result in displaying "Howdy" inside of the h1 element.

Challenge #2: Submitting Data with a Form

1. Your app must respond to the following URL: http://localhost:3000/contact. This page should present a simple contact form, allowing the user to enter their first and last names.

2. When the user clicks the Submit button, the form should pass the data to: http://localhost:3000/contact_submitted which should display the information that had been entered.

Challenge #3: "Rock, Paper, Scissors" Game

The goal is to simulate a game of "Rock, Paper Scissors."

1. In this game, you visit a certain URL to begin: http://localhost:3000/rps. The human player chooses their weapon by clicking on a picture (or a simple text link) of a rock, a piece of paper, or a pair of scissors.
2. When the player clicks on their chosen weapon, the app should then have the computer randomly select a weapon and display the result. The player's choice, the computer's choice, and the winner should all be displayed. If it's a tie, the app should display "It's a tie!" instead of declaring a winner.
3. The page that displays the result must include a link to play again.

Challenge #4: "Craps" Dice Game

For a live example and instructions, see: http://jeffcohenonline.com/demos/dice

• Your URL To Start The Game: http://localhost:3000/dice
• Any other urls you might need are NOT required to match what's in the demo, but you can use that strategy if you like
• The page should contain an h1 element with the content, "Dice Game"

FINALLY, be sure to:

5. COMMIT and then SYNC (push) your changes back to your account.
6. VERIFY your code has been submitted by browsing to your GitHub.com account.

Grading: 2 points for each correct challenge, plus 2 points for overall code readability.

Happy coding!
