Learn to Program (reading assigned for day 1) will be your bread and butter for learning basic ruby concepts. Here's a list of some other great online resources to help you perfect your ruby skills.

• Try Ruby
• Code Academy
• Ruby Monk

Note: You don't have to do all of these, they're just here to help you if you're struggling or if you're ahead and interested in learning concepts that are outside the scope of this class

Exercises

Note: All exercises must live inside of your s0203_exercises/firstname_lastname/d2 folder

While inside of your s0203_exercises directory, you can git add . then git commit -m "Helpful commit message here" and git push origin master to submit your homework to GitHub. (Don't forget to use git status along the way to check the state of your files in git)

Create (subl <filename> from terminal) a file named answers.md in your d2 folder. You will use markdown to add the answers from the questions below to your answers.md file. Check out this cheatsheet to learn the syntax, it's very straightforward. You can use the aid of an online editor like Dillinger as well.

Answer these questions in your answers.md file using markdown format

Some of these questions were not covered in our lecture today, it's up to you to do some research and figure out how to solve them.

1. What would you write in the terminal to assign the variable x to the value 5?
2. What is the datatype of "Matt"?
3. If we write x = 5 in our REPL (pry), is x a string?
4. What does this expression evaluate to? "YO" + "LO"
5. What does this expression evaluate to? "Cool".+("io")
6. What does this expression evaluate to? "bob" + 42
7. a = "Bat" & b = "woman" What does the expression, a + b, evaluate to?
8. If we write my_name = "50 Cent" then my_name = "Miley" What does this expression print? p my_name
9. rapper = "Jaydakiss" What would you type to get the first letter from the string "Jaydakiss"?
10. Get the first through 3rd elements from the "Jaydakiss" string.

Great work! Now add and commit your work then push it to GitHub :)
