+Instructions for Mid-Term submission and Git Review (10pts):
+ - Create a git repository for your answers
+ - Add and Commit as you work through the questions and programming problems
+ - Your git log should reflect your work, don't just commit after you have finished working
+ - Use .gitignore to ignore any files that are not relevant to the midterm
+ - E-mail me your ssh public key
+ - I will email you back with your repository name
+ - Add a remote to your git repository: [email protected]:RubyFall2013/YOURREPOSITORYNAME.git
+ - Push your changes to the remote
+ - After 6pm Tuesday November 19th you will not be able to push to your remote repository (or clone).
+
+ Questions (20pts):
+ - What are the three uses of the curly brackets {} in Ruby?
+ - What is a regular expression and what is a common use for them? 
+ - What is the difference between how a String, a symbol, a FixNum, and a Float are stored in Ruby?
+ - Are these two statements equivalent? Why or Why Not?
+   1. x, y = "hello", "hello"
+   2. x = y = "hello"
+- What is the difference between a Range and an Array?
+- Why would I use a Hash instead of an Array?
+- What is your favorite thing about Ruby so far?
+- What is your least favorite thing about Ruby so far?
+
+ Programming Problems (10pts each):
+ - Write a passing rspec file called even_number_spec.rb that tests a class called EvenNumber.
+    - The EvenNumber class should:
+       - Only allow even numbers
+       - Get the next even number
+       - Compare even numbers
+       - Generate a range of even numbers
+- Make the rspec tests in wish_list_spec.rb pass by writing a WishList class
+   - The WishList class should:
+      - Mixin Enumerable
+      - Define each so it returns wishes as strings with their index as part of the string
+
+Mid-Term Spec (50pts):
+- Make the tests pass.

 Please read: 
 Chapter 3 Classes, Objects, and Variables 
+
 p.86-90 Strings (Strings section in Chapter 6 Standard Types)
 
 1. What is an object?
+a instance of a class. 
 
 2. What is a variable?
+a reference to a object
 
 3. What is the difference between an object and a class?
+a class is a combination of state and methods. an object is a instance of that class ( class instance ).  
+
 
 4. What is a String?
+A sequence of characters.  
 
 5. What are three messages that I can send to a string object? Hint: think methods
+chomp, count, delete, empty? , length, upcase, downcase, split, squeeze! ... woah there are alot. 
+
 
 6. What are two ways of defining a String literal? Bonus: What is the difference between the two?
+
+single or double quotation marks. 
+
+single quotes 'foo', foo becomes the value. 
+For Double quotes, "foo\nbar" ruby looks for substitutions, interpolation "#{foo}" and escape sequences "Foo \nBar"
+
+also %q ( single quotes ), %Q ( double quotes ) 
+
+%q/foo bar/
+%Q!oh no #{crap}!
+
+you can choose a delimiter. 
+
+Finally here documents. 
+
+string = << HERE
+	some kinda text 
+	about something
+	i forgot what
+HERE
