  - What is the difference between how a String, a symbol, a FixNum, and a Float are stored in Ruby?
+Floats are saved by the same object id, saves them as a singleton above 32 bits it doesn’t freeze it anymore

 1. What is an object?
 
+An object is a data structure that interacts with its own code, in other words, anything we manipulate in Ruby.
+
 2. What is a variable?
 
+A variable labels and holds data, like an integer or a string.
+
 3. What is the difference between an object and a class?
 
+An object is a class instance and a class contains class instances. 
+Classes contain objects that interact with methods and each other.
+
 4. What is a String?
 
+A string is a sequence of characters that are sometimes printable. In Ruby, there are many built-in methods
+that can be used on strings.
+
 5. What are three messages that I can send to a string object? Hint: think methods
 
+String#split, String#scan, String#chomp.
+
 6. What are two ways of defining a String literal? Bonus: What is the difference between them?
+
+To define a String literal you can use single quotes (‘ ’), double quotes (“ “), %q, %Q, or here documents. 
+%q and %Q are the same as single quotes and double quotes. 
+Here documents are treated as a section of source code and they can be used to create multiline strings.

 Sharing Functionality: Inheritance, Modules, and Mixins
 
 1. What is the difference between a Hash and an Array?
+A Hash has key-value pairs that can be any object and an Array uses only integers as an index.  
 
 2. When would you use an Array over a Hash and vice versa?
 
+An Array is used when you have an ordered list and it's ok to have an integer for the index. Also, it's easier to use an Array for iteration. 
+A Hash is used when you want to store information using a key that is not an integer. 
+
 3. What is a module? Enumerable is a built in Ruby module, what is it?
+A module is a collection of constants and methods. Enumerable has methods used for searching and sorting collections (i.e. Hash and Array). 
 
 4. Can you inherit more than one thing in Ruby? How could you get around this problem?
+A class can only inherit from one parent class, but by using Mixin Modules you can simulate multiple inheritance. 
 
 5. What is the difference between a Module and a Class?

+Modules you can use across multiple classes. Modules are about functions and constants and classes are about objects and instances.

 1. What is a symbol?
 
+A symbol is a constant name that is guaranteed to be unique and contain the same value through out the entire program. 
+
 2. What is the difference between a symbol and a string?
 
+Symbols are immutable, where as strings are mutable. Symbols are often used as hash keys because they are immutable. 
+
 3. What is a block and how do I call a block?
 
+A block is code between do and end or between brackets. An iterator method can call a block. The format for a block is first you have a collection for the method to iterator over then you have the keyword “do” or a open curly bracket then the value to be passed in, then the code, and finally a closing curly bracket or and “end” keyword.  
+
 4. How do I pass a block to a method? What is the method signature?
 
+By using the keyword yield you can pass a block to a method. You can also pass parameters to a block and a method can receive values from a block using method. The method signature is the method name with the parameter list.   
+
 5. Where would you use regular expressions?
+
+You can use a regular expression to test a string for a matching pattern, to extract a matching pattern from a string, and substitution.

 1. How does Ruby read files?
 
+Ruby reads a line from a standard input or files specified when gets or file.gets is used. 
+There are also iterators you can use to read files. IO#each_byte iterates over 8-bit bytes from the IO object. IO#each_line calls the block with each line from the file. IO#foreach opens the file to read, calls the block on one line from the file then closes the file. IO#read gets an entire file into a string or into an array of lines.
+
 2. How would you output "Hello World!" to a file called my_output.txt?
 
+File.open(“my_output.txt”, “w”) do |file|
+    file.puts “Hello World!”
+end
+
+puts File.read(“my_output.txt”)
+
 3. What is the Directory class and what is it used for?
 
+the Directory class is a way to list files and directories in Ruby. You can make instances of the Dir class and you can iterate over an object of the Dir class.
+
 4. What is an IO object?
 
+An IO object is a way for a ruby program to write to or read from an external resource.
+
 5. What is rake and what is it used for? What is a rake task?
+
+Rake is an internal Domain Specific Language based in Ruby. Rake has libraries that make it easy to do tasks that are common during the build and deploy process. You can define a rake task to customize it or if you don’t define a rake task then it defaults to test.
