A Symbol is a fixed name in ruby and is stored as an integer, so it takes up much less space than a string. A FixNum is an integer in Ruby and does not change its value. It is stored the same way as a symbol (you can think of symbols as Fixed Strings). Floats can have their value change and are stored like a string: each byte of the float is stored and can change individually (This has changed with Floats in Ruby 2.0.0 - floats with a precision of less than 32 bits are now stored like Fixnum and retain the same object_id for subsequent calls. Also, floats with greater than 32 bits in their decimal are rounded down to the closest fixed float of 32 bits. You should play with this in irb with Ruby 1.9.3 and Ruby 2.0.0 to see the difference.) + + - Are these two statements equivalent?

It does not store every element of the sequence, only the min and max. An array is an ordered list of many objects.

No, but you can use modules as mixins to get around this limitation. + +5. What is the difference between a Module and a Class? A module cannot have objects created from it as a class can. +======= +An array is an ordered list of items that are referenced by their index (order), a hash is a collection of items that can be referenced by a key and have no order. + +2. When would you use an Array over a Hash and vice versa? +When the items have an inherent order I would use an array, when I want to reference the items in my collection by a name or key and their order does not matter I would use a hash. + +3. What is a module? Enumerable is a built in Ruby module, what is it? +A module is a way to group code that you can use across multiple classes. Enumerable is a Ruby module that provides collection functionality; iteration, searching, and sorting. It requires an implementation of the each method. + +4. Can you inherit more than one thing in Ruby? How could you get around this problem? +No, multiple inheritance is not allowed in Ruby. You can include multiple modules if you wanted to mix-in different functionality into your code. Code that is related with a hierarchical nature should be subclassed (inherited). A class can only have 1 direct parent, but can have lots of ancestors. + +5. What is the difference between a Module and a Class? +A class can be instantiated into an object, a module cannot. A module is code that can be used across many classes. +>>>>>>> 9438bd77063c16f253d2a0b3692ccf1a278f3a40 diff --git a/week2/homework/simon_says.rb b/week2/homework/simon_says.rb new file mode 100644 index 0000000..356867b --- /dev/null +++ b/week2/homework/simon_says.rb @@ -0,0 +1,23 @@ +module SimonSays + + def echo input + input + end + + def shout input + input.upcase + end + + def repeat input, n = 2 + ([input] * n ).join(' ') + end + + def start_of_word input, n + input.slice(0,n) + end + + def first_word sentance + sentance.split.first + end + +end \ No newline at end of file diff --git a/week2/homework/simon_says_spec.rb b/week2/homework/simon_says_spec.rb index 7f329e5..264266f 100644 --- a/week2/homework/simon_says_spec.rb +++ b/week2/homework/simon_says_spec.rb @@ -44,4 +44,4 @@ it "should tell us the first word of 'oh dear' is 'oh'" do first_word("oh dear").should == "oh" end -end +end \ No newline at end of file diff --git a/week3/exercises/book.rb b/week3/exercises/book.rb index c13e4d4..7f89250 100644 --- a/week3/exercises/book.rb +++ b/week3/exercises/book.rb @@ -1,7 +1,29 @@ -class Book +$global_hello = "hi there" - def pages - - end +module Library + class Book + HELLO = "hello I shouln't change..." + + attr_accessor :pages, :title + + @@library_count = 0 + + def self.library_count + @@library_count + end + + def initialize pages = 0, title = "N/A" + @pages = pages + @title = title + @@library_count += 1 + end + + def happy + $global_hello = "hello" + "There are #{@pages} happy pages in this book" + end + + + end end \ No newline at end of file diff --git a/week3/exercises/book_spec.rb b/week3/exercises/book_spec.rb index 72bc203..a747ba4 100644 --- a/week3/exercises/book_spec.rb +++ b/week3/exercises/book_spec.rb @@ -1,10 +1,33 @@ require './book.rb' describe Book do - - it "should have a pages" do - book = Book.new - book.should respond_to "pages" + + before :each do + @book = Book.new 542, "Programming Ruby" + end + + context "::library_count" do + it "should tell us how many books are in our library" do + 34233.times{ Book.new } + Book.library_count.should eq 34234 + end end + context "#pages" do + it "should have a pages" do + @book.should respond_to "pages" + end + + it "should allow us to get the number of pages" do + @book.pages.should eq 542 + end + end + + context "#title" do + it "should let us read the title" do + @book.title.should eq "Programming Ruby" + end + end + + end \ No newline at end of file diff --git a/week3/exercises/human.rb b/week3/exercises/human.rb new file mode 100644 index 0000000..51c2855 --- /dev/null +++ b/week3/exercises/human.rb @@ -0,0 +1,6 @@ +require_relative 'named_thing' +require_relative 'other_thing' +class Human + include NamedThing + include OtherThing +end \ No newline at end of file diff --git a/week3/exercises/monster.rb b/week3/exercises/monster.rb index 013c3d2..9293138 100644 --- a/week3/exercises/monster.rb +++ b/week3/exercises/monster.rb @@ -11,4 +11,10 @@ def initialize(noc, legs, name="Monster", vul = [], dangers = []) @dangers = dangers @legs = legs end + + def attack!

What is method_missing and how can it be used? +<<<<<<< HEAD +If the interpreter can’t find the method anywhere up the object’s chain of inheritance, it will go back to the object and call another method called method_missing(). Just like with the first method, the interpreter looks for method_missing() in the object’s methods, then the object’s class’s instance methods etc. until reaches the Object class where method_missing() is defined and will raise a NoMethodError error. +By defining method_missing() within a class, it’s possible to change this default behaviour for some pretty useful effects. method_missing() is passed two arguments; the name of the missing method (as a symbol) and array of its arguments. +2. What is and Eigenclass and what is it used for? Where Do Singleton methods live? +The terms "eigenclass" and "singleton class" are used interchangeably in the context of ruby. +The singleton is a class with only one object. It does not exist until it is accessed. +3. When would you use DuckTypeing? When I want to dynamically change the behavior of a given class object. +How would you use it to improve your code? Whenever I need to use an object but need some different behavior. I would change the methods in the object. +4.
