What is the difference between a Hash and an Array? +-->An array uses a consecutive integer index, while a Hash has a user-specified index that could be an integer, string, or any other object. + 2. When would you use an Array over a Hash and vice versa? +-->I would use an array for a simple one-dimensional collection that does not need any special indexing, i.e., is well suited to the consecutive-integer index of the Array. A Hash is better when you have a collection of objects with non-integer indexes.

Enumerable is a built in Ruby module, what is it? +--> A module is a self-contained block of Ruby code that you can "mix-in" to other Ruby programs.

A module may have a bunch of code, but it is not a class as it is not a collection of objects, but just code. + +Enumberable is a built-in Ruby module that contains multiple methods that build on the .each method in the base class. If you were to adapt the .each method to the specifics of your class, mixing-in Enumerable will give you great functionality such as .map, .include?, and find_all?. If you can define meaningful comparison functions over your class ("<", ">", etc.) Enumerable will bring along .min, .max, and .sort. + 4. Can you inherit more than one thing in Ruby? How could you get around this problem? +-->With Ruby, you can only inherit from one Superclass. However, you can bring in additional functionality by mixing-in modules. + 5. What is the difference between a Module and a Class? + +-->Both Classes and modules contain methods, classes, and constants, and constitute a namespace.

What is method_missing and how can it be used? +-->method_missing is the error message Ruby throws when you pass a method name to an object and that object does not have that method defined against it in its class or superclasses. It can be used in Duck Typing, where you test to see not if an object is of a particular type, but whether it responds to a desired method. "method_missing" indicates that it does not. 2. What is and Eigenclass and what is it used for? Where Do Singleton methods live? +-->An Eigenclass is also known as a singleton class. It is an "anonymous" class that Ruby creates immediately above an object (in terms of searching for methods). It is used to hold singleton methods that are tied only to that particular object. The singleton methods live in this Eigenclass or singleton class. 3. When would you use DuckTypeing? How would you use it to improve your code? +-->Duck typing is most useful in that you don't have to check types, which cleans up your code. It also means that the same method can apply to different types, such as an array and a string, which can allow code reuse. 4. What is the difference between a class method and an instance method? What is the difference between instance_eval and class_eval? +-->A class method is held in an eigenclass above the class, and is used to operate on the class itself. The instance method is held in the class, and operates on the instances of the class. 5. What is the difference between a singleton class and a singleton method? +-->A singleton class is an anonymous class over an object that holds the singleton methods available to that object. \ No newline at end of file From 3d62db44343554bb8fcbf5ca823c4e9d6537ce0b Mon Sep 17 00:00:00 2001 From: Neil Woodward Date: Mon, 24 Feb 2014 22:34:22 -0800 Subject: [PATCH 09/19] Week 7 Homework --- week7/homework/features/pirate.feature | 2 +- .../features/step_definitions/pirate.rb | 28 +++++++++++++++++++ 2 files changed, 29 insertions(+), 1 deletion(-) create mode 100644 week7/homework/features/step_definitions/pirate.rb diff --git a/week7/homework/features/pirate.feature b/week7/homework/features/pirate.feature index 7de1a0b..c4ef465 100644 --- a/week7/homework/features/pirate.feature +++ b/week7/homework/features/pirate.feature @@ -8,4 +8,4 @@ Heave to: The mighty speaking pirate Blimey!
