#     
# This is our first week's !quiz Let's find out what we know.
# 
 
# The ideal range of your motor cycle speed 20 - 55. Over 55 is SCAREE!
# Check if your moto_speed is within that range using boolean (&&, ||)
# operators and comparison operators (== =< >= !=)
 
# if your moto_speed variable is in the right range print out a good
# message, aka "Wheee!" Otherwise print out an appropriate response.
# Your code goes below:

moto_speed = 60

if moto_speed >= 20 && moto_speed <= 55
  puts "Whee! We're cruising along at #{moto_speed} mph."
elsif moto_speed < 20
  puts "Umm...going a little slow, aren't we?"
else
  puts "AAAAAAAHHHHHHH! We're all gonna die!"
end
 
# Make a method that checks your moto speed when called
 
def check_speed(mph)
  if mph >= 20 && mph <= 55
    puts "Whee! We're cruising along at #{mph} mph."
  elsif mph < 20
    puts "Umm...going a little slow, aren't we?"
  else
    puts "AAAAAAAHHHHHHH! We're all gonna die!"
  end
end

check_speed(moto_speed )
 
# Make a method to start your bike! It should print out "vrooom!"
# when it's called
 
# your code below:
def moto_start
  puts 'Vrooom!'
end
 
# You're the leader of the pack. 
# Create an Array of 3 motorcycle makes!
 
my_convoy = %w(Triumph Harley Honda)
 
# Loop through your convoy and print out each motorcycle's make
# Your code below:
my_convoy.each do |bike|
  puts bike
end

 
# You need to keep track of your gang. 
# Create 3 separate Hashes containing riders' info. like so:
# fred = { name, helmet, height }
# Then a larger Hash containing all riders
# my_gang = {rider hashes}
jim = {
  name: 'Jim MacKinnon',
  helmet: 'black',
  height: "5'9\""
}

steve = {
  name: 'Steven Sloan',
  helmet: 'bandana',
  height: "5'9\""
}

amy = {
  name: 'Amy Higgins',
  helmet: 'red',
  height: "5'2\""
}

my_gang = { jim: jim, steve: steve, amy: amy}
 
# Loop through your gang and print out each rider's 
# name & helmet color using a block. Your code below:
my_gang.each do |k,v|
  puts "Name: #{v[:name]}, Helmet: #{v[:helmet]}"
end

# Now for each rider add their motorcycle to their Hash, 
# assume they are in the same order as your Array
# use a loop. Your code below:
i = 0
my_gang.each do |k, v|
  v[:moto] = my_convoy[i]
  i += 1
end
 
# Define an Class to represent each gang member 
# It should include methods to set their name and motorcyle make
# When say_name(name) is called the rider's name is printed out
 
class Rider
  attr_accessor :name, :moto_model
 
  def initialize(name, moto_model)
    @name = name
    @moto_model = moto_model
  end
 
  def say_name
    puts @name
  end
end
 
# A fellow student is noticing that instances of his new Foo class are missing
# their @bar instance variable
class Foo
  attr_reader :bar
 
  def initialize(bar)
    @bar = bar
  end
end
 
foo = Foo.new('value of bar')
foo.bar # TODO value is missing!
 
# Fix this code so it prints “hello”
class Bar
  def hello
    puts 'hello'
  end
end
 
bar = Bar.new
bar.hello
 
# Final Challenge:
# 1. initialize 3 new instances of class Rider
# 2. add these to a new Hash
# 3. loop through the riders Hash and call say_name for each rider.
# Hint: you will need an attr_accessor in Rider to call it's method
# Your code below:

tom = Rider.new('Tom', 'Harley')
dick = Rider.new('Dick', 'Harley')
harry = Rider.new('Harry', 'Crotch Rocket')

new_riders = {
  tom: tom,
  dick: dick,
  harry: harry
}

new_riders.each do |key, value|
  value.say_name
end

Well done! It looks like you've really got the concepts we went over this week.
