# 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 = 35 # can test with <20, 20 <= moto_speed <= 55, >55 settings

if ( (moto_speed.to_f >= 20) && (moto_speed.to_f <= 55) )
  puts "Wheee!"
elsif (moto_speed.to_f > 55)
  puts "Your are way too fast!"
else
  puts "You're too slow!"
end

# Make a method that checks your moto speed when called

def check_speed (mph)
  case
    when (mph.to_f < 20)
      puts "You're too slow!"
  when ( mph.to_f >= 20) && ( mph.to_f<= 55)
      puts "Wheee!"
  when (mph.to_f > 55)
      puts "Your are way too fast!"
  end
end

#Test method
check_speed(19)
check_speed(20)
check_speed(55)
check_speed(56)


# Make a method to start your bike! It should print out "vrooom!"
# when it's called

# your code below:

def start_bike()
  puts "vrooom!"
end

#Test method
start_bike


# You're the leader of the pack.
# Create an Array of 3 motorcycle makes!

my_convoy = ["Yamaha", "Kawasaki", "BMW"]

# Loop through your convoy and print out each motorcycle's make
# Your code below:

my_convoy.each do |make|
  puts "#{make}"
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}

tom = { "name" => "tom", "helmet" => "white", "height" =>"175cm" }
dick = { "name" => "dick", "helmet" => "green", "height" =>"185cm" }
harry = { "name" => "harry", "helmet" => "blue", "height" =>"195cm" }

# my_gang = {
#   tom => { "name" => "tom", "helmet" => "white", "height" =>"175cm" },
#   dick => { "name" => "dick", "helmet" => "green", "height" =>"185cm" },
#   harry => { "name" => "harry", "helmet" => "blue", "height" =>"195cm" }
# }

my_gang = { :member1 => tom, :member2 => dick, :member3 => harry }

#Test hash contents..
puts my_gang

# Loop through your gang and print out each rider's
# name & helmet color using a block. Your code below:

my_gang.keys.each do |member|         # :member1, :member2, :member3
  member.keys.each do |person_data|  # tom, dick, harry
    person_data.keys.each do |data|      #
      puts data
    end
  end
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:


# 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

#   def initialize(name, moto_model)
#   end

#   def say_name(rider)
#   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 intialize(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 say_something
#     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:

Nice job on the !Quiz

For future reference you don't need a triple loop to go through your my_gang Hash.
Just use my_gang.each |key, value|
