TECH603 Day 2 Warmup

warmup.rb

# 1. Create a `day_2` directory under the course directory.
# Check!

# 2. Save this file under the new folder as `warmup.rb`.
# Check!

# 3. Assign your favorite vacation location to a variable called `destination`.
destination = "Spain"

# 4. Assign the number of days you'd like to visit to a variable called 
#    `duration`.
duration = 100

# 5. Assign any floating point number to a variable named `price`. 
price = 1.23

# 6. Output the following message:
#      I would like to visit _ for _ days, and pay only _ for the whole trip.
puts "I would like to visit #{destination} for #{duration} days, and pay only #{price} for the whole trip."

puts "I would like to visit " + destination + " for " + duration.to_s + " days, and pay only " + price.to_s + " for the whole trip."

# 7. Add each of the previous variables to a collection.
vacation = [destination, duration, price]

# 8. Iterate through the collection and output each item.
vacation.each do |item|
  puts item
end

for item in vacation
  puts item
end

i = 0
while i <= vacation.size
  puts vacation[i].inspect
  i = i + 1
end

# 9. Create a dictionary called `vacation`. Use the previous variable names as 
#    keys and assign the values.
vacation = {
  "destination" => "Spain",
  "duration" => 100,
  "price" => 1.23
}

vacation2 = {
  :destination => "Spain",
  :duration => 100,
  :price => 1.23
}

vacation3 = {
  destination: "Spain",
  duration: 100,
  price: 1.23
}

# 10. Using the dictionary from the previous step, output the following message:
#       I would like to visit _ for _ days, and pay only _ for the whole trip.
puts "I would like to visit #{vacation["destination"]} for #{vacation["duration"]} days, and pay only #{vacation["price"]} for the whole trip."


# 11. Create a function called `yell`. It should take a single argument and 
#     return an uppercase version of the input.
def yell(message)
  string_message = message.to_s
  return string_message.upcase
end

puts yell("hello")
puts yell(250)
puts yell(1.23)
