# code here
town.delete("Belle")
town|guests:|("Belle")
Assume you have an array of strings representing friend's names:
friends = ["Chip Potts", "Cogsworth", "Lumière", "Mrs. Potts"]
Using .each
AND string interpolation, produce output (using puts
) like so:
Belle is friends with Chip Potts
Belle is friends with Cogsworth
Belle is friends with Lumière
Belle is friends with Mrs. Potts
Write your code here:
# code here
friends.each do |name|
puts "Belle is friends with #{name}"

Create ruby classes for Animal

Each Animal
should have:
- a

instance method - Getter and setter for
name
Create a new Animal
instance with the name "Pumba"
Make the Lion

Each lion should have:
- a
king
attribute which is a boolean- If the instance's
name
isSimba
make theking
attribute true
- If the instance's
Create a new lion instance with the name simba
# code here
class Animal
attr_accessor :name
def intialize(name,greet)
@name = name
def greet
puts @name
end
end
hog = Animal.new(pumba)
