Array not saving user input in ruby - ruby-on-rails

Question

This is what I have so far, but the array is not saving the first value if the user enters 2 or more car types. If I remove the car.get_ methods the program runs fine without saving the users input. Is there a method I am missing?
class Cars
def set_make(make)
end
def set_model(model)
end
def set_year(year)
end
array_of_cars = Array.new
print "How many cars do you want to create? "
num_cars = gets.to_i
puts
for i in 1.. num_cars
puts
print "Enter make for car #{i}: "
make = gets.chomp
print "Enter model for car #{i}: "
model = gets.chomp
print "Enter year of car #{i}: "
year = gets.to_i
c = Car.new
c.set_make(make)
c.set_model(model)
c.set_year(year)
array_of_cars << c
end
puts
puts "You have the following cars: "
for car in array_of_cars
print "#{car.get_year} #{car.get_make} #{car.get_model}"
end
end

Answer 1

Ok so the primary issue is that you calling the Car.new where the Car class is defined. You should not have an array of cars in the car class. You could try creating a Dealership class that has an array of cars then you could do something like this
class Dealership
attr_accessor :car_lot
def initialize
#car_lot = []
end
def add_car(car)
#car_lot << car
end
end
crazy_carls = Dealership.new
car1 = Car.new(make, model, year)
crazy_carls.add_car(car1)
crazy_carls.car_lot.each do |car
print "#{car.get_year} #{car.get_make} #{car.get_model}"
end
You need to refactor the car class a good deal first though, look into how to use the initialize method, attr_accessor, and instance variables.
