I am creating a ShoppingCart class , when the shopping cart is filled with 5 or more items it takes a 10 percent discount. I am having trouble on the prints_cart method of class.
class ShoppingCart attr_reader :name
def initialize(name)
@name = name
@items = []
end
def add_items(item)
@items.push(item)
end
def total
total = 0.0
@items.each do |item|
total += item.price
end
if @items.length < 5
return total
else @items.length >= 5
return total - (total * 0.10)
end
end
def to_s
"Name: #{name}, Total: #{sprintf("%0.2f", total)}"
end
def print_cart
puts "#{name}'s Shopping Cart"
puts "-" * 40
puts "Item".ljust(30) + "Price".rjust(10)
add_items(item).each do |item|
puts add_items.name.ljust(30) + sprintf("%0.2f", add_items.price).rjust(10)
end
puts "-" * 40
puts "Total:".ljust(30) + sprintf("%0.2f", total).rjust(10)
puts "-" * 40
end
end
class Items def initialize(name, price) @name = name @price = price end end
banana = Items.new("Banana", 10) orange_juice = Items.new("Orange Juice" , 10) rice = Items.new("Rice", 1) vacuum_cleaner = Items.new("Vacuum Cleaner", 150) anchovies = Items.new("Anchovies" , 2) shopping_cart = ShoppingCart.new("Joseph") shopping_cart.add_items(banana) shopping_cart.add_items(orange_juice) shopping_cart.add_items(rice) shopping_cart.add_items(vacuum_cleaner) shopping_cart.add_items(anchovies) shopping_cart.print_cart
ClassAssignment.rb:34:in print_cart': undefined local variable or method
