Ruby - Classes and Objects

Identify the error in this Ruby class definition:

class Car
  def initialize(make, model)
    make = make
    model = model
  end
end

car = Car.new("Toyota", "Corolla")
puts car.make

AThe initialize method should not have parameters.

BThe puts statement should be puts car.model

CThe class name should be lowercase.

DInstance variables are not assigned; should use @make and @model.

Step-by-Step Solution

Solution:

Step 1: Check variable assignment in initialize
The code assigns local variables make = make and model = model, which do nothing to the object.
Step 2: Correct usage of instance variables
To store values in the object, it should assign @make = make and @model = model.
Final Answer:
Instance variables are not assigned; should use @make and @model. -> Option D
Quick Check:
Use @variable to store data in object [OK]

Quick Trick: Use @ before variable to save it in the object [OK]
