I have a doubt [Ruby]

Question

[English]
When i wrote this code:

class Person
attr_accessor :name, :age
def initialiaze( name, age )
@name = name
@age = age
end
def change( n, a )
self.name = n
self.age = a
end
def show_info
puts('#{self.name} is #{self.age}')
end
end

p = Person.new("David",28)
p.change("Bob",42)
p.show_info

it appears me this:
Traceback (most recent call last):
2: from clases2.rb:17:in `<main>'
1: from clases2.rb:17:in `new'
clases2.rb:17:in `initialize': wrong number of arguments (given 2, expected 0) (ArgumentError)

Answer 1

it is initialize not initialiaze .
And put double quotes to output data .

single quotes won't evaluate expression .

Answer 2

Like Md Sayed said, you've misspelled it. It should be def initialize.

A method called initialize runs internally when you call .new on your Person class. If you want to take control of this method, you need to define it yourself.

In your case, Ruby doesn't recognise your arguments because you haven't defined the method correctly because of the misspelled method name. This is why the error message states that you've provided the wrong number of arguments to the initialize method. It says given 2 - that's the two you've given when calling .new - but it's expecting 0 because it thinks you haven't defined an initialize method.
