In Ruby,
Example:
In this example,
#ruby
instance variables are variables that belong to a specific instance of a class. They are prefixed with the @ symbol and are accessible within the instance methods of that class. Instance variables allow objects to maintain state and store information unique to each instance.Example:
Code
class Person
def initialize(name, age)
@name = name
@age = age
end
def say_intro
puts "Hello, my name is #{@name} and I am #{@age} years old"
end
end
# Create a new instance of Person
person1 = Person.new("John", 18)
# Call the say_intro method
person1.say_introIn this example,
@name is an instance variable of the Person class, representing the name of each Person object created. The initialize method is a constructor that sets the value of @name when a new Person object is created. The say_intro method uses the instance variable @name to give the intro of the person with their name and age when called.#ruby
