What are instance variables?

Can you explain what instance variables are in programming?

Sure! Instance variables are attributes that belong to a specific instance of a class. They hold data unique to each object.

How do instance variables differ from class variables?

Class variables are shared among all instances of a class, while instance variables are unique to each object.

Can you give me an example of how to use instance variables?

Of course! In Python, you can define an instance variable in the __init__ method like this: self.variable_name = value.

Are instance variables private by default?

No, instance variables are public by default in most programming languages, but you can make them private using naming conventions.
