Description: An instance variable is a fundamental concept in object-oriented programming (OOP) that refers to a variable defined within a class and is unique to each instance of that class. This means that each object created from the class has its own copy of the variable, allowing each object to maintain its own state and behavior. Instance variables are used to store data that is specific to each object, enabling programmers to model real-world entities more effectively. For example, in a ‘Car’ class, instance variables might include ‘color’, ‘make’, and ‘model’, where each car created from this class can have different values for these variables. Instance variables are typically accessed through instance methods, ensuring that access and modification of their values are done in a controlled and encapsulated manner, thus promoting data integrity and code modularity.
