What is the difference between an instance variable and a class variable? Ans. In object-oriented programming, instance variables and class variables are two types of variables that can be declared within a class. The main difference between them is that instance variables are associated with an instance of a class, while class variables are associated with the class itself.Key differences between instance variables and class variables:a) Scope Instance variables are only accessible within the instance of the class in which they are defined, whereas class variables are accessible throughout the entire class.b) Lifetime Instance variables are created when an instance of the class is created and are destroyed when the instance is destroyed, whereas class variables exist for the entire lifetime of the program.c) Memory allocation Instance variables are allocated memory each time an instance of the class is created, whereas class variables are allocated memory only once when the class is loaded.d) SharingEach instance of a class has its own copy of instance variables, while class variables are shared by all instances of the class. - Study24x7
