Explanation:
Classes are a fundamental concept in object-oriented programming that serve as blueprints for creating objects. One of the key benefits of using classes is that they allow for the creation of multiple instances (objects) of a data structure, each with its own set of attributes and behaviors. This capability enables developers to model real-world entities more accurately and to manage the complexity of the software more effectively. Each instance of a class can have different values for its attributes, while still sharing the same methods defined in the class. This promotes code reuse and consistency, as common functionality can be defined once in the class and used by all instances. Additionally, classes support inheritance, encapsulation, and polymorphism, which further enhance the flexibility, maintainability, and scalability of the software.
