What are the three major class features?

The Answer is The question "What are the three major class features?" is somewhat ambiguous as it does not specify the context or subject matter to which it refers. However, I will provide an answer based on a common interpretation within the realm of object-oriented programming (OOP), as classes are a fundamental concept in this area.

In object-oriented programming, a class is a blueprint for creating objects (a particular data structure), providing initial values for state (member variables or attributes), and implementations of behavior (member functions or methods). The three major class features in OOP are:

1. **Encapsulation**: Encapsulation is the mechanism of hiding the internal state of an object and requiring all interaction to be performed through an object's methods. It protects the integrity of the object by preventing external entities from directly manipulating its state. Instead, objects expose interfaces (methods) that allow controlled interaction with their internal state.

2. **Inheritance**: Inheritance is a way to form new classes using classes that have already been defined. The new classes, known as derived classes, inherit attributes and behavior from the existing classes, which are referred to as base classes. Inheritance allows for code reuse and can lead to a hierarchical relationship between classes.

3. **Polymorphism**: Polymorphism allows for the use of a single interface to represent different underlying forms (data types). In OOP, it means that a base class reference can point to a subclass object and that a method can perform different behaviors based on the object it is acting upon. This is often achieved through method overriding, where a method in a subclass has the same name and signature as a method in the parent class but implements different functionality.

These features work together to provide a robust framework for modeling complex systems and allow for code that is more modular, reusable, and easier to maintain.
