Attributes are the class member variables, the data, fields or other properties that define the class state. Methods are the functions of a class, the operations that define its behaviour, typically working in conjunction with the class member attributes to either alter the class state (mutators) or query the class state (accessors). Special methods such as the class constructors, its destructor and conversion operators are invoked indirectly through compiler-generated code while all others are called directly via programmer-generated code.
What else can I help you with?
What Grouping objects along with their attributes and methods into a class is called?
Composition.
Why inherit function is not called?
Inherit is not a function. It is a class derivation where some of the methods and attributes of the new class inherit from a parent class.
How do I convert a code to only having one class but also having a player and enemy working off of the one class in the python programming language?
To convert your code to use a single class for both the player and enemy in Python, you can create a class that includes attributes and methods common to both entities. For example, define attributes like name, health, and damage, and methods for actions like attack() and take_damage(). Then, instantiate objects of this class for the player and enemy, differentiating them by their specific attributes or behaviors. You can use parameters in the class constructor to set unique values for each instance.
Attributes of a class are also known as?
Attributes of a class are also known as properties or fields. They define the characteristics or data that instances of the class will have. In object-oriented programming, these attributes can store information specific to an object created from the class.
What are apex classes?
Apex is a strongly typed, object-oriented programming language. A class is a template or blueprint from which objects are created. An Apex Class is a library of attributes and methods and serves as a blueprint to create Apex objects.

What is meant by inheritance in c plus plus language?
Inheritance in C++ and in other Object Oriented languages is the creation of a class that incorporates a different class. The child (or derived) class "inherits" all of the elements (attributes and methods) of the parent (or base) class. Depending on the design of the base class, the derived class can use methods and attributes of the base class as if they were its own. Typically, however, attributes of the base class are private to the base class and inaccessible to the derived class so as to maintain class hierarchy and data encapsulation.
How can a base class protect derived classes so that changes to the base class will not affect them explain with example?
In order for a base class to protect derived classes, so that changes to the base class do not affect the derived classes, you must make sure that the public interface exposed by the base class does not change when the implementation of those public methods do change. You can also prevent inadvertant access to the base class attributes from the derived class, by making them private. class base { public: base(...) {...}; /* constructor */ base~(...) {...}; /* destructor */ method(...) {...}; /* other public methods */ private: ... etc. } class child : base { public: ... private: ... } So long as the calling sequence and functionality (interface) of the base class public methods do not change, the implementation of those public methods can change, and the private methods and attributes can change, without impacting any child class.

When you define a c plus plus class what items are considered part of the interface?
The interface of a C++ class is the public methods and attributes that are exposed by the class. In a pure abstract base class, the interface is enforced by the compiler in each of the derived child classes.
Attributes of a class are also known as?
Attributes of a class are also known as properties or fields. They define the characteristics or data that instances of the class will have. In object-oriented programming, these attributes can store information specific to an object created from the class.
How do you draw the class diagram for courier service?
To draw a class diagram for a courier service, identify the main entities involved, such as Courier, Customer, Package, Delivery, and Payment. Define the attributes and methods for each class; for instance, the Courier class might have attributes like courierID, name, and vehicleType, while Package might include weight, dimensions, and status. Establish relationships between the classes, such as a one-to-many relationship between Customer and Package, and a many-to-one relationship between Delivery and Courier. Use UML notation to represent these classes, their attributes, methods, and relationships visually.
What is a subclass and when is a subclass of use in data modeling?
A subclass is a specialized version of a class that inherits attributes and methods from its parent class. In data modeling, a subclass is useful for representing entities that have additional attributes or behaviors that are specific to a subset of instances of the parent class. Subclasses help organize data more efficiently and allow for more specific modeling of a system.

Can you have inheritance without polymorphism?
Yes. Inheritance and polymorphism are two different things. Inheritance is when the attributes and methods of a class are inherited by a deriving class that creates a more specialized type. Polymorphism is when two methods exist with the same name, differing only in argument types, or in class type. The former type, argument types, is an example of ad-hoc polymorphism that does not even require a class.
Represents a particular type of object in the real world?
A class in object-oriented programming represents a blueprint for creating objects that share common characteristics and behavior in the real world. It defines the attributes and methods that objects of that class will have.
