chpt 11 notes :Inheritance and Composition in Object-Oriented Programming

These flashcards cover key concepts of inheritance and composition in object-oriented programming based on the lecture notes.

Inheritance

An 'is-a' relationship allowing new classes to be created from existing classes.

Derived Class

A new class created from an existing class, inheriting properties from the base class.

Base Class

The original class from which derived classes are created.

Single Inheritance

A derived class that has a single base class.

Multiple Inheritance

A derived class that has more than one base class.

Public Inheritance

All public members of the base class are inherited as public members by the derived class.

Composition

A 'has-a' relationship where one or more member(s) of a class are objects of another class type.

Encapsulation

Combines data and operations on data in a single unit.

Polymorphism

The ability to use the same expression to denote different operations.

Virtual Functions

Functions in C++ that allow run-time selection of appropriate member functions.

Destructors

Methods that deallocate dynamic memory allocated by objects of a class.

Constructor

A special method used to initialize objects when they are created.

Scope Resolution Operator (::)

Used to specify which class's member function is being referred to when overriding.

Access Specifiers

Modifiers that determine how members of a class can be accessed (public, protected, private).

UML Class Diagram

A standardized way to visualize the design of a system, showing classes and their relationships.

Member Initialization List

A list used in constructors to initialize member variables before the constructor body executes.

I/O Stream Classes

Classes such as istream and ostream used for handling input and output operations.
