2. C++ classes - Wikipedia

   en.wikipedia.org/wiki/C++_classes

   C++ classes. A class in C++ is a user-defined type or data structure declared with any of the keywords class, struct or union (the first two are collectively referred to as non-union classes) that has data and functions (also called member variables and member functions) as its members whose access is governed by the three access specifiers ...

3. Composition over inheritance - Wikipedia

   en.wikipedia.org/wiki/Composition_over_inheritance

   Composition over inheritance (or composite reuse principle) in object-oriented programming (OOP) is the principle that classes should favor polymorphic behavior and code reuse by their composition (by containing instances of other classes that implement the desired functionality) over inheritance from a base or parent class. [2]

4. Rule of three (C++ programming) - Wikipedia

   en.wikipedia.org/wiki/Rule_of_three_(C++...

   Rule of three. The rule of three (also known as the law of the big three or the big three) is a rule of thumb in C++ (prior to C++11) that claims that if a class defines any of the following then it should probably explicitly define all three: [1] destructor. copy constructor. copy assignment operator. These three functions are special member ...

5. C++ - Wikipedia

   en.wikipedia.org/wiki/C++

   Therefore, C++ supports not just object-oriented programming, but other decomposition paradigms such as modular programming. It is generally considered good practice to make all data private or protected, and to make public only those functions that are part of a minimal interface for users of the class. This can hide the details of data ...

6. Class (computer programming) - Wikipedia

   en.wikipedia.org/wiki/Class_(computer_programming)

   In class-based programming, objects are created as instances of classes by subroutines called constructors, and destroyed by destructors. An object is an instance of a class as it can access to all data types (primitive as well as non primitive), and methods etc., of a class. Therefore, objects may be called a class instances or class objects.

7. C++ Standard Library - Wikipedia

   en.wikipedia.org/wiki/C++_Standard_Library

   Overview. The C++ Standard Library provides several generic containers, functions to use and manipulate these containers, function objects, generic strings and streams (including interactive and file I/O), support for some language features, and functions for common tasks such as finding the square root of a number.

8. Object-oriented programming - Wikipedia

   en.wikipedia.org/wiki/Object-oriented_programming

   Objects are instances of a class. Object-oriented programming ( OOP) is a programming paradigm based on the concept of objects, [1] which can contain data and code: data in the form of fields (often known as attributes or properties ), and code in the form of procedures (often known as methods ). In OOP, computer programs are designed by making ...

9. Inheritance (object-oriented programming) - Wikipedia

   en.wikipedia.org/wiki/Inheritance_(object...

   In object-oriented programming, inheritance is the mechanism of basing an object or class upon another object ( prototype-based inheritance) or class ( class-based inheritance ), retaining similar implementation. Also defined as deriving new classes ( sub classes) from existing ones such as super class or base class and then forming them into a ...
