  2. Input/output (C++) - Wikipedia

    en.wikipedia.org/wiki/Input/output_(C++)

    In the C++ programming language, input/output library refers to a family of class templates and supporting functions in the C++ Standard Library that implement stream-based input/output capabilities. [1] [2] It is an object-oriented alternative to C's FILE-based streams from the C standard library. [3] [4]

  3. Object pool pattern - Wikipedia

    en.wikipedia.org/wiki/Object_pool_pattern

    An object pool design pattern may be deemed desirable in cases such as these. The object pool design pattern creates a set of objects that may be reused. When a new object is needed, it is requested from the pool. If a previously prepared object is available, it is returned immediately, avoiding the instantiation cost.

  4. Composition over inheritance - Wikipedia

    en.wikipedia.org/wiki/Composition_over_inheritance

    The C++ examples in this section demonstrate the principle of using composition and interfaces to achieve code reuse and polymorphism. Due to the C++ language not having a dedicated keyword to declare interfaces, the following C++ example uses inheritance from a pure abstract base class.

  5. Observer pattern - Wikipedia

    en.wikipedia.org/wiki/Observer_pattern

    The observer design pattern is a behavioural pattern listed among the 23 well-known "Gang of Four" design patterns that address recurring design challenges in order to design flexible and reusable object-oriented software, yielding objects that are easier to implement, change, test and reuse.

  6. Modern C++ Design - Wikipedia

    en.wikipedia.org/wiki/Modern_C++_Design

    Modern C++ Design: Generic Programming and Design Patterns Applied is a book written by Andrei Alexandrescu, published in 2001 by Addison-Wesley. It has been regarded as "one of the most important C++ books" by Scott Meyers. [1] The book makes use of and explores a C++ programming technique called template metaprogramming. While Alexandrescu ...

  7. Design Patterns - Wikipedia

    en.wikipedia.org/wiki/Design_Patterns

    It has been influential to the field of software engineering and is regarded as an important source for object-oriented design theory and practice. More than 500,000 copies have been sold in English and in 13 other languages. [1] The authors are often referred to as the Gang of Four (GoF). [2] [3] [4] [5]

  8. Bridge pattern - Wikipedia

    en.wikipedia.org/wiki/Bridge_pattern

    The Bridge design pattern is one of the twenty-three well-known GoF design patterns that describe how to solve recurring design problems to design flexible and reusable object-oriented software, that is, objects that are easier to implement, change, test, and reuse. [1] What problems can the Bridge design pattern solve? [2]

  9. Mediator pattern - Wikipedia

    en.wikipedia.org/wiki/Mediator_pattern

    The mediator [1] design pattern is one of the twenty-three well-known design patterns that describe how to solve recurring design problems to design flexible and reusable object-oriented software, that is, objects that are easier to implement, change, test, and reuse.
