Design Patterns using C++

Collection of various design patterns with example implementation in C++. Creational, Structural and Behavioral design patterns have been implemented. This also includes some of the commonly used Idiom in C++ programming. This is just to demonstrate the usage of the design patterns.

Note: Code is NOT optimized but is used as a part of knowledge sharing.

Creational Design Patterns

Pattern Name	Description
Factory Method	General object construction is replaced with a specific method
Abstract Factory	Group of related class without specifying concrete implementation
Builder	Stepwise construction of Complex objects
Prototype	Object constructed from a prototype
Singleton	Build Class with single instance

Structural Design Patterns

Pattern Name	Description
Adapter	Link Objects with incompatable interfaces/classes
Bridge	Decouples Abstraction and implementation
Composition	Build Object into tree like structures
Decorator	Adding additional Features to existing objects dynamically
Facade	For providing simple interface for complex libraries
Flyweight	Sharing the common data between multiple objects
Proxy	Controlled access to original object

Behavioral Design Patterns

Pattern Name	Description
Chain of Responsibility	Handle Request/Data by multiple configurable Handlers
PIMPL	Pointer to Implementation
Command	Convert Requests as Objects for Handling
Iterator	Traverse elements in collections without exposing
Mediator	Collabration between objects via a mediator
Memento	Saving and Restoring the state of an Object
Observer	Notify Events between objects having one to many relationship
State	Alter the Objects behaviour when internal parameters change
Strategy	Run-time changing of objects inturn changing behaviour
Template	Provides Skeleton in superclass allowing some of the steps to be overriden by subclasses
Visitor	Add new operations without changing the existing code

How to build the project

Clone the Repository

git clone https://github.com/jayavardhanravi/DesignPatterns.git

Open Solution file in Visual studio

In this project I used Visual Studio 2017. Choose and build the specific design pattern either in Debug or Release
