 ## C++ Design Patterns
 
-Software design patterns are general reusable solutions to problems which occur
-over and over again in object-oriented design enviroment. It is not a finished 
-design that can be transformed into source code directly, but it is template how
-to solve the problem. We can classify them by purpose into creational (abstract 
-the instantiation process), structure (how classes and objects are composed to form 
-larger structures) and behavioral patterns (the assignment of responsibilities between 
-objects).  
+C++ Implementation for 23 Design Patterns
 
 #### Creational Patterns 
 - [Abstract Factory], families of product objects
+![image](./images/AbstractFactory.png)
 - [Builder], how a composite object gets created
+![image](./images/Builder.png)
 - [Factory Method], subclass of object that is instantiated
+![image](./images/Factory.png)
 - [Prototype], class of object that is instantiated
+![image](images/Prototype.png)
 - [Singleton], the sole instance of a class 
+![image](./images/SingletonPattern.png)
 #### Structural Patterns
 - [Adapter], interface to an object
+![image](./images/Adapter.png)
 - [Bridge], implementation of an object 
+![image](./images/Bridge.png)
 - [Composite], structure and composition of an object
+![image](./images/Composite.png)
 - [Decorator], responsibilities of an object without subclassing
+![image](./images/Decorator.png)
 - [Façade], interface to a subsystem
+![image](./images/Facade.png)
 - [Flyweight], storage costs of objects
+![image](./images/Flyweight.png)
 - [Proxy], how an object is accessed (its location)
+![image](./images/Proxy.png)
 #### Behavioral Patterns
 - [Chain of Responsibility], object that can fulfill a request
+![image](./images/ChainOfResponsibility.png)
 - [Command], when and how a request is fulfilled
+![image](./images/Command.PNG)
 - [Interpreter], grammar and interpretation of a language
+![image](./images/Interpreter.PNG)
 - [Iterator], how an aggregate's elements are accessed
+![image](./images/Iterator.png)
 - [Mediator], how and which objects interact with each other
+![image](./images/Mediator.PNG)
 - [Memento], what private information is stored outside an object, and when 
+![image](./images/Memento.PNG)
 - [Observer], how the dependent objects stay up to date
+![image](./images/Observer.PNG)
 - [State], states of an object
+![image](./images/State.PNG)
 - [Strategy], an algorithm
+![image](./images/Strategy.PNG)
 - [Template Method], steps of an algorithm
+![image](./images/TemplateMethod.png)
 - [Visitor], operations that can be applied to objects without changing their classes
