The Decorator design pattern allows an object to be decorated in different ways not by inheriting from another class but by adding features directly to this object.

It's main interest is to avoid multiplication of classes that would be almost the same as the main one.

The Prototype design pattern is used in order to clone an object.

Main goal to prototype design pattern is to create new objects with default values.

This cloning operation is actually a copy of an object and can be made with a shallow or a deep copy.

The Factory method design pattern is a really helpful one and a great dive into the world of design patterns.

In our example we are going to use an interface and some concrete classes.

If by reading this you are still interested in the concept, let's see the Factory method design pattern in this tutorial.

This Singleton design pattern is certainly the most known and maybe the most easiest to understand.

Its goal is to guarantee that an object will be created only once through all the program.

The Observer design pattern allows an object (often called Subject) to inform other objects (Observers) that an event has occurred.

It's particularly useful when you have data from a Subject but you don't know how this data will be used by the Observers.

The GridView is a bit like the ListView's sibling.

A lot of concepts are shared with those similar components.

The ListView is certainly one of the most used components by Android programmers in their applications.

Why? Because the concept is easy to understand and the result looks nice.

But a lot of tutorials are made with complicated ListView examples.

There are many ways to create a Makefile.

In this tutorial we are going to see how to generate a Makefile with CMake on Windows.

Indeed, CMake is a complex but interesting tool that can generate native Makefiles for the compiler of your choice.

Creating a library for your Google Test framework is a good practise.

It separates your main project, your library and your tests code.

A great way to deal with your dev team and your test team.

Visual Studio will be our IDE for this tutorial.

So let's get started.

Google Test framework is provided with a solution already generated that we can use with Visual Studio.

It's the gtest.sln file.

But to use it we have to accomplish some steps in order to having it working properly.

This is what we will see in this Google Test tutorial.

Let's get started.
