<h1 role="main">Tutorial: Creating a simple application</h1>
<p>In this tutorial, you will use the CDT to create a simple 'Hello World' application.
This tutorial describes the process of creating a new C++ project where the build is
automatically managed by the CDT, and running the program.</p>
<p><strong>NOTE</strong>: In earlier versions of the CDT, there were two separate project types:
Managed make (automatically generated a makefile)
and Standard make (required the user's makefile to build).
Now with CDT, you just select a project type, and that determines what build system to use.</p>
<p>To create a simple "Hello World" application using CDT, perform the following general steps:</p>
<ol>
<li><a href="#cdt_create">Creating a project</a></li>
<li><a href="#cdt_build">Reviewing the code and building the project</a></li>
<li><a href="#cdt_running">Running the application</a></li>
</ol>

<h2> Step 1: <a name="cdt_create"></a>Creating a project</h2>
<ol>
<li>Select <strong>File > New > Project</strong>.<br>
<br>
<img src="../images/cdt_w_basic02.png" alt="Select File > New > Project menu option" width="591" height="183">
<p><br>
</p>
</li>
<li>Select the type of project to create. For this tutorial, expand the <strong>C++</strong> folder and select <strong>C++ Project</strong> and click <strong>Next</strong>.<br>
<br>
<img src="../images/cdt_w_basic03a.png" alt="Select project type" width="525" height="500"><br>
<br>
</li>
<li>
<p>The <strong>C++ Project</strong> wizard opens.<br>
</p>
<p><img src="../images/cdt_w_basic04.png" alt="C++ project wizard" width="525" height="576"><br>
<br>By default, the CDT filters the <strong>Toolchain</strong> and <strong>Project types</strong> that it displays in those lists based on the language support for the C++ Project wizard you selected for this tutorial.</p>
<br>
<ol style="list-style-type: lower-alpha;">
<li>In the <strong>Project name</strong> field, type a name for the project, such as <strong>HelloWorld</strong>.
<p><br>
</p>
</li>
<li>From the <strong>Project type</strong> list, expand <strong>Executable</strong> and select <strong>Hello World C++ Project</strong>. This project type provides a simple Hello World application in C++, and the makefile is automatically created by the CDT.
<p><br>
</p>
</li>
<li>Select a required toolchain from the <strong>Toolchain</strong> list.
<p><br>
</p>
<p>A toolchain is a set of tools (such as a compiler, linker, and assembler) intended to build your project.
Additional tools, such as a debugger, can be associated with a toolchain.
There can be several toolchains available, depending on the compilers installed on your system.</p>
<p><br>
</p>
</li>
<li>Click <strong>Next</strong>. </li>
</ol>
<br>
</li>
<li>Specify the <strong>Basic Properties</strong> for the new project, such as your author, copyright, and source information, then click <strong>Next</strong>.<br>
<br>
<img src="../images/cdt_w_basic06a.png" alt="Basic properties of a project" width="525" height="576"><br>
<br>
</li>
<li>
<p>The <strong>Select Configurations</strong> page displays a list of configurations based on the project type and toolchain(s) selected earlier. <br>
<br>
<img src="../images/cdt_w_basic07.png" alt="Select configurations page" width="525" height="576"><br>
<br>
<strong>OPTIONAL</strong>: If you want to change the default project settings, click <strong>Advanced Setting</strong> to open the <a href="../reference/cdt_u_prop_all.htm">Project Properties</a> dialog for your new project allowing you change any of the project specific settings,
such as includes paths, compiler options, and libraries.<br>
<br>
</p></li>
<li><p>Click <strong>Finish</strong>.<br>
</p></li>
</ol>
<p><strong>NOTE</strong> If the <strong>C++ perspective</strong> is not currently set as the default, you are prompted to determined if you would like to this project to be associated with the C/C++ perspective. Click <strong>Yes</strong>.<br>
</p>
<p>A project is created with the default settings and a full set of configurations based on the project type and toolchain you selected.
You should now see the new project in <a href="../reference/cdt_u_project_explorer_view.htm">Project Explorer</a> view.</p>
<p> <img src="../images/cdt_w_basic12.png" alt="New project displayed in the Project Explorer view" width="423" height="283"></p>
<br>

<br>
<h2>Step 2: <a name="cdt_build" id="cdt_build"></a>Reviewing the code and building the project</h2>
<ol>
<li>From the <strong>Project Explorer</strong> view, double-click the .cpp file created for your project, for example, <span class="typewriter">HelloWorld.cpp</span>. You'll find it within the project "<span class="typewriter">src</span>" folder.<br>
<br>
<p>This file opens in a default editor. It contains C++ template code for the Hello World example project you selected earlier. In addition, the <a href="../reference/cdt_u_outline_view.htm">Outline</a> view has also been populated
with objects created from your code.<br>
<br>
<img src="../images/cdt_w_basic13.png" alt="C Editor with Outline view" width="731" height="333"><br>
<br>
<strong>NOTE:</strong> You can specify a different editor, and add or modify existing code templates in <strong>Window > Preferences</strong>.<br>
<br>
<strong>OPTIONAL</strong>: You can type additional code in this file, and then save the changes by clicking <span
style="font-weight: bold;">File > Save</span>, or pressing <strong>CTRL+S</strong>.<br>
<br>
Next, you will need to build your project before you can run it.<br>
<br>
</p>
</li>
<li>Build your project by pressing <strong>CTRL+B</strong>, or select the project in the <strong>Project Explorer</strong> view and select <strong>File > Build Project</strong>.
</p>
<p><br>
<strong>NOTE:</strong> If a build generates any errors or warnings, you can see those in the <a href="../reference/cdt_u_problems_view.htm">Problems</a> view. If you encounter difficulty, see the topics <a href="../concepts/cdt_c_build_over.htm">Building C/C++ projects</a> and <a href="../concepts/cdt_c_before_you_begin.htm">Before you begin</a><br>
.</p>
</li>
<li>Read through the build messages in the <a href="../reference/cdt_u_console_view.htm">Console</a> view.
The project should build successfully.</p>
<br>
<br>
<p>You will also see the <strong>Outline</strong> view has also been populated
with objects created from your code. If you select an item from the <strong>Outline</strong> view, the
corresponding text in the editor is highlighted.</p></li>
</ol>
<hr>
<br>
<h2>Step 3: <a name="cdt_running" id="cdt_running"></a>Running the application</h2>
<p>To run your application:</p>
<ol>
<li>Within the C/C++ Perspective, click <strong>Run > Run Configurations...</strong>.<p><br></p></li>
<li>Select <strong>C/C++ Application</strong>.<p><br></p></li>
<li>Click <strong>New</strong>.<br>
<p>A new Run Configuration is created. Its name and path to the executable are provided by the project ('Hello World' in our case).
</li>
<li>Click <strong>Run</strong>.<p><br></p>
<p>Now, you should see the Hello World application running in the <strong>Console</strong> view.
The <strong>Console</strong> also shows which application is running in a title bar.</p><br></li>
<li>You can click the other views to see the information that they contain.</li>
