<h1>Creating your C++ file</h1>
|
|
|
|
<p>You can begin coding your HelloWorld program. The .cpp file that you
|
|
create will be saved in the project folder you just created
|
|
<a href="cdt_w_newproj.htm">Creating your project</a>.</p>
|
|
|
|
<p>Files are edited in the C/C++ editor located to the right of
|
|
the C/C++ Projects view. The left margin of the C/C++ editor, called the marker
|
|
bar, displays icons for
|
|
items such as bookmarks, breakpoints, and compiler errors and warnings.</p>
|
|
|
|
<p>For more information about:</p>
|
|
<ul>
|
|
<li>The marker bar, see <b>Workbench User Guide > Reference > User interface
|
|
information > Icons and buttons > Editor area marker bar</b></li>
|
|
<li>The editor area, see <b>Workbench User Guide > Reference > User interface
|
|
information > Views and editors > Editor area</b></li>
|
|
</ul>
|
|
<p>To create your C++ file:</p>
|
|
<ol>
|
|
<li>In the <b>C++ Projects</b> view, right-click the <b>HelloWorld</b> project
|
|
folder, and select <b>New > File</b>.</li>
|
|
<li>In the <b>File name</b> box, type <b>main.cpp</b>.</li>
|
|
<li>Click <b>Finish</b>.</li>
|
|
<li>Type the code below in the editor. Lines are indented with tab
|
|
characters, not with spaces.</li>
|
|
|
|
<blockquote>
|
|
<p>#include <iostream><br>
|
|
using namespace std;<br>
|
|
<br>
|
|
int main () {<br>
|
|
|
|
// Say Hello five times<br>
|
|
|
|
for (int index = 0; index < 5; ++index) <br>
|
|
|
|
cout << "HelloWorld!" << endl;<br>
|
|
<br>
|
|
|
|
char input = 'i';<br>
|
|
<br>
|
|
|
|
cout << "To exit, press 'm'" << endl;<br>
|
|
<br>
|
|
|
|
while(input != 'm') {<br>
|
|
|
|
cin >> input;<br>
|
|
|
|
cout << "You just entered " << input <br>
|
|
<< " you need to enter m to exit." << endl;<br>
|
|
|
|
}<br>
|
|
<br>
|
|
|
|
exit(0);<br>
|
|
}</p>
|
|
</blockquote>
|
|
<li>Click <b>File >
|
|
Save</b>.</li>
|
|
</ol>
|
|
|
|
<p>Your new .cpp file is displayed in the C/C++ Projects
|
|
view and in the Navigator view. Your project now contains main.cpp. Before you
|
|
can build your HelloWorld project, you must next create a makefile.</p>
