    <p>There are some things unclear with your code and explanation. I will try to clarify and explain as well as possible.</p> <p>First of all, the program works fine when I ran it. There were some aesthetic problems, but we will ignore that for now.</p> <p>So, you have grasped the basics of I/O. When you use <strong>cout</strong>, it outputs something, and when you use <strong>cin</strong>, it is an input operator. Therefore, you must <strong>input</strong> something for it to work, as shown in example below:</p> <pre><code>//Code int x; cout &lt;&lt;"Enter an integer: "&lt;&lt;; cin &gt;&gt; xxx; </code></pre> <p>What should appear on console:</p> <pre><code>&gt;Enter an integer: _ </code></pre> <p>(Underscore is cursor). You then should enter an integer</p> <pre><code>&gt;Enter an integer: 231 </code></pre> <p>Then, upon pressing enter, the integer you entered, 231, is stored in XXX. Here I have to pause and ask, what is the reason for the "2011" in your code:</p> <pre><code>cout &lt;&lt; "Enter an integer: 2011 "; </code></pre> <p>If you think that's the input, it isn't. You have to manually write something in the console window after you run it. If it is something else, it is distracting and...well...useless.</p> <p>The same principles apply to the <strong>string</strong> component. If you need me to clarify, just let me know. </p> <p>Also, you really should use spaces to clear up your outputs. Your output text is displayed according to:</p> <pre><code>cout &lt;&lt; yyy &lt;&lt; "entered" &lt;&lt;&lt; xxx; </code></pre> <p>Instead, you should use:</p> <pre><code>cout &lt;&lt; yyy &lt;&lt; " entered " &lt;&lt; xxx; </code></pre> <p>This gives a neater output that you can read, i.e.</p> <pre><code>&gt;Johnentered231 </code></pre> <p>versus</p> <pre><code>&gt;John entered 231 </code></pre> <p><strong>Based on your comment</strong></p> <p>Here are some links to get you started:</p> <p><em>Language:</em> <a href="http://www.cplusplus.com/doc/tutorial/" rel="nofollow">C++ Tutorial (follow them sequentially!)</a></p> <p><em>Compiler</em>: <a href="http://www.bloodshed.net/devcpp.html" rel="nofollow">BloodShed Dev</a> <a href="http://msdn.microsoft.com/en-us/vstudio/aa718325.aspx" rel="nofollow">Visual Studio (C++ and more)</a></p>

    1. COOh, I see. That sounds logical. However, I'm currently using this site: http://www.compileonline.com/compile_cpp_online.php. And here I'm not getting the >Enter an integer:_ , am I doing something wrong or is that true for you too?

    2. COOkay, I seriously suggest using a compiler rather than online compiler. There are several, including Visual C++ Express (free), Bloodshed Dev, and Borland. If you are serious about learning and are beginning, I applaud it, but it is better to do it with proper tools. The online compiler does not seem to accept inputs.

    3. COYes, I agree 100%, but sadly I'm having problems with my C++ express (as you can see in my previous question). But since that's not really part of this question, +1 for this awesome answer. If you could only clarify why it says entered0 (not really important, just for interest), I'll accept your answer.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
