    <pre><code>CCard card; </code></pre> <p>is the way to use the default constructor.</p> <p>But your teacher is wrong, in C++ we will use free functions to extend functionalities very frenquently.</p> <p>In your case, it is wise to use the constructor because it is meant this way, except if you have special needs you don't need to do a newCard: this will generate unnecessary copies.</p> <hr> <p>"new" is reserved for pointers, so you have to use something like this:</p> <pre><code> CCard * card = new CCard(); </code></pre> <p>And you have to explicitly <code>delete</code> them. But pointers should be used only when necessary, and if possible not 'raw' but smart. (see smart pointers like boost::shared_ptr)</p> <hr> <p><strong>FOR YOUR EDIT</strong></p> <p>You can give your CCard new values using:</p> <p>-) a method of CCard like:</p> <pre><code>card.newValues(); </code></pre> <p>The constructor could also call "newValues()" to avoid being redundant.</p> <p>-) a free function (or a member of another class) that takes a CCard as a reference parameter:</p> <pre><code> void newValues( CCard &amp; card ) { /* set new values */ }; newValues( card ); </code></pre> <p>-) Directly</p> <pre><code> card.set( /*values*/ ); </code></pre> <p>Maybe with a set of accessors (set/get) if it means something for you class.</p> <p>The question you have to ask yourself is whether you want to change your class internals with accessors, or you only want to change its value inside the class.</p> <p>-) If you really want to call the constructor again, you can make a copy:</p> <pre><code> CCard c; c = CCard(); </code></pre> <p>But it's just like creating a new CCard.</p>

    1. CO`std::auto_ptr` / `std::unique_ptr` are perhaps better to begin with than `shared_ptr`.

    2. COYes the problem for beginners is to explain std::auto_ptr should not be used inside containers

    3. COThanks for answering to my edit ^^ As I thought, it's only cumbersome. Oof, teachers.But thanks for clarifying that!

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.
