    <p>Since this is an assignment I don't want to just give away any answers, but here is stuff that should help.</p> <p>I read your assignment and I don't see the word dynamic used anywhere. This means you can just create the array of size 50 to start.</p> <pre><code>// non dynamic array allocation: assignments assign[50]; // dynamic allocation containers vector&lt;assignments&gt; assign; // array list list&lt;assignments&gt; assign; // linked list queue&lt;assignments&gt; assign; // queue list, useful with insertion sort </code></pre> <p>To parse the input data I recommend <a href="http://www.cplusplus.com/reference/istream/istream/getline/" rel="nofollow"><code>getline</code></a> with <a href="http://www.cplusplus.com/reference/cstring/strtok/?kw=strtok" rel="nofollow"><code>strtok</code></a> to break the line into the proper data.</p> <p>Example:</p> <pre><code>int linelength = 256; // don't forget the +1 for end of string terminator char *whitespaces = " \t" // \n and \0 will never be part of the token based on getline char line[256]; // or some other safe number length char *token; // no need to define size inputstream.getline(line, 256); token = strtok(line, whitespaces); // save token to correct location token = strtok(NULL, whitespaces); // save token to correct location token = strtok(NULL, whitespaces); // save token to correct location // ... </code></pre> <p>Just don't expect to use <code>line</code> after <code>strtok</code>s.</p> <p>As for your <code>ReadFile</code> function, I would give it the input stream and have it return one of the dynamic containers. I try to minimize how often I modify parameters.</p> <pre><code>vector&lt;assignment&gt; load(istream) { // stuff like the second block of code goes here return assign; } </code></pre> <p>Hope this helps.</p> <p>Thanks,</p> <ul> <li>Will</li> </ul>

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.
