    <p>Assuming the fix mentioned by Abhijit, why transform the first into the second? Are you aware that the second behaves differently to the first, because of the addition of <code>sscanf</code>? If your intention was to shorten the first, the second seems quite bulky. Rather than adding <code>sscanf</code> to the situation, why not shorten the first by declaring a <code>struct employee *e = employee + employee_num;</code> and using that repetitively, instead of <code>employee[employee_num]</code>?</p> <p>One "best practise" regarding <code>fgets</code> is to check it's return value. What do you suppose <a href="http://pubs.opengroup.org/onlinepubs/007904975/functions/fgets.html" rel="nofollow"><code>fgets</code></a> might return, if it encounters <code>EOF</code>? What do you suppose <a href="http://pubs.opengroup.org/onlinepubs/007904975/functions/fgets.html" rel="nofollow"><code>fgets</code></a> would return if it's successful?</p> <p>One "best practise" regarding <code>scanf</code> is to check it's return value. In regards to the return value of <code>scanf</code>, I suggest reading <a href="http://pubs.opengroup.org/onlinepubs/007904975/functions/scanf.html" rel="nofollow">this <code>scanf</code> manual</a> carefully and answering the following questions:</p> <ol> <li><code>int x = scanf("%d", &amp;employee[employee_num].salary);</code> What do you suppose <code>x</code> will be if I enter <code>"fubar\n"</code> as input?</li> <li>Where do you suppose the <code>'f'</code> from <code>"fubar\n"</code> will go?</li> <li>If it's <code>ungetc</code>'d back onto <code>stdin</code>, what would your next employee's last name be?</li> <li><code>int x = scanf("%d", &amp;employee[employee_num].salary);</code> What do you suppose <code>x</code> will be if I run this code on Windows and press CTRL+Z to send <code>EOF</code> to <code>stdin</code>?</li> <li><code>int x = scanf("%d %d", &amp;y, &amp;z);</code> What would you expect <code>x</code> to be, presuming <code>scanf</code> successfully puts values into the two variables <code>y</code> and <code>z</code>?</li> </ol> <p>P.S. <code>EOF</code> can be sent through <code>stdin</code> in Windows by CTRL+Z, and in Linux and friends by CTRL+D, in addition to using pipes and redirection to redirect input from other programs and files.</p>

    1. COThank you! Working through those questions gave me a much better understanding of what is going on when using scanf(). Correct me if I am wrong, but then I could write the stdin to an array and read the int values back to a variable using sscanf() ?

    2. COYes, fgets and sscanf will work that way. Be aware that the %s format specifier tells sscanf to copy a *word* (eg. zero or more non-whitespace characters up to the first whitespace). What happens to the rest of your fgets'd line? This is one way your second post differs from your first.

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.
