    <p>First; indent your code correctly (on Linux you could use the <a href="http://www.gnu.org/software/indent/" rel="nofollow">GNU indent</a> utility, or <a href="http://astyle.sourceforge.net/" rel="nofollow">astyle</a>).</p> <p>Compile it with all warnings and debugging info (e.g. <code>gcc -Wall -g</code>). Learn how to use the debugger (<code>gdb</code>) to run it step by step.</p> <p>Then, your <code>scanf("%s", str);</code> is dangerous (should at least be <code>scanf("%99s", str);</code>, see <a href="http://man7.org/linux/man-pages/man3/scanf.3.html" rel="nofollow">scanf(3)</a>) ! You could get crashes or <a href="http://en.wikipedia.org/wiki/Undefined_behavior" rel="nofollow">undefined behavior</a> if the user enters a very long "word" of 200 characters (e.g. 200 times the digit <code>0</code>). Alos notice that <code>%s</code> reads up to a space or blank-like character. I believe it is good habit to zero a buffer before reading it. So replace your <code>scanf</code> with </p> <pre><code> memset (str, 0, sizeof(str)); fgets (str, sizeof(str), stdin); </code></pre> <p>At last, you are not flushing the <a href="http://en.wikipedia.org/wiki/Buffer_%28computer_science%29" rel="nofollow">buffered</a> <code>stdout</code> output (see <a href="http://man7.org/linux/man-pages/man3/stdio.3.html" rel="nofollow">stdio(3)</a>, <a href="http://man7.org/linux/man-pages/man3/setvbuf.3.html" rel="nofollow">setvbuf(3)</a>, <a href="http://man7.org/linux/man-pages/man3/fflush.3.html" rel="nofollow">fflush(3)</a>, etc...). Try perhaps</p> <pre><code>while(str[i]) printf("%d ",str[i++]); putchar('\n'); fflush(stdout); </code></pre> <p>The last call to <code>fflush</code> is useless here, but it is a good habit (or else end <em>every</em> <code>printf</code> format string with a newline <code>\n</code> since <em><code>stdout</code></em> is often but not always line-buffered!)</p>

    3. CONothing wrong, it's just that the default style it applies is nonsense, it requires quite a bunch of flags to get something readable out of it.

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.

SQuiL has stopped working due to an internal error.

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