    <p>Your code prints line numbers at the end of a line, right before printing the <code>'\n'</code>, because of the way you have written the loop. Otherwise, your code should work.</p> <p>If you want your code to print the line numbers at the beginning, you can do something like (untested):</p> <pre><code>int line_num_printed = 0; /* indicating if we printed a line number */ int line = 1; while ((c = fgetc(fp)) != EOF) { if (!line_num_printed) { printf("LINE %d: ", line); line_num_printed = 1; } putchar(c); if (c == '\n'){ line++; line_num_printed = 0; } } </code></pre> <p>If there is something else that "doesn't work", you should post complete code and tell us what doesn't work.</p> <p><em>Edit</em>: The proper way to check a character for a newline is to test against <code>'\n'</code>. If the character came from a file, you should also make sure you open the file in text mode, i.e., without a <code>b</code> in the second argument to <code>fopen()</code>.</p> <p>Also, you want <code>c</code> to be of type <code>int</code>, not <code>char</code>. This is because in C, <code>EOF</code> is a small negative number, and if <code>char</code> is unsigned, comparing it against a negative number convert the value of <code>EOF</code> to a positive value (equal to <code>EOF + UCHAR_MAX + 1</code> most likely). Therefore, you should <em>not</em> change <code>c</code> to <code>char</code> type. If you do, the comparison <code>c != EOF</code> might be false even when <code>fgetc()</code> returns <code>EOF</code>.</p>

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.
