<p>Once a file has been opened for writing a string can be written to the
file using the <code>fputs</code> function. The following example shows
how to write the string ‘<samp><span class="samp">Free Software is needed for Free Science</span></samp>’
to the file ‘<samp><span class="samp">free.txt</span></samp>’.
<pre class="example"> filename = "free.txt";
fid = fopen (filename, "w");
fputs (fid, "Free Software is needed for Free Science");
fclose (fid);
</pre>

<p>A function much similar to <code>fputs</code> is available for writing data
to the screen. The <code>puts</code> function works just like <code>fputs</code>
except it doesn't take a file pointer as its input.
