<p>
The get() function is used with input streams, and either:
</p>
<ul>
<li class="level1"><div class="li"> reads a character and returns that value,</div>
</li>
<li class="level1"><div class="li"> reads a character and stores it as ch,</div>
</li>
<li class="level1"><div class="li"> reads characters into buffer until num - 1 characters have been read, or <acronym title="End of file">EOF</acronym>, or newline encountered, or the delim character encountered (delim is not read until next time),</div>
</li>
<li class="level1"><div class="li"> or reads characters into buffer until a newline, <acronym title="End of file">EOF</acronym>, or delim character is encountered (again, delim isn't read until the next get() ).</div>
</li>
</ul>
<p>
For example, the following code displays the contents of a file called
temp.txt, character by character:
</p>
<pre class="c code c++" style="font-family:monospace;"> <span class="kw4">char</span> ch<span class="sy0">;</span>
ifstream fin<span class="br0">(</span> <span class="st0">"temp.txt"</span> <span class="br0">)</span><span class="sy0">;</span>
<span class="kw1">while</span><span class="br0">(</span> fin.<span class="me1">get</span><span class="br0">(</span>ch<span class="br0">)</span> <span class="br0">)</span>
<a href="http://www.opengroup.org/onlinepubs/009695399/functions/cout.html"><span class="kw3">cout</span></a> <span class="sy0"><<</span> ch<span class="sy0">;</span>
