<h2><a name="push_back" id="push_back">push_back</a></h2>
<div class="level2">
<p>
Syntax:
</p>
<pre class="c code c++" style="font-family:monospace;"> <span class="co2">#include <string></span>
<span class="kw4">void</span> push_back<span class="br0">(</span> Char c <span class="br0">)</span><span class="sy0">;</span></pre>
<p>
The push_back() function appends c to the end of the string.
For example, the following code adds 10 characters to a string:
</p>
<pre class="c code c++" style="font-family:monospace;"> <span class="kw4">string</span> the_string<span class="sy0">;</span>
<span class="kw1">for</span><span class="br0">(</span> <span class="kw4">int</span> i <span class="sy0">=</span> <span class="nu0">0</span><span class="sy0">;</span> i <span class="sy0"><</span> <span class="nu0">10</span><span class="sy0">;</span> i<span class="sy0">++</span> <span class="br0">)</span>
the_string.<span class="me1">push_back</span><span class="br0">(</span> i<span class="sy0">+</span><span class="st0">'a'</span> <span class="br0">)</span><span class="sy0">;</span></pre>
<p>
When displayed, the resulting string would look like this:
</p>
<pre class="c code c++" style="font-family:monospace;"> abcdefghij</pre>
<p>
