此页面尝试列出所有来自<i>标准库</i>，可用于命名空间 <i>std::literals::string_literals::</i> 的符号。符号以下列方式书写：</p>
|
|
<ul>
|
|
<li>函数名带 <i>()</i> 。</li>
|
|
<li>模板带 <i><></i> 。</li>

<p>这些运算符声明于命名空间 <code>std::literals::string_literals</code> ，其中 <code>literals</code> 与 <code>string_literals</code> 都是内联命名空间。对这些运算符的访问能用 <span class="t-c"><span class="mw-geshi cpp source-cpp"><span class="kw1">using</span> <span class="kw1">namespace</span> std<span class="sy4">::</span><span class="me2">literals</span></span></span> 、 <span class="t-c"><span class="mw-geshi cpp source-cpp"><span class="kw1">using</span> <span class="kw1">namespace</span> std<span class="sy4">::</span><span class="me2">string_literals</span></span></span> 及 <span class="t-c"><span class="mw-geshi cpp source-cpp"><span class="kw1">using</span> <span class="kw1">namespace</span> std<span class="sy4">::</span><span class="me2">literals</span><span class="sy4">::</span><span class="me2">string_literals</span></span></span> 获得。</p>

<p><span class="t-lc"><a href="cpp-chrono-duration.html">std::chrono::duration</a></span> 亦定义 <code>operator""s</code> 以表示字面量的秒，但它是算术字面量： <span class="t-c"><span class="mw-geshi cpp source-cpp">10.0s</span></span> 与 <span class="t-c"><span class="mw-geshi cpp source-cpp">10s</span></span> 是十秒，但 <span class="t-c"><span class="mw-geshi cpp source-cpp"><span class="st0">"10"</span>s</span></span> 是字符串。</p>
