D编程语言printf("Hello, world!")和writeln("Hello, world!")D编程语言有什么区别?
我注意到它writeln()最终会被自己打破,而printf()不是.这是唯一的区别吗?
D有任何表达方式和/或if语句吗?
if (1 > 2 or 3 < 5 and 1 == 1)
{
/* run code */
}

我如何根据我所处的路径向div添加一个CSS类,包括如果我有#在其中它不应该是mather?
<div class="popup">
<ul>
<li><a href="#vs">Example 1</a></li>
<li><a href="#bod">Example 2</a></li>
<li><a href="#ptf">Example 3</a></li>
</ul>
</div><!-- popup -->
