类模板 

std::list
template < class T, class Alloc = allocator > class list;
list
list是顺序容器，允许在序列中的任何位置进行固定时间的插入和删除操作，并允许双向迭代。
list容器被实现为双链表；双链表可以将它们包含的每个元素存储在不同的、不相关的存储位置。顺序在内部通过与前面元素的链接和后面元素的链接的每个元素的关联来保持。
它们与forward_list非常相似：主要的区别是forward_list对象是单链表，因此它们只能向前迭代，以换取更小和更高效。
与其他基本标准顺序容器（array、vector和deque）相比，list在插入、提取元素和移动元素到容器内已经获得iterator的任何位置方面通常表现得更好，因此在大量使用这些元素的算法（如排序算法）中也表现得更好。
与其他顺序容器相比，lists和forward_list的主要缺点是它们不能通过位置直接访问元素；例如，要访问list中的第6个元素，必须从已知位置（如开始或结束）迭代到该位置，这需要以这些位置之间的距离为线性的时间。它们还消耗一些额外的内存来保持与每个元素相关联的链接信息（这可能是包含小型元素的大型的list的一个重要因素）。

容器的属性
按顺序排列的 
顺序容器中的元素按照严格的线性顺序排列。各个元素通过它们在该序列中的位置进行访问。
双向链接链表
每个元素都保存关于如何定位下一个和上一个元素的信息，允许在特定元素之前或之后（甚至是整个范围）进行固定时间的插入和删除操作，但不能直接随机访问。
能够感知的allocator
容器使用allocator对象动态处理其存储需求。

模板形参 
T
元素的类型。
别名为成员类型list::value_type。
Alloc
用于定义存储分配模型的allocator对象的类型。默认情况下，使用allocator类模板，它定义了最简单的内存分配模型，并且与值无关。
别名为成员类型list::allocator_type。
