std::forward_listis a container that supports fast insertion and removal of elements from anywhere in the container. Fast random access is not supported. It is implemented as a singly-linked list. Compared tostd::listthis container provides more space efficient storage when bidirectional iteration ...

我们之前已经接触过STL中的部分容器,比如:vector、list、deque、forward_list(C++11)等,这些容器统称为序列式容器,因为其底层为线性序列的数据结构,里面存储的是元素本身。 而今天我们学习的map、set、multimap、multiset是关联式容器,关联式容器也是用来存储数据的,与序列式容器不同的是,其里面存储的...
