1. std::list 的基本概念 std::list 是一个双向链表(doubly linked list)容器,包含在 <list> 头文件中。它支持在序列的任意位置进行高效的插入和删除操作。 2. std::list 底层使用的数据结构 std::list 的底层数据结构是双向链表。每个节点包含数据元素以及指向前一个节点和后一个节点的指针。这种结构...

【摘要】 @TOC 前言C++标准模板库(STL)提供了多种容器类来处理不同的数据结构,其中std::forward_list是用于实现单向链表(Singly Linked List)的容器。与其他容器如std::list、std::vector相比,std::forward_list更为轻量,专为需要快速插入和删除操作、以及内存效率的应用场景而设计。本篇文章将详细介绍std::forwa...
什么是list list即环状双向链表,即Circular Double Linked List。 list的继承层次 list定义在stl_list.h 中,它的继承关系如下所示: list-> _List_base [_List_impl -->_Node_alloc_type] list继承自_LIst_base,而_List_base内含了一个_List_impl类,而_List_impl继承自_Node_alloc_type。 _Node_alloc_ty...
Doubly-linked list: Each element keeps information on how to locate the next and the previous elements, allowing constant time insert and erase operations before or after a specific element (even of entire ranges), but no direct random access. ...
usinglist=std::list<T,std::pmr::polymorphic_allocator<T>>; } (2)(since C++17) std::listis a container that supports constant time insertion and removal of elements from anywhere in the container. Fast random access is not supported. It is usually implemented as a doubly-linked list. Com...

While trying to understand linked lists I've come across this or similar ways to construct linked lists: typedefstructnode{intdata; node *next; }node;node*init(inta[],intn){ node *head, *p;for(inti=0; i<n; ++i){ node *nd =newnode(); ...
