双向链表
结点的组成:一个是存储数据元素的**数据域**,另一个是存储下一个结点地址的**指针域**
构造函数
List 赋值和交换
容器大小操作
- 判断是否为空 --- empty
- 返回元素个数 --- size
- 重新指定个数 --- resize
插入和删除
* 尾插 --- push_back
* 尾删 --- pop_back
* 头插 --- push_front
* 头删 --- pop_front
* 插入 --- insert
* 删除 --- erase
* 移除 --- remove
* 清空 --- clear
数据存取
list <int > li;
li.front(); //第一个元素
li.back(); //最后一个元素
反转和排序
自定义排序案例,变量为类class
#include <list>
#include <string>
class Person {
public:Person(string name, int age , int height) {m_Name = name;m_Age = age;m_Height = height;}public:string m_Name; //姓名int m_Age; //年龄int m_Height; //身高
};bool ComparePerson(Person& p1, Person& p2) {//降序if (p1.m_Age == p2.m_Age) {return p1.m_Height > p2.m_Height;}else{//升序return p1.m_Age < p2.m_Age;}}void test01() {list<Person> L;Person p1("刘备", 35 , 175);Person p2("曹操", 45 , 180);Person p3("孙权", 40 , 170);Person p4("赵云", 25 , 190);Person p5("张飞", 35 , 160);Person p6("关羽", 35 , 200);L.push_back(p1);L.push_back(p2);L.push_back(p3);L.push_back(p4);L.push_back(p5);L.push_back(p6);for (list<Person>::iterator it = L.begin(); it != L.end(); it++) {cout << "姓名: " << it->m_Name << " 年龄: " << it->m_Age << " 身高: " << it->m_Height << endl;}cout << "---------------------------------" << endl;L.sort(ComparePerson); //排序for (list<Person>::iterator it = L.begin(); it != L.end(); it++) {cout << "姓名: " << it->m_Name << " 年龄: " << it->m_Age << " 身高: " << it->m_Height << endl;}
}int main() {test01();system("pause");return 0;
