栈stack

使用：

队列queue

双向循环链表list

list构造函数

list 赋值和交换

list 大小操作

list 插入和删除

list 数据存取

list 反转和排序

排序算法sort降序操作

排序案例

#include<iostream>
using namespace std;
#include<list>class Person {
private:string name;int age;int hight;public:Person(string n, int a, int h) {this->name = n;this->age = a;this->hight = h;}void show() const{cout << "姓名：" << this->name << " " << "年龄：" << this->age << " " << "身高：" << this->hight << endl;}string getName() const {return name;}int getAge() const {return age;}int getHight() const {return hight;}};bool comparePerson(const Person& p1, const Person& p2) {if (p1.getAge() < p2.getAge())				//年龄升序return true;else if (p1.getAge() == p2.getAge()) {	if (p1.getHight() > p2.getHight())		//身高降序return true;}return false;
}void printPerson(const list<Person> &L) {for (list<Person>::const_iterator it = L.begin(); it != L.end(); it++) {it->show();}
}int main() {list<Person> persons;Person p1("张三", 20, 160);Person p2("李四", 18, 180);Person p3("王五", 8, 180);Person p4("赵六", 18, 150);//插入数据persons.push_back(p1);persons.push_back(p2);persons.push_back(p3);persons.push_back(p4);cout << "排序前" << endl;printPerson(persons);persons.sort(comparePerson);cout << "排序后" << endl;printPerson(persons);}

集合set（排序树）

set构造和赋值

set大小和交换

set插入和删除

set查找和统计

set和multiset区别

pair对组

set容器排序

set存放内置数据类型

set存放自定义数据类型

字典map

map构造和赋值

map大小和交换

map插入和删除

set查找和统计

map和multimap区别

同set

map容器排序
