1.queue容器基本概念

2.queue常用接口

#include <iostream>
using namespace std;//队列queue
#include<queue>//创建Person类
class Person
{
public:Person(string name, int age){this->m_Name = name;this->m_Age = age;}string m_Name; //姓名int m_Age; //年龄
};void test01()
{//创建西游记人物对象Person p1("唐僧", 30);Person p2("孙悟空", 1000);Person p3("猪八戒", 800);Person p4("沙僧", 600);//创建队列queuequeue<Person>q;//入队q.push(p1);q.push(p2);q.push(p3);q.push(p4);cout << "队列queue大小为：" << q.size() << endl;//判断queue有没有空，没空往下执行while (!q.empty()){//输出队头队尾cout << "队头元素姓名为：" << q.front().m_Name << "\t\t年龄为：" << q.front().m_Age << endl;cout << "队尾元素姓名为：" << q.back().m_Name << "\t\t年龄为：" << q.back().m_Age << endl;//出队q.pop();}cout << "队列queue大小为：" << q.size() << endl;
}int main() 
{ test01();//**************************************system("pause");return 0;
