8.list排序案例

#include<iostream>
using namespace std;

#include<list>
#include<time.h>
//将Person自定义数据类型进行排序，Person中属性有姓名，年龄，身高
//排序规则：按照年龄进行排序，如果年龄相同按照身高进行降序排序

class Person
{
public:
    Person(string name,int age,int height)
    {
        this->m_Name = name;
        this->m_Age = age;
        this->m_Height = height;
    }
    string m_Name;
    int m_Age;
    int m_Height;
};

void PrintPerson(list<Person> l)
{
    for (list<Person>::iterator it = l.begin(); it != l.end(); it++)
    {
        cout << "姓名：" << it->m_Name << "\t"
            << "年龄：" << it->m_Age << "\t"
            << "身高：" << it->m_Height << endl;
    }
}
//指定排序规则
bool ComparePerson(Person& p1,Person& p2)
{
    if (p1.m_Age != p2.m_Age)
        return p1.m_Age < p2.m_Age;//按照年龄升序排序
    else
        return p1.m_Height > p2.m_Height;//年龄相同，按照身高升序排序
