一道练习题。

（涉及list，sort）

题目（大致）

将Person自定义类型进行排序（Person中属性有姓名、年龄、身高），按照年龄进行升序，如果年龄相同则按照身高进行降序。

运行代码

#include <iostream>
#include <string>
#include <list>using namespace std;class Person
{
public:string m_Name;int m_Age;int m_Height;public:Person(string name, int age, int height){this->m_Name = name;this->m_Age = age;this->m_Height = height;}
};bool comparePerson(Person &p1, Person &p2)
{if (p1.m_Age == p2.m_Age){return p1.m_Height > p2.m_Height;}else{return p1.m_Age < p2.m_Age;}
}void test01()
{list<Person> l;Person p1("p1", 23, 166);Person p2("p2", 23, 156);Person p3("p3", 23, 178);Person p4("p4", 33, 172);Person p5("p5", 43, 190);Person p6("p6", 45, 175);l.push_back(p1);l.push_back(p2);l.push_back(p3);l.push_back(p4);l.push_back(p5);l.push_back(p6);cout << "排序前：" << endl;for (list<Person>::iterator it = l.begin(); it != l.end(); it++){cout << it->m_Name << " " << it->m_Age << " " << it->m_Height << endl;}l.sort(comparePerson);cout << "排序后：" << endl;for (list<Person>::iterator it = l.begin(); it != l.end(); it++){cout << it->m_Name << " " << it->m_Age << " " << it->m_Height << endl;}
}int main()
{test01();return 0;
}

输出结果
