案例描述: 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: 按照年龄进行升序,如果年龄相同按照身高进行降序
- #include<iostream>
- using namespace std;
- #include<string>
- #include<list>
-
- //list容器 排序案例 对于自己定义数据类型 做排序
-
- //按照年龄进行升序,如果年龄相同按照身高进行降序
-
- 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;//姓名
- int m_Age; //年龄
- int m_Height; //身高
- };
-
- //指定排序规则
- bool comparePerson(Person& p1, Person& p2)
- {
- //按照年龄 升序
- if (p1.m_Age == p2.m_Age)
- {
- //年龄相同 按照身高降序
- return p1.m_Height > p2.m_Height;
- }
- else
- {
- return p1.m_Age < p2.m_Age;
- }
-
- }
-
- void test01()
- {
- list<Person>L;//创建容器
-
- //准备数据
- Person p1("李四", 35, 175);
- Person p2("老王", 45, 180);
- Person p3("张三", 40, 170);
- Person p4("老李", 25, 160);
- Person p5("老五", 35, 160);
- Person p6("狗蛋", 35, 200);
-
- //插入数据
- 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;
- }
-
- L.sort(comparePerson);//对于自定义排序我们需要指定他的规则
- 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()
- {
-
-
- system("pause");
-
- return 0;
- }
仅个人看视频笔记与理解,如有误可指出谢谢
