案例描述:将Perspn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

代码示例

#include <iostream>
#include <string.h>
#include <iterator>
#include <vector>
#include <string>
#include <algorithm>
#include <deque>
#include <bitset>
#include <ctime>
#include <stack>
#include <queue>
#include <list>
using namespace std;class  person 
{

};bool  comparePerson(person &p1,person &p2)
{//按照年龄进行升序if (p1.age == p2.age){//如果年龄相同按照身高进行降序return p1.height > p2.height;}else{return p1.age < p2.age;}
}void print(list<person>& p)
{for (list<person>::iterator it = p.begin(); it != p.end(); it++){cout << "姓名: " << it->name << " 年龄: " << it->age << " 身高: " << it->height << endl;}
}
int main()
