头文件就卷亖你们的代码

话不多说，上代码

#include <iostream>
#include <cstdio>
#include <vector>
#include <algorithm>
using namespace std;
class Person{
public:
    string sex;
    float height;
};
/*
不会用class的这样写
struct Person{
    string sex;
    float height;
};
*/
int main(){
    int n;
    cin>>n;
    Person a[n];
    vector<float> m,f;
    for(int i=0;i<n;i++){
        cin>>a[i].sex>>a[i].height;
        if(a[i].sex == "male")
            m.push_back(a[i].height);
        else if(a[i].sex == "female")
            f.push_back(a[i].height);
    }
    sort(m.begin(),m.end());
    sort(f.begin(),f.end(),greater<float>());
    for(int i=0;i<m.size();i++) printf("%.2f ",m[i]);
    for(int i=0;i<f.size();i++) printf("%.2f ",f[i]);
    return 0;
}
