请写出代码

#include <iostream>
#include <vector>
#include <algorithm>
using namespace std;

struct Student {
    string id;
    string name;
    int math;
    int c;
};

bool cmp(Student a, Student b) {
    return a.c > b.c;
}

int main() {
    int n;
    cin >> n;
    vector<Student> students(n);
    for (int i = 0; i < n; i++) {
        cin >> students[i].id >> students[i].name >> students[i].math >> students[i].c;
    }
    sort(students.begin(), students.end(), cmp);
    for (int i = 0; i < n; i++) {
        cout << students[i].id << " " << students[i].name << " " << students[i].math << " " << students[i].c << endl;
    }
    return 0;
}
