好多次了，一直RE，好烦

#include<bits/stdc++.h>
using namespace std;
struct student {
    string name;
    int y, m, d;
}c[105];
bool cmp(student a, student b) {
    if (a.y != b.y)
        return a.y < b.y;
    if (a.m != b.m)
        return a.m < b.m;
    return a.d <= b.d;
}
int main() {
    int n;
    cin >> n;
    for (int i = 1; i <= n; i++) {
        cin >> c[i].name >> c[i].y >> c[i].m >> c[i].d;
    }sort(c + 1, c + n + 1, cmp);
    for (int i = n; i > 0; i++) {
        cout << c[i].name << endl;
    }return 0;
}

有问题吗...
