@Katie_Rabbit

给你改了一下

#include <bits/stdc++.h>
using namespace std;

struct stu{
    string name;
    int year,month,day,rk;
}s[1001];

bool cmp(stu x,stu y)//cmp函数最好用bool 返回
{
    if(x.year == y.year){
        if(x.month == y.month){
            if(x.day == y.day)return x.rk>y.rk;
            return x.day<y.day;
        }
        return x.month<y.month; 
    } 
    return x.year<y.year;
}

int main()
{
    int n;
    cin >> n;
    for(int i=1;i<=n;i++)
    {
        cin >> s[i].name >> s[i].year >> s[i].month >> s[i].day;
        s[i].rk=i;
    }
    sort(s+1,s+1+n,cmp);    
    for(int i=1;i<=n;i++)
        cout << s[i].name << endl;

    return 0;
}

@Katie_Rabbit

你这代码让我有一种我刚学C++时的感觉。
