@hyh0174 string不能直接用scanf,printf

#include<cstdio>
#include<algorithm>
#include<string>
#include<iostream>
using namespace std;
struct stu
{
    string s;
    int y,m,d,o;
}sb[110];
bool cmp(stu a,stu b)
{
    if(a.y!=b.y)
        return a.y<b.y?true:false;
    else if(a.m!=b.m)
        return a.m<b.m?true:false;
    else if(a.d!=b.d)
        return a.d<b.d?true:false;
    else
        return a.o>b.o?true:false;
}
int main()
{
    int n;
    scanf("%d",&n);
    for(int i=0;i<n;i++)
    {
        cin>>sb[i].s;
        scanf("%d %d %d",&sb[i].y,&sb[i].m,&sb[i].d);
        sb[i].o=i+1;
    }
    stable_sort(sb,sb+n,cmp);
    for(int i=0;i<n;i++)
        cout<<sb[i].s<<endl;
    //or printf("%s\n",sb[i].s.c_str());
    return 0;
}

这样就A了
