90分求助！！ 第一个点RE，vscode显示结构体有出现问题

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

struct student
{
    string name;
    int score;
    int chinese;
    int maths;
    int English;
}sst[1005];
bool cmp(student a,student b)
{
    return a.score<=b.score;
}

int main()
{
    cin>>n;
    for (int i = 0; i < n; i++)
    {
        cin>>sst[i].name>>sst[i].chinese>>sst[i].maths>>sst[i].English;
        sst[i].score = sst[i].chinese+sst[i].maths+sst[i].English;
    }
    sort(sst,sst+n,cmp);
    cout<<sst[n-1].name<<" "<<sst[n-1].chinese<<" "<<sst[n-1].maths<<" "<<sst[n-1].English;
    system("pause");
    return 0;
