哪位大佬能帮我康康

#include<iostream>
using namespace std;
struct student{
    int yw,sx,yy;
    string name;
}a[101];
int main(){
    int n,maxxyw=0,maxxsx=0,maxxyy=0,maxx=0;
    string maxxname;
    cin>>n;
    for(int i=1;i<=n;i++){
        cin>>a[i].name>>a[i].yw>>a[i].sx>>a[i].yy;
        if(a[i].yw+a[i].sx+a[i].yy>maxx){
            maxx=a[i].yw+a[i].sx+a[i].yy;
            maxxyw=a[i].yw;
            maxxsx=a[i].sx;
            maxxyy=a[i].yy;
            maxxname=a[i].name;
        }
    }
    cout<<maxxname<<" "<<maxxyw<<" "<<maxxsx<<" "<<maxxyy;
  return 0;
}

我真的觉得没问题了
