struct里面需要初始值，不然ans是没有初始值的
修改后：
```
#include<bits/stdc++.h>
using namespace std;
struct student{
string name;
int Chinese = -1,math = -1,English = -1;
}a,ans;
int main(){
int n;
cin>>n;
for(int i=0;i<n;i++){
cin>>a.name>>a.Chinese>>a.math>>a.English;
if(a.Chinese+a.English+a.math>ans.Chinese+ans.English+ans.math){
ans=a;
}
}
cout<<ans.name<<" "<<ans.Chinese<<" "<<ans.math<<" "<<ans.English;
}
