错哪里了啊，求大佬帮帮

#include<bits/stdc++.h>
using namespace std;
int n,allsum;
struct chengji{
	string name;
	int num1,num2,num3,sum;
	char gb,xb;
}a[114514];
int maxn=0;
string maxname;
int main(){
	cin>>n;
	for(int i=1;i<=n;i++){
		cin>>a[i].name>>a[i].num1>>a[i].num2>>a[i].gb>>a[i].xb>>a[i].num3;
		if(a[i].num1>80 && a[i].num3>=1) a[i].sum+=8000;

		}
		allsum+=a[i].sum;
	}
	cout<<maxname<<endl<<maxn<<endl<<allsum;
	
	return 0;
