全是WA,代码如下：

#include<bits/stdc++.h>
using namespace std;
struct fen{
	string name;
	int qi,ban;
	char gan,xi;
	int lun,jiang=0;
}a[105];
int f(fen x){
	int much=0;
	if(x.qi>80 && x.lun>=1){
		much+=8000;
	}else if(x.qi>85 && x.ban>80){
		much+=4000;
	}else if(x.qi>90){
		much+=2000;
	}else if(x.qi>85 && x.xi=='Y'){
		much+=1000;
	}else if(x.ban>80 && x.gan=='Y'){
		much+=850;
	}
	return much;
}
int main(){
	int n,sum=0,max=-1;
	string ming;
	cin>>n;
	for(int i=0;i<n;i++){
		cin>>a[i].name>>a[i].qi>>a[i].ban>>a[i].gan>>a[i].xi>>a[i].lun;
		a[i].jiang=f(a[i]);
	}
	for(int i=0;i<n;i++){
		sum+=a[i].jiang;
		if(a[i].jiang>max){
			max=a[i].jiang;
			ming=a[i].name;
		}
	}
	cout<<ming<<endl<<max<<endl<<sum;
	return 0;
}
求各位帮助。
