第一个测试点紫RE是怎么回事？？？？？？？

#include<iostream>
using namespace std;
#include<string>
struct student{
	string name[5];
	int age[5];
	int score[5];	
};
int main(){
	int a;
	cin>>a;
	student s1;
	for(int i=1;i<=a;i++){
		cin>>s1.name[i]>>s1.age[i]>>s1.score[i];
	}
	for(int i=1;i<=a;i++){
		s1.age[i]++;
		s1.score[i]*=1.2;
		if(s1.score[i]>600){
			s1.score[i]=600;
		}
	} 
	for(int i=1;i<=a;i++){
		cout<<s1.name[i]<<" "<<s1.age[i]<<" "<<s1.score[i]<<endl;
	}
	return 0;
}
