代码如下：

#include <iostream>
using namespace std;
int n = 0;
struct Students{
	int chinese = 0;
	int maths = 0;
	int english = 0;
	int all;
	int id = 0;
};
int main(){
	cin>>n;
	Students stu[n];
	for(int i = 0;i < n;i++){
		stu[i].id = i + 1;
		cin>>stu[i].chinese>>stu[i].maths>>stu[i].english;
		stu[i].all = stu[i].chinese+stu[i].english+stu[i].maths;
	}
	for(int i = 0;i < n;i++){
		for(int j = 0,m = 0;j < i;j++){
			if(stu[j].all < stu[i].all){
				m = stu[i].all;
				stu[i].all = stu[j].all;
				stu[j].all = m;
				m = stu[i].id;
				stu[i].id = stu[j].id;
				stu[j].id = m;
			}
		}
	}
	for(int i = 0;i < 5;i++){
		cout<<stu[i].id<<" "<<stu[i].all<<endl;
	}
	return 0;
}
