#include <iostream>

using namespace std;

int main()
{
    string max_name,max_id;
    string min_name,min_id;
    string current_name,current_id;
    int current_score;
    int max_score = -1,min_score = 101; 
    int n;//n个学生
    cin >> n;
    for(int i = 0; i < n; i++)
    {
        cin >> current_name >> current_id >> current_score;
        if(current_score > max_score) 
        {
            max_score = current_score;
            max_name = current_name;
            max_id = current_id;
        }
        if(current_score < min_score)
        {
            min_score = current_score;
            min_name = current_name;
            min_id = current_id;
        }        
    }
    cout << max_name << ' ' << max_id <<endl;
    cout << min_name << ' ' << min_id ;
    return 0;
}

第一次错在 min_score设置成了0，这样的话就没办法更新min_score了。。
