You can solve it by building a structure.

#include <iostream>
using namespace std;

struct stu
{
	string z;
	int s;
	int k;
};

intmain()
{
	struct stu s[1001];
	int n;
	cin >> n;
	for(int i = 0; i < n; i++) {
		cin >> s[i].z;
		cin >> s[i].s;
		cin >> s[i].k;
	}
	
	int m;
	cin >> m;
	for(int i = 0; i < m; i++) {
		int num;
		cin >> num;
		for(int i = 0; i < n; i++) {
			if(s[i].s == num) {
				cout << s[i].z << " " << s[i].k << endl;
			}
		}
	}
	return 0;
}
