СРОЧНО! Помогите с задачей.

using namespace std;

unsigned time;

}
friend istream& operator>>(istream& inp, Subscriber& s) {
return inp >> s.name >> s.code >> s.time;
}
friend ostream& operator<<(ostream& out, const Subscriber& s) {

class Listing {

}

}
void show()const {

for (const auto& x : box) {
cout << setw(3) << ++n << ". " << x << '\n';
}
}
private:

};

for (auto i = 0U; i < n; ++i) {
Subscriber ss;
cin >> ss;
sheet.add(ss);
}
system("cls");
sheet.order();
sheet.show();
}

Input:

Quantity: 34
Insert list of records:
Eric US 8
Butters UA 11
Kyle UK 7
Stan AU 24
Butters AU 36
Eric US 12
Stan UA 18
Eric UK 8
Butters UA 14
Stan AU 5
Stan UA 26
Butters AU 17
Eric US 27
Randy US 6
Stan UA 15
Butters UA 17
Eric UK 36
Stan UA 42
Randy US 9
Kyle UK 14
Stan AU 12
Butters UA 23
Eric US 32
Randy US 13
Stan UA 34
Butters AU 12
Eric UK 11
Butters UA 6
Butters AU 23
Stan AU 20
Randy US 18
Kyle UK 9
Butters UA 27
Stan UA 9

Output:

1. Butters UA 98
2. Butters AU 88
3. Eric US 79
4. Eric UK 55
5. Kyle UK 30
6. Randy US 46
7. Stan AU 61
8. Stan UA 144

Это на фриланс. Тут писанины не оберешься...
