这题这么错的啊？哪位大佬帮个忙？

#include <bits/stdc++.h>

using namespace std;
const int N = 1010;

struct node {
    int id;
    double sc1, sc2;
    int score;
    double final_score;
} a[N];

int main() {
    int n;
    cin >> n;
    for (int i = 0; i < n; i++) {
        cin >> a[i].id >> a[i].sc1 >> a[i].sc2;
        a[i].score = a[i].sc1 + a[i].sc2;
        a[i].final_score = a[i].sc1 * 0.7 + a[i].sc2 * 0.3;
    }
    for (int i = 0; i < n; i++)
        if (a[i].score > 140 && a[i].final_score >= 80) 
            cout << "Excellent" << endl;
        else cout << "Not excellent" << endl;

    return 0;
}
