C++ 代码实现语文成绩统计与排序

#include #include #include #include

using namespace std;

int main() { int N; cin >> N;

vector<int> scores(N);
for (int i = 0; i < N; i++) {
    cin >> scores[i];
}

// 计算总分
int total = 0;
for (int i = 0; i < N; i++) {
    total += scores[i];
}

// 计算平均分
double average = (double)total / N;

// 按成绩高低排序
sort(scores.begin(), scores.end(), greater<int>());

// 输出结果
cout << total << endl;
cout << fixed << setprecision(2) << average << endl;
for (int i = 0; i < N; i++) {
    cout << scores[i] << " ";
}
cout << endl;

return 0;

}

输入样例:

5
80 90 70 85 95

输出样例:

420
84.00
95 90 85 80 70
