C++实现

#include<iostream>
#include<vector>
#include<algorithm>using namespace std;struct student {char name[10];int one;  //第一科成绩int two; int three;int total; //总成绩bool flag;//是否挂科
};bool cmp(student a, student b) {都是3科，平均成绩越高总成绩就越高，所以只需比较总成绩return a.total > b.total;
}int main() {int N;//读入学生信息while (cin >> N) {vector<student> s;for (int i = 0; i < N; i++){student t;cin >> t.name >> t.one >> t.two >> t.three >> t.total;if (t.one < 60 || t.two < 60 || t.three < 60) {t.flag = false;//挂科则为false}else {t.flag = true;}s.push_back(t);}//如果挂科了for (int i = 0; i < s.size(); i++){if (!s[i].flag) {cout << "*[" << s[i].name << "]";cout << " " << s[i].one << " " << s[i].two << " " << s[i].three << endl;}}sort(s.begin(), s.end(), cmp);for (int i = 0; i < s.size(); i++){cout << s[i].name;cout << " " << s[i].one << " " << s[i].two << " " << s[i].three << endl;}}return 0;
