有10个学生，每个学生的数据包括学号、姓名、3门课程的成绩。从键盘输入10个学生的数据 要求输出 3 门课程的总平均成绩，以及最高分的学生的学号、姓名、3门课程成绩、平均分数。(定义结构体)

以下是C++代码：

#include <iostream>
#include <string>
using namespace std;

struct Student {
int id;
string name;
double score[3];
double avgScore;
};

int main() {
const int numStudents = 10;
Student students[numStudents];

// 从键盘输入学生数据
for (int i = 0; i < numStudents; i++) {
cout << "输入第" << i+1 << "个学生的学号、姓名、3门课程的成绩：" << endl;
cin >> students[i].id >> students[i].name;
double sumScore = 0;
for (int j = 0; j < 3; j++) {
cin >> students[i].score[j];
sumScore += students[i].score[j];
}
students[i].avgScore = sumScore / 3.0;
}

// 计算平均成绩和最高分的学生
double sumScores[3] = {0, 0, 0};
double maxScore = 0;
int maxScoreIndex = 0;
for (int i = 0; i < numStudents; i++) {
sumScores[0] += students[i].score[0];
sumScores[1] += students[i].score[1];
sumScores[2] += students[i].score[2];
if (students[i].avgScore > maxScore) {
maxScore = students[i].avgScore;
maxScoreIndex = i;
}
}
double avgScores[3] = {sumScores[0] / numStudents, sumScores[1] / numStudents, sumScores[2] / numStudents};

// 输出结果
cout << "3门课程的总平均成绩为：" << avgScores[0] << " " << avgScores[1] << " " << avgScores[2] << endl;
cout << "最高分的学生信息：" << endl;
cout << "学号：" << students[maxScoreIndex].id << endl;
cout << "姓名：" << students[maxScoreIndex].name << endl;
cout << "成绩：" << students[maxScoreIndex].score[0] << " " << students[maxScoreIndex].score[1] << " " << students[maxScoreIndex].score[2] << endl;
cout << "平均分数：" << students[maxScoreIndex].avgScore << endl;

return 0;
}
