用struct（C语言）或class（C++语言）实现以下程序： 定义数据结构（struct或class）存储：至少10人的老师姓名（字符串），各个老师的课程名称（字符串数组，每个老师至少两门课程），各个老师的各门课程评教成绩：整数（百分值：0-100）数组，成绩的顺序和课程名称顺序对应 计算年终奖：年终奖=课程评教成绩均值*10-600 输入老师姓名（scanf），查询某名老师的所有评教成绩和今年的年终奖，警告那些年终奖为负数的老师

以下是基于C++语言的实现，使用class定义数据结构：

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

class Teacher {
public:
    string name; //老师姓名
    string courses[2]; //老师的两门课程
    int scores[2]; //老师的两门课程评教成绩
    float bonus; //年终奖

    Teacher(string n, string c1, int s1, string c2, int s2) {
        name = n;
        courses[0] = c1;
        scores[0] = s1;
        courses[1] = c2;
        scores[1] = s2;
        bonus = calculateBonus();
    }

    float calculateBonus() {
        float meanScore = (scores[0] + scores[1]) / 2.0; //计算两门课程平均成绩
        float bonus = meanScore * 10 - 600; //计算年终奖
        if (bonus < 0) { //判断年终奖是否为负数
            cout << "Warning: " << name << "'s bonus is negative." << endl;
        }
        return bonus;
    }

    void printScores() {
        cout << name << "'s scores:" << endl;
        cout << courses[0] << ": " << scores[0] << endl;
        cout << courses[1] << ": " << scores[1] << endl;
    }
};

int main() {
    Teacher teachers[10] = {
        Teacher("teacher1", "course1", 80, "course2", 90),
        Teacher("teacher2", "course1", 85, "course2", 95),
        Teacher("teacher3", "course1", 90, "course2", 92),
        Teacher("teacher4", "course1", 78, "course2", 85),
        Teacher("teacher5", "course1", 92, "course2", 88),
        Teacher("teacher6", "course1", 87, "course2", 93),
        Teacher("teacher7", "course1", 91, "course2", 89),
        Teacher("teacher8", "course1", 83, "course2", 82),
        Teacher("teacher9", "course1", 79, "course2", 87),
        Teacher("teacher10", "course1", 88, "course2", 90)
    };

    string name;
    cout << "Enter teacher name: ";
    cin >> name;

    for (int i = 0; i < 10; i++) {
        if (teachers[i].name == name) {
            teachers[i].printScores();
            cout << "Bonus: " << teachers[i].bonus << endl;
            break;
        }
    }

    return 0;
}

在main函数中，我们定义了一个Teacher类型的数组，存储了10个老师的数据。然后，用户输入老师姓名，程序遍历数组，找到对应老师的数据，打印评教成绩和年终奖。如果年终奖为负数，会输出警告信息。
