很简单
嗯呢
啊
填空题
希望给一个答案

#include <iostream>
#include <cstring>
using namespace std;
class Student {
    char name[255];
    int course_num;
    float scores[10];
    float average_score;
public:
    Student(const char*name, int course_num);
    void CalculateAverageScore();
    friend ostream& operator << (ostream& out, const Student& s);
};

Student::Student(const char *name, int course_num) {
    strcpy(this->name, name);
    this->course_num = course_num;
    average_score = 0;
    
    cout << "请输入学生" << name << "的" << course_num << "门课的成绩：" << endl;
    for (int i = 0; i < course_num; i++) {
        cin >> scores[i];
    }
}
void Student::CalculateAverageScore() {
    float sum = 0;
    for (int i = 0; i < course_num; ++i) {
        sum += scores[i];
    }
    average_score = sum / course_num;
}

ostream& operator<< (ostream& out, const Student& stu) {
    cout << "学生 " << stu.name << " 的平均成绩为：" << stu.average_score << endl;
}

int main() {
    Student stu1("Tom", 3);
    stu1.CalculateAverageScore();
    cout << stu1;
    return 0;
}
