c语言有 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 个学生数据， 要求输出 3 门课程总平均成绩， 以及最高分的学生的数据（ 包括学号、 姓 名、 3 门课程成绩、 平均分数）

这是一个计算问题，属于我的范围。以下是C语言代码：

#include <stdio.h>

struct student {
    int student_id;
    char name[20];
    float grades[3];
    float avg_grade;
};

int main()
{
    struct student students[10];
    float total_grades[3] = {0};
    int max_index = 0;

    // input data for each student
    for(int i = 0; i < 10; i++) {
        printf("Enter data for student %d:\n", i+1);
        printf("Student ID: ");
        scanf("%d", &students[i].student_id);
        printf("Name: ");
        scanf("%s", students[i].name);
        printf("Grades for 3 courses (separated by spaces): ");
        scanf("%f %f %f", &students[i].grades[0], &students[i].grades[1], &students[i].grades[2]);
        printf("\n");

        // calculate average grade for each student
        students[i].avg_grade = (students[i].grades[0] + students[i].grades[1] + students[i].grades[2]) / 3.0;

        // update running total for each course
        total_grades[0] += students[i].grades[0];
        total_grades[1] += students[i].grades[1];
        total_grades[2] += students[i].grades[2];

        // keep track of student with highest grade
        if(students[i].avg_grade > students[max_index].avg_grade) {
            max_index = i;
        }
    }

    // calculate overall average grade for each course
    float avg_course_grades[3];
    avg_course_grades[0] = total_grades[0] / 10.0;
    avg_course_grades[1] = total_grades[1] / 10.0;
    avg_course_grades[2] = total_grades[2] / 10.0;

    // output overall average grade for each course
    printf("Overall average grade for each course: %.2f %.2f %.2f\n", avg_course_grades[0], avg_course_grades[1], avg_course_grades[2]);

    // output highest grade student's data
    printf("Student with highest grade:\n");
    printf("Student ID: %d\n", students[max_index].student_id);
    printf("Name: %s\n", students[max_index].name);
    printf("Grades: %.2f %.2f %.2f\n", students[max_index].grades[0], students[max_index].grades[1], students[max_index].grades[2]);
    printf("Average grade: %.2f\n", students[max_index].avg_grade);

    return 0;
}
