C语言实现录入学生信息并按分数排序输出

#include <stdio.h>

typedef struct student {
    char name[20];
    int score;
}stu;

static void add_stu_info(stu student[], int n);
static void show_stu_info(stu student[], int n);

#include "student.h"

void bubble_sort(stu student[], int n) {
    stu temp;
    for (int i = 0; i < n - 1; i++) {
        for (int j = 0; j < n - i - 1; j++) {
            if (student[j].score < student[j + 1].score) {
                temp = student[j];
                student[j] = student[j + 1];
                student[j + 1] = temp;
            }
        }

    }
}

#include "student.h"

#define NUM 5
extern void bubble_sort(stu student[], int n);

int main() {
    stu students[NUM];
    add_stu_info(students, NUM);
    bubble_sort(students, NUM);
    show_stu_info(students, NUM);
    return 0;
}

static void add_stu_info(stu student[], int n) {
    for (int i = 0; i < n; i++) {
        printf("请输入学生姓名:\n");
        scanf_s("%s", &student[i].name, 20);
        printf("请输入学生得分:\n");
        scanf_s("%d", &student[i].score);
    }
}

    for (int i = 0; i < n; i++) {
        printf("姓名:%s,分数:%d\n", student[i].name, student[i].score);
