定义一个学生结构体Student(含学号、姓名、成绩)和一个函数sort(struct+Student+*p)，该函数使用选择排序法按成绩升序排序。在主函数中输入10个学生的学号、姓名和成绩，调用so

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

struct Student {
    char id[20];
    char name[20];
    float score;
};

void sort(struct Student *p, int n) {
    int i, j, min_index;
    struct Student temp;
    for (i = 0; i < n - 1; i++) {
        min_index = i;
        for (j = i + 1; j < n; j++) {
            if (p[j].score < p[min_index].score) {
                min_index = j;
            }
        }
        if (min_index != i) {
            temp = p[i];
            p[i] = p[min_index];
            p[min_index] = temp;
        }
    }
}

int main() {
    int n = 10;
    struct Student *students = (struct Student *)malloc(n * sizeof(struct Student));
    int i;
    for (i = 0; i < n; i++) {
        printf("请输入第%d个学生的学号、姓名和成绩：", i + 1);
        scanf("%s%s%f", students[i].id, students[i].name, &students[i].score);
    }
    sort(students, n);
    printf("排序后的学生信息为：\n");
    for (i = 0; i < n; i++) {
        printf("%s\t%s\t%.2f\n", students[i].id, students[i].name, students[i].score);
    }
    free(students);
    return 0;
}
