C语言创建一个名为student的结构体数组包含学号姓名分数数据类型自己定义从终端输入学生的信息并打印分数及格的学生信息输入3人即可。封装函数实现把其中第几个学生信息清零。

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

#define MAX_STUDENT 10

typedef struct {
    int id; // 学号
    char name[20]; // 姓名
    float score; // 分数
} Student;

Student student[MAX_STUDENT];
int count = 0;

void clearStudent(int index) {
    if (index < 0 || index >= count) {
        printf("Invalid index.\n");
        return;
    }
    student[index].id = 0;
    strcpy(student[index].name, "");
    student[index].score = 0;
}
