某人需要对某班学生成绩进行处理，生成班级成绩单。假设班级人数为N（为了方便调试程序，N取5），学生的学号、姓名均不超过10个字符，输入每个学生的学号、姓名、4科成绩（例如：英语、数学、体育、计算机），计算每个学生的总分、平均分，然后按照总分由高到低排名，输出原始的成绩单和排名后的成绩单。利用一维、二维数组 c语言
#include <stdio.h>

#define NUM 5 //5个学生，方便修改
typedef struct _Student
{
char id[11]; // 学号
char name[11]; // 姓名
float score[4]; // 4科成绩
float total; // 总分
float avg; // 平均分
}Student;
int main()
{
Student stu[NUM]; // 学生信息数组
int i, j;
// 输入学生信息和成绩
for (i = 0; i < NUM; i++)
{
printf("请输入第%d个学生的学号:",i+1);
scanf("%s",stu[i].id);
printf("请输入第%d个学生的姓名:",i+1);
scanf("%s",stu[i].name);
stu[i].total = 0;

scanf("%f", &stu[i].score[j]);
stu[i].total += stu[i].score[j];
}
stu[i].avg = stu[i].total/4;

printf("原始成绩单：\n");
