这段代码哪里错了啊?

#include<stdio.h>
#include<malloc.h>
#include<assert.h>
#define N 5
struct Student
{
int num;
char name[20];
double score[3];
};

Student* Input(Student* Stu, int len)
{
assert(Stu != NULL);
printf("请输入学生信息,编号 姓名 课程1成绩,课程2成绩,课程3成绩\n");
for (int i = 0; i < len; i++)
{
scanf_s("%d %s", &Stu[i].num, &Stu[i].name, 20);
for (int j = 0; j < 3; j++)
{
scanf_s("%lf", &Stu[i].score[j]);
}

}
return Stu;

}
void Print(Student* Stu, int len)
{
int count = 0;
double tmp = 0;
double max = 0;
double tmp1 = 0;
double tmp2 = 0;
double tmp3 = 0;
double* arr = (double*)malloc(sizeof(double) * len);
double* brr = (double*)malloc(sizeof(double) * len);
double* crr = (double*)malloc(sizeof(double) * len);
double* drr = (double*)malloc(sizeof(double) * len);
for (int i = 0; i < len; i++)
{
tmp1 += Stu[i].score[0];
tmp2 += Stu[i].score[1];
tmp3 += Stu[i].score[2];
for (int j = 0; j < 3; j++)
{
tmp += Stu[i].score[j];
}
arr[i] = tmp;
tmp = 0;
}
for (int i = 0; i < len; i++)
{
if (max < arr[i])
{
max = arr[i];
count = i;
}
}
tmp1 = tmp1 / len;
tmp2 = tmp2 / len;
tmp3 = tmp3 / len;
printf("课程1平均成绩:%f 课程2平均成绩: %f 课程3平均成绩: %f\n", tmp1, tmp2, tmp3);
printf("最高分学生数据为: %d %s ", Stu[count].num, Stu[count].name);
for (int i = 0; i < 3; i++)
{
printf("%f ", Stu[count].score[i]);
}
printf("%f\n", max/3);

//释放动态内存
free(arr);
free(brr);
free(crr);
free(drr);
}
int main()
{

Student Stu1[N] = { 0 };
Input(Stu1, (sizeof(Stu1) / sizeof(Stu1[0])));
Print(Stu1, (sizeof(Stu1) / sizeof(Stu1[0])));


return 0;

}
