自定义数据类型-指向结构体数组的指针案例！

#include
#define N 3
 struct Student
 {
  long num;
  char name[20];
  float score[3];
  double aver;
 };
 int main ()
 {
  void input (struct Student stu[]);
  struct Student max(struct Student stu[]);
  void print(struct Student stu[]);
  struct Student stu[N],*p=stu;
  input(p);
  print(max(p));
  return 0;
 }

     void input(struct Student stu[])
  {
    int i;
    printf("请输入各学生的信息：学号、姓名、三门功课：\n");
     for(i=0;i     {
      scanf("%ld %s %f %f %f",&stu[i].num，&stu[i].name,&stu[i].score[0],&stu[i].score[1],&stu[i].score[2]);
      stu[i].aver=(stu[i].score[0]+stu[i].score[1]+stu[i].score[2])/3.0;
     }
     }

  struct Student max(struct Student stu[])
  {
   int m=0,i;
   for(i=0;i   {
    if(stu[i].aver>stu[m].aver)
     m=i;
    return stu[m];
   }
  }

  void print(struct Student stu)
  {
   printf("\n最高成绩的学生是：\n");
   printf("学号：%d\n姓名：%s\n三门成绩：%5.1f,%5.1f，%5.1f\n平均成绩：%6.2f\n",stu.num,stu.name,stu.score[0],stu.score[1],stu.score[2],stu.aver);
