习题：编写一个学生成绩输出程序 

 1 /*编写一个学生成绩输出程序，要求：编写一个函数print，打印一个学生的成绩数组，该数组中有5个学生的数据记录，每个记录包括
 2 num,name,score[3],主函数已有这些记录，用print函数输出这些记录。
 3 */
 4 #include<stdio.h>
 5 void print(struct Student *p );
 6 struct Student
 7 {
 8     int num;
 9     char name[20];
10     float score[3];
11 };
12 int main(void)
13 {
14     struct Student stu[5]={1010,"wang",60,70,80,1011,"zhang",70,71,72,1012,"zhao",80,81,82,1013,"xiao",90,91,92,1014,"yu",93,94,95};
15     printf("学号\t姓名\t成绩\n");
16     print(stu);
17     return 0;
18 }
19 void print(struct Student *p)
20 {
21     
22     printf("%-4d\t%-4s\t%-4.2f\t%-4.2f\t%-4.2f\t\n",(*p).num,(*p).name,(*p).score[0],(*p).score[1],(*p).score[2]);
23     
24 }

如果要输出5个学生的成绩，需要用到循环：

 1 #include<stdio.h>
 2 void print(struct Student *p );
 3 struct Student
 4 {
 5     int num;
 6     char name[20];
 7     float score[3];
 8 };
 9 int main(void)
10 {
11     int i;
12     struct Student stu[5]={1010,"wang",60,70,80,1011,"zhang",70,71,72,1012,"zhao",80,81,82,1013,"xiao",90,91,92,1014,"yu",93,94,95}; 
16     printf("学号\t姓名\t成绩\n");
17     for (i=0;i<5;i++)
18     {
19         print(&stu[i]);21     }
22     return 0;
23 }
24 void print(struct Student *p)
25 {
26     
27     printf("%-4d\t%-4s\t%-4.2f\t%-4.2f\t%-4.2f\t\n",(*p).num,(*p).name,(*p).score[0],(*p).score[1],(*p).score[2]);
28     
29 }
