程序通过定义学生结构体数组，存储了若干名学生的学号、姓名和3门课的成绩。函数fun的功能是将存放学生数据的结构体数组，按照姓名的字典序（从小到大）排序。

#include <stdio.h>
#include <string.h>
struct student {
long sno;
char name[10];
float score[3];
};
void fun(struct student a[], int n)
{
____1______ t;
int i, j;
for (i=0; i<____2_____; i++)
for (j=i+1; j<n; j++)
if (strcmp( ____3_____) > 0)
{ t = a[i]; a[i] = a[j]; a[j] = t; }
}
main()
{ struct student s[4]={{10001,"ZhangSan", 95, 80, 88},{10002,"LiSi", 85, 70, 78},
{10003,"CaoKai", 75, 60, 88}, {10004,"FangFang", 90, 82, 87}};
int i, j;
printf("\n\nThe original data :\n\n");
for (j=0; j<4; j++)
{ printf("\nNo: %ld Name: %-8s Scores: ",s[j].sno, s[j].name);
for (i=0; i<3; i++)
printf("%6.2f ", s[j].score[i]);
printf("\n");
}
fun(s, 4);
printf("\n\nThe data after sorting :\n\n");
for (j=0; j<4; j++)
{ printf("\nNo: %ld Name: %-8s Scores: ",s[j].sno, s[j].name);
____4_____

printf("\n");
}

1. struct student
2. n - 1
3. a[i].name, a[j].name
4. for (i=0; i<裤含3; i++)
5. printf("胡和笑%6.2f "棚孝, s[j].score[i]);

正确答案颂好芦是野带：
1. struct student
2. n - 1
3. a[i].name, a[j].name
4. for (i=0; i<袜灶3; i++)
5. printf("%6.2f ", s[j].score[i]);
