这里是4名学生一门成绩的排序，不过中间还有生日，希望能给你带来点灵感吧！
通过比较，进行交换达到的排序。
源代码如下：
#include
struct student_record
{
char name[8];
struct birth
{
int year;
int month;
int day;
}date;
int score;
}student[4];
void main()
{
struct student_record student[4];
struct student_record stu;
int i,j;
printf("please input date:\n");
for(i=0;i<4;i++)
scanf("%s%d%d%d%d",student[i].name,&student[i].date.year,
&student[i].date.month,&student[i].date.day,&student[i].score);
printf("OUTPUT:\n");
printf("NAME BIRTH SCORE\n");
for(j=1;j<=3;j++)
for(i=0;i<4-j;i++)
{

if(student[i].score {
stu=student[i];
student[i]=student[i+1];
student[i+1]=stu;
}
}
for(i=0;i<4;i++)
printf("%s %d,%d,%d %d\n",student[i].name,student[i].date.year,
student[i].date.month,student[i].date.day,student[i].score);
}

M门课程要先知道M是多少。不然没办法定义结构体。变量多少不知道。
