it's not hard.

这是根据你提供的结构体写得。你自己看这加进代码吧

#include#includestructstu{charname[32];intenglish;intchinese;intmath;..n门课程};voidmain(void){inti,score,average;charNAME;structstu*STU[m]//m为已知的学生个数for(i=0;iname,NAME);printf("english:")scanf("%d",&score);STU[i]->english=score;..依次类推}printf("要查询的学生姓名：")scanf("%s"，NAME)；for（i=0,iname,NAME){average=(STU[i]->english+STU[i]->chinese+STU[i]->math)/n;}}for(i=0;i

int n,i;
printf("请输入学生人数，不能大于30人:");
scanf("%d",&n);
for(i=0;i<n;i++)

gets(stu[i].name);

scanf("%f",&stu[i].score);
