有n个学生，每个学生的数据包括学号、姓名和3门课的成绩，用键盘输入n个学生的数据

已帮你改好

#include
#define MAX 100
struct Student
{
char name[20];
int number;
int s[3];
int average;
};struct Student stu[MAX];
int main()
{
int n,i,j,m,max;
printf("请输入人数:");
scanf("%d",&n);
printf("请依次输入每个学生的姓名、学号、及三门课成绩:\n");
for(i=0;i {
printf("请输入第%d人的数据:\n",i+1);
scanf("%s%d",stu[i].name,&stu[i].number);
for(j=0;j<3;j++)
scanf("%d",&stu[i].s[j]);//========================这里加个&
printf("/n");
}
for(i=0;i {
printf("%s%d",stu[i].name,stu[i].number);
for(j=0;j<3;j++)
printf("%d",stu[i].s[j]);
printf("\n");
}
for(i=0;i {
stu[i].average=0;
for(j=0;j<3;j++)
stu[i].average+=stu[i].s[j];
stu[i].average=stu[i].average/3;
}
max=stu[0].average=0;
for(i=0;i if(stu[i].average>max)
{
max=stu[i].average;
m=i;
}
printf("平均分最高同学数据:\n");
printf("%s%d%d%d%d%d%d",stu[i].name,stu[i].number,stu[i].s[1],stu[i].s[2],stu[i].s[3],stu[i].average);
return 0;
}
