求救!不知道哪儿错了.

#include "stdio.h"
#define N 8
void input()
{
struct student
        {
         int num;
         char name[18];
         struct date
                {
                 int year;
                 int month;
                 int day;
                }brithday;
         char address[50];
         float score[4];
         float ave;
        }stu[N];
int i=0,j;
char flag;
printf("\nDo you want input student's information(y or n):");
scanf("%c",&flag);
while(i<N&&flag=='y')
      {
       stu[i].num=i+1;
       printf("\nPlease input NO.%d student's information:",stu[i].num);
       printf("\nAame:");
       scanf("%s",stu[i].name);
       printf("\nBrithday:");
       scanf("%d%d%d",&stu[i].brithday.year,&stu[i].brithday.month,&stu[i].brithday.day);
       printf("\nAddress:");
       scanf("%s",stu[i].address);
       printf("\nScore:");
       for(j=0;j<4;j++)
          {
           scanf("%f",&stu[i].score[j]);
           stu[i].ave+=stu[i].score[j];
          }
       stu[i].ave=stu[i].ave/4;
       printf("Do you want continue? y or n.");
       scanf("%c",&flag);
       getch();
       i++;
      }
}

运行上面的程序,在输入地址之后程序就不再向下运行了,我找了半天不知道哪儿错了,请哪位高手帮忙找找并解释下,谢谢!

你的程序能编译？？？我晕！连mian函数也没有。帮你改好了，其它功能自己看着办，主要问题是scanf()函数在作怪。 #include <stdio.h> #include<conio.h> #include<process.h> #define N 8 struct student { int num; char name[18]; struct date { int year; int month; int day; }brithday; char address[50]; float score[4]; float ave; }stu[N]; void input() { int i=0,j; char flag; printf("\nDo you want input student's information(y or n):"); scanf("%c",&flag); if(flag=='y') while(1) { stu[i].num=i+1; printf("\nPlease input NO.%d student's information:",stu[i].num); printf("\nAame:"); scanf("%s",stu[i].name); printf("\nBrithday:"); scanf("%d%d%d",&stu[i].brithday.year,&stu[i].brithday.month,&stu[i].brithday.day); printf("\nAddress:"); scanf("%s",stu[i].address); printf("\nScore:"); for(j=0;j<4;j++) { scanf("%f",&stu[i].score[j]); stu[i].ave+=stu[i].score[j]; } stu[i].ave=(float)stu[i].ave/4; printf("The %d ave is: %f\n",i+1,stu[i].ave); printf("Do you want continue? y or n."); flag=getch();/*不能用scanf*/ if(flag=='n') exit(1);/*退出*/ i++; if(i==N-1)break;/*退出循环*/ } else exit(1);/*退出*/

} void main() { input(); }
