[求助]打开关闭文件又怎么了？又错了。。。。。

编译正确，但运行后一闪而过，怎么回事！！
#include<stdio.h>
struct stu
{
int round[3];
int press[3];
float angle[3];
};
struct beng{
char type[12];
int num[4];
struct stu state;
}data[12],*pp,*qq;

main()

{

FILE *fp;

char ch;
char b[12];

int i;

pp=data;

if((fp=fopen("c:\\WIN-TC\\projects\\stu_list.txt","wb+"))==NULL)

{

printf("Cannot open file strike any key exit!");

getch();

exit(1);

}

printf("input the data:");

for(i=0;i<12;i++,pp++)

{ scanf("%s,%4d,%3d,%3d,%3f",pp->type,&pp->num,pp->state.round,pp->state.press,pp->state.angle);

pp=data;
fwrite(&pp,sizeof(struct beng),12,fp); }
rewind(fp);
fread(&pp,sizeof(struct beng),12,fp);

printf("\n\ntype\tnumber state.round state.press state.angle\n");

for(i=0;i<12;i++,pp++)

{printf("%s\t%7d%7d%7d%7f\n",pp->type,pp->num,pp->state.round,pp->state.press,pp->state.angle); }

fclose(fp);

}
