为什么运行不出结果。

#include"stdio.h"
struct student
{char rcord[10];
char name[10];
char phone[12];
char qq[20];
}stu={"11","22","33","44"},stu1;
void main()
{
FILE *fp;
fp=fopen("c://p.txt","wb");
rewind(fp);
fwrite(&stu,sizeof(stu),1,fp);
rewind(fp);
fread(&stu1,sizeof(stu1),1,fp);
fclose(fp);
printf( "%s\t%s\t%s\t%s\n",stu1.rcord,stu1.name,stu1.phone,stu1.qq);

}

fp = fopen("p.txt", "wb"); //C盘有权限要求，可以改一下文件存放地址
fwrite(&stu,sizeof(stu),1,fp);不能作为整体进行写入，你可以改成
fwrite(stu.name, sizeof(stu.name), 1, fp);
fwrite(stu.phone, sizeof(stu.phone), 1, fp);
fwrite(stu.rcord, sizeof(stu.rcord), 1, fp);
fwrite(stu.qq, sizeof(stu.qq), 1, fp);
