int age;
char sex[3];
int qq;
};
struct friends fri1[2], fri2[2], fr1, *fr2;
int main()
{

fr2 = fri2;//it is necessary
FILE fp;
char fname[30];//like can not use
printf("Please input file name\n");
int t=fopen_s(&fp,"D:\Visual Studio 2013\Project\File\freadfwrite1.txt", "wt+");//like can not use fanme ....
printf("t is %d\n", t);
if (t != 0)
{
printf("The file can not be opened");
getchar();
exit(1);//stdlib
}
for (int i = 0; i < 2; i++,fr1++)//fr1++
{

printf("hi\n");
scanf_s("%s %d %s %d", fr1 -> name, &fr1 -> age, fr1 -> sex, &fr1 -> qq);//not [] need&

}
fwrite(fr1, sizeof(struct friends), 2, fp);
rewind(fp);//rewind the position
fread(fr2, sizeof(struct friends), 2, fp);
