Writing a structure into a file

I am using the following code

Code:

typedef struct A {

int x;

int y;

int  z;

};



int main(void) {



 struct A A;

 struct A B;

FILE *fp;

A.x = 80000;

A.y = 40000;

A.z = 12345;



printf("%d %d %d\n", A.x, A.y, A.z);

fp = fopen("file.txt", "wb");

fwrite(&A, sizeof A, 3, fp);

fclose(fp);

fp = fopen("file.txt", "rb");

fread(&B, sizeof B, 1, fp);

fclose(fp);

printf("%d %d %d\n", B.x, B.y, B.z);

return 0;

}

But the file.txt is containing junk values when i open it . Please let me know what is wrong in my program.

Thanks,
Zaheer

Re: Writing a structure into a file

Because you are writing it in binary mode.

Because you have assigned the value to int type variable beyond its range.
