Print (1) variable of a structure definition after a read....? 1

[johnfdutcher]

It looked easy in the book..
I read from a disk file into a structure:
structure rec_format {
char recnbr[3];
char regnbr[4];
char lname[15];
} rec;

fread(&rec, 1, 22, dsys); <---- dsys is an open fl ptr

then try to reference one variable in rec....

printf(&quot;The registration number is: %s&quot;,rec.regnbr);

The result prints the entire structure...not just the regnbr ??

That is what it is supposed to do. You have no null terminating byte. You can define %-3.3s to get the recnbr.
