Re: [ilug-cal] [OT]Problems with gcc

[Siddhartha Basu]

Hi,
Try to avoid scanf function as much as possible,
instead use fgets and sscanf combo for stdio which has
got much more efficient error checking. This is most
recommended procedure as i have found in comp.lang.c
group. For a much better explanation follow this link.

Check out question no 12.12 and 12.20
