Solutions for the Kernighan and Ritchie

[anotherlin]

Hi everyone,

I've read the Kernighan and Ritchie some time ago, and then again, but
this time I've done the full set of exercises. I figured it would be
nice to share them :

http://linkefong.free.fr/downloads/t...utions-1.0.zip

Your comments are welcome.

I've of course didn't peek in Tondo and Gimpel's book or Richard
Heathfield.

Regards,

It might be nice to merge these solutions with Richard's collection
that is online.

It's true that I started the collection, but I have long since palmed it
off onto the clc wiki, which may be found at this URL:

The K&R2 solutions page is: http://clc-wiki.net/wiki/K%26R2_solutions

I'll be glad to see them added to the clc-wiki. The admin has my
blessing to upload them.

I've basically answered all exercises, even those missing from
Richard's collection.

But first, is there somebody to check them for correctness? Any
comments?

Thanks for getting his/her blessing first. Please include a link to the
original site when uploading them.

After uploading them they can be edited. So I would suggest upoading
them then posting links to them here asking for comment.

Looks good. That was a quick glance and if I have time I'll look
again. On one style issue, I was baffled by the large number of blank
lines. I won't make a fuss about style but it looked odd to me.

I spent a bit more time on one that I am currently familiar with (the
RPN calculator from chapter 4) and I am disappointed to see you also
have lost the original (correct in my opinion) K&R design of passing
getop the buffer size so you can prevent overflow. I'd count this as
a error.

The test driver for exercise 4.2 does not test the atof() function:

int main ()

{
printf("%g\n", 123.45e-6);
return 0;
}

Probably, you meant to do this:

#include <stdio.h>
int main ()

{
printf("%g\n", atof("123.45e-6"));
return 0;
}

Since you like sharing your knowledge, you might be interested in
contributing to the free software community by adding you project to
spammy (spamspam.spam. gnu.org).

Or rather, do not, since I cannot find an Earthly reason why anyone
would think answers to K&R exercises have anything to do with the
contents of that page.

Freedom? Freedom to advertise where it isn't wanted, apparently.

Well, I prefer things well separated. I use vi inside an 80x70
characters
xterm so there doesn't seem to be so much of them. I agree things can
look
differently and styles are a matter of personal taste.

I spent a bit more time on one that I am currently familiar with (the
RPN calculator from chapter 4) and I am disappointed to see you also
have lost the original (correct in my opinion) K&R design of passing
getop the buffer size so you can prevent overflow. *I'd count this as
a error.

I started with the getop() function p78 of my 2nd edition book (41st
printing)
and there is no buffer size (prototype is int getop (char s[])). In
fact, none
of the exercises of this chapter specifically ask for checking buffer
overflow.
However, I agree that it would have been better a better answer.
