Predict The Output

[Jishnu]

Can ne-1 explain 2 me the output of the following code ?

(Mind well, it's completely legal C code !! ; n it actually won the International Obfuscated C Code Contest.)

#include<stdio.h>

Since it's an IOCCC entry, go find the explanatory notes which come with the program.

[Jishnu]

what is the relevance of the above link ?

[~s.o.s~]

Nothing, he was just being his usual self... ;-)

Anyways, go to this site and read the hint files which come along with the code to get an understanding of whats going -- though if you are a beginner to intermediate programmer, it would be difficult for you make any sense.

[Ancient Dragon]

that program is pure nonsense -- it will not compile.

Code tags won't help here! I guess in some countries April first falls on a later date! This code has only one purpose, to test the mental constipation of the typical C programmer.

Yea, I was trying to compile it in a *.cpp file, which doesn't work. compiles ok as *.c

Why don't you run it and find out without needing to predict?

> can anybody predict the output of this code?
I predict a slap for
- bumping a dead thread
- hijacking a dead thread
- not using code tags
- using void main

Since the program depends on user input, the output would depend on the input.
I'll type in '5' and watch the program do bugger all - how's that?
Notwithstanding the comedy of errors which iamthwee posted.

[Narue]

>- bumping a dead thread
Bumping is fine as long as it's on-topic. It's debatable whether this particular bump is relevant, but I left it nonetheless.

>- hijacking a dead thread
This is tied to bumping a dead thread, and I decided just to let it slide this time.

>- not using code tags
I almost added code tags, but then I noticed that the code had no formatting, so code tags would be useless. I didn't have the time or interest to format the code for the dude.

>- using void main
I'm afraid for this the sentence is death.

Perhaps, you should familiarize your self with DaniWeb rules and FAQs. You've just hacked a thread with an entirely different problem. You should start a new thread instead. Also, the last post was made more than 8 months ago.

One more point, you are not likely to get help on DaniWeb unless you post your efforts along with your problems.

Following this will help you a long way. :)

Oops I fear I've repeated the advice!!
