Code quizz

[Bob]

Here is a little something for those of you that fancy some cool coding:

Code Select Expand

int magic(int i) {
               int j = 1337, k = 0;
               do k -= i += (i<0 ? 1 : 0) + i;
               while ((j *= 42) != 0);
               return k;
       }
What does the function magic do?

You will for sure know when you find the right answer, so please don't post it here and ruin the fun for somebody else
I will later today, or some other day, post some hints if you have problems with it (or you could send me a PM if you're impatient), and finally the solution as well I guess.

Good luck :flirty:

crash my laptop is what it did lol

doesn't really like php hehe

[Bob]

Haha :lmfao:

Try using a real programming language Jamoe, like Java or C :narnar:

[Jamoe]

hehe, I did convert it to php befor running it lol :flirty:

anyway, as I can't set apache to not ever time out and php runs out of numbers after 10 seconds I guess thats a clue. lol

Anyway, I cans see what its doing, just can't see the point lol.

what's wrong with Fortran?

[Bob]

what's wrong with Fortran?

Nothing at all, but I couldn't list all the "real" programming languages I know about, just took the first two that came to mind

Of course I could also have mentioned Fortran, Cobol, Pascal, Prolog, Lisp, Python, Assembly etc, but I didn't see the point

Seriously, can you really see what it's doing, just by looking at the code :blink:

Either you're exceptionally bright, or you don't see what it actually does (meaning, what the "general" result of the function is) :g:

[Jamoe]

ADA, Eiffel, C# nice

Prolog = Evil

[Gandalf]

You need to run it to work that out?

For shame. Easy, NEXT.

the result of the function? u mean it actually has one?

[Bob]

the result of the function? u mean it actually has one?

Yes indeed
And a quite sensible result as well...
And the whole point for you is to figure out what (which Gandy obviously thinks is quite easy :blink:)...

[Jamoe]

lol so much for php, weakly typed languages ftl

[Gandalf]

I may have it wrong, but.... PM'ed

[Jamoe]

yea, i had forgotten that php will automaticaly convert ints to floats when they go over certain sizes.

thanks to Bob for the int tip, it finally makes sense. lol
