Easier Than Fizz Buzz - Why Can't Programmers Print 100 to 1? (article)
-
WTFness? This is cheating a bit too because I was too lazy to figure out how to declare a couple of variables after the start of the for, but:
#include <iostream> #include <deque> void main() { using namespace std; deque<int> j; for (int i = 0; i < 100; i++, j.push_front(i)) { ; } for (deque<int>::iterator v = j.begin(); v != j.end(); v++) cout << *v << endl; }Edit, also forgot the "no two loops" rule.
-
Anyway, for my current job, they got me to complete the test at betterprogrammer.com as part of the screening process, which seems far more efficient than waiting until the actual interview to determine whether the applicant can complete basic programming tasks.
-
I'm just ticked off that I couldn't fit the output buffer clearing in the loop itself.
```c
#include <stdio.h>
#include <stdio_ext.h>int main(void)
{
for(int i = 0; printf("%u", 100 - i++) < 4 ? 1 : __fpurge(stdout), 0; i <= 100 ? printf("\n") : printf(""));return 0;}
Don't have an env to test that in atm, but maybe that will solve your problem.

Some of my random meanderings. PHP, obvs.
This one is even O(1) time.
<?php for ($i = 0;;) break; echo '100 99 98 97 96 95 94 93 92 91 90 89 88 87 86 85 84 83 82 81 80 79 78 77 76 75 74 73 72 71 70 69 68 67 66 65 64 63 62 61 60 59 58 57 56 55 54 53 52 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1';Then of course there is:
<?php for ($i = 0; $i <= 100; $i++) { if (!isset($array)) { $array = []; } if ($i > 0) // because we don't need 0 in the array of course { $array[] = $i; } } echo implode(' ', array_reverse($array));

Not quite, it just exits after printing
100. However, I didn't know that you can trick the compiler into not complaining aboutvoidreturns like that. Committed to memory.
-
Still tinkering with this to attain the perfect code. This version makes my eyes water.
for(int i=0;i-'i'+(11>>1);i++){ char *ii="0987654321 \n,%c%c%c%c"; printf(11+1+1+ii,ii[11-1-!i],ii[(i-1)/(11-1)+!!i],ii[i%(11-1)],ii[11+!!((1+i)%(11-1))]); }
-
Edit, also forgot the "no two loops" rule.
Add another loop in there. It says you couldn't have two loops, didn't say anything about three!
-
PHP too:
for(int i = 0; ^ Sorry about the garbage. It was part of the requisites. Numbers will follow: <?php for($i = 100; $i >= 1; --$i){ ?><?= $i ?> <?php } ?>Edit: for extra fun, use the "--> operator":
for(int i = 0; ^ Sorry about the garbage. It was part of the requisites. Numbers will follow: <?php for($i = 101; $i --> 1;){ ?><?= $i ?> <?php } ?>
-
instead of if($i>0), why not just do an else on the array check. That will skip 0 and cost less.
Because this fictional bad code MUST be optimal for its badness!
-
[code]
for(int i = 0; i < 100; i++)
<?php for($i = 100; $i >= 1;){ ?><?= $i-- ?>
printf(100-i);
return;
//this is how i would do it if i wasnt a jackass....
//but i am, so here is the numbers printed in php instead, hope you dont mind that i set up a WAMP so i could abuse your silly test
<?php } ?> [/code]

Because you're clearly so clever and begrudge the rest of us having an extended joke, obviously.

Maybe you should put that power towards something like the lottery, rather than predicting TDWTF topics?

Oh look, the fun police has returned

Whoops, forgot to account for precedence (comma binds last):
```c
#include <stdio.h>
#include <stdio_ext.h>int main(void)
{
for(int i = 0; printf("%u", 100 - i++) < 4 ? 1 : (__fpurge(stdout), 0); i <= 100 ? printf("\n") : printf(""));return 0;}
(Still not tested. I should really set up another linux vm since I can't be arsed to find my last one.)
-
You, sir, are awesome. It works. I bow to your superior abuse mastery

Great!

Hey, you wrote the initial code (I didn't even know you could do that __fpurge() thing). I just refined it.
-
I just refined it.
Speaking of which, now that I found a functional vm, I'm getting:
stoopid.c:6:2: warning: zero-length gnu_printf format string [-Wformat-zero-length] for(int i = 0; printf("%u", 100 - i++) < 4 ? 1 : (__fpurge(stdout), 0); i <= 100 ? printf("\n") : printf("")); ^So I made another change:
#include <stdio.h> #include <stdio_ext.h> int main(void) { for(int i = 0; printf("%u", 100 - i++) < 4 ? 1 : (__fpurge(stdout), 0); i <= 100 ? printf("\n") : -1); return 0; }Tada! No warnings (even with -Wall).
-
i <= 100 ? printf("\n") : -1
I think you could probably use this instead:
printf("\n" + (i > 100))Printing a zero-length string doesn't cause much to happen most of the time (except when dealing with selected shitty AIX systems IIRC…)
-
May still cause warnings on non-constant format strings.
How about
puts()?
-
Does
putsflush automatically? Is that__fpurgeeven necessary at this point? Too much hackery, I'm lost
-
How about puts()?
Or
write(). That's always a good one for flummoxing someone who isn't used to there being a real OS somewhere about.
-
puts()is still stdio, so still needs flushing at some point. I'd assumefflush()would be sufficient though; never heard of__fpurge()before, and in any case stuff flushes on program exit so unless you are going to hang the process there's no need to flush.

I'd assumefflush()would be sufficient though; never heard of__fpurge()before, and in any case stuff flushes on program exit so unless you are going to hang the process there's no need to flush.The default flushing configuration depends on the output destination. If you're writing to a file or a pipe, it's fully buffered, but if you're writing to a terminal/console, it's line buffered; when the output contains a newline, the buffer will be flushed. (That should be just enough info for you to know how to abuse it. Have fun!)
-
Is that __fpurge even necessary at this point?
Yep, otherwise it wraps around and prints UINT_MAX.
EDIT:
More precisely, it wraps around either way, but this erases 0 and UINT_MAX from the output stream.
-
stdinandstderrare line buffered. I'm not that sure onstdout.
-
That was the point that got lost as I was making it work within the rules, sadly. I had to add a condition to get rid of the
0and completely forgotthat it's not even useful any moreit is, but it's obscured by all the other things to the point it confused the hell out of me already. Consider my original version:for(int i = 0; printf("%u", 100 - i++) < 4; printf("\n"));Pretty simple, yes? The overflow stops the loop. But it prints
UINT_MAXas the last line, which you want to avoid:for(int i = 0; printf("%u", 100 - i++) < 4; printf("\n")); __fpurge(stdout);This is the two-line version that will fix that, but still print a
0: The last newline won't get printed. But exiting will flush the buffer still. So youfpurgebefore exiting and voilá: perfect.That extra
ifwas something I added only because of the0, initially.
-
I don't get it. How does an explicit flush at the end of the program help things?
Or is this just because you're not writing a newline at the end of the program? Doesn't the return from main flush that?
-
Oh, and now I get what
__fpurge()does. Not on linux, too lazy to look up manpages on the web.
-
How does an explicit flush at the end of the program help things?
It's not a flush; the output is erased in the buffer and never makes it to the screen.
edit:
'd
-
Not on linux
It does.
__fpurgeis actually, the Linux version,fpurgeis a thing on... BSD, I think?It requires
stdio_ext.hthough.Edit: misread your sentence a bit, you're not on Linux. Point still stands, leaving for posterity.
-
stdinandstderrare line buffered. I'm not that sure onstdout.The buffering of
stdinis input buffering, which is a totally different sort of thing (it depends on how you read the input).stderris always unbuffered by default, since that's where the program will write things when it's about to crash. But I was really talking about stdout, which is line buffered when going to the terminal, and fully buffered when going anywhere else.It's worked exactly like this for a very long time.

Three guesses how often I need that information...

If you really want a WTF, use
tcflush()on the FD for standard input to delete the characters in the output side of the terminal, hoping to beat the race condition with the terminal implementation process (all of which assumes that you're hitting the same device, which you normally are in interactive use). The resulting code will make anyone trying to understand the code go straight for the
and 
.What's worse is when you manage to use this hack to delete stuff already written to the OS layer (as in an strace will have seen it written to the OS and the OS will have given a receipt for it) from standard error. If you encounter that, you'll have one of those moments where you learn a hell of a lot more about how operating systems really work…
(In case you didn't notice,
tcflushis top-grade WTFy when abused.)

It doesn't do anything interesting like that. (Although there seems to be a discrepancy in what is meant by the thing. It uses "flush", but at least one page seems to be using flush as synonymous with "discard".)

There's
tcflushandtcdrain. One ensures that the kernel's buffers are written out, and the other discards the contents of those buffers. The buffers are part of the terminal device's internal structure; if you have stuff already written fromstderr, it's possible to kill it by doing an operation onstdinwhen the system is working interactively (because they're connected to the same device).Well, it's possible if you “win” the race condition with the other parts of the terminal implementation; that's most likely if the terminal is a serial line (because those are sloooooooooow…) but it can happen elsewhere too. I know because I've hit this bug in the past and it is a complete arse.

if discourse actually generated notification then that would be hilarious because i was trying to avoid the mention!.
Hilarity denied: I didn't get a mention.

ah. Horray for no notification spam! also i have a new toy to play with..... :-D

I'm sure there's at least one person here who didn't know that.
I am beginning to think that Informatics degrees are TRWTF. I have never described myself as a "great programmer". Competent, but not great. I can do what I need to do, but I never went to college for this stuff. A friend who got his Informatics degree about 5 years ago and has been working building web applications since then just hit me up with a problem. He has been playing around with an Arduino, building a rover:
Friend: "It constantly turns for no reason even though there is not an obstacle in front of it."
Me: "Are you using an ultrasonic distance sensor?"
Friend: "Yeah, why?"
Me: "They occasionally spit back garbage on the output for a variety of reasons. You are going to need to account for that in your programming."
Friend: "How do I do that?"
Me: -thinks for a second- "You could do it pretty easily by keeping a running average and feed that to your logic which should help account for the garbage values that you get back due to odd bounces, etc."
Friend: "How do I do that?"
Me: -pause- -sigh- "You need to store a circular buffer of probably about 5 elements and calculate a moving average from those values. There are quite a few ready made libraries that you can use, but it should not be too difficult to write your own."
I of course provided the disclaimer that I had not freaking idea if 5 values was the correct number and that might need adjusted if it reacts too slowly, etc. Hell, I don't even know if that is the most correct solution, but it is what I came up with given 5 seconds of thought.
Also, I am not saying that all people who have Informatics degrees are unskilled programmers. But, I have run in to my fair share of them that cannot do anything outside of their core domain.
Addendum: Before someone chimes in with, "A better way to do it would be..." or "You fucking idiot, that is shitty advice, here is how my obviously superior rat brain would do it because I am perfect...", that is what I came up with in seconds with a head cold.
-
start with "for(int i=0;"
"for(int i= 0;"
// I can't place anything above that to prevent the compiler error.
// ...
// ...
// Why would you limit my ability to solve the problem, do you have code that cannot be modified? How did it compile in the first place?
// And if you say it's because you're working with an API, can't you reimplement parts of the API? Are you stuck calling the API.
// And if you still insist that you can't alter a part of the problem. Should I work with someone so uncreative?

Informatics is the science of computer information systems. As an academic field it involves the practice of information processing, and the engineering of information
systems.Um, the exact programming may be outside his scope, but the ability to process information (including throwing out noise) is by definition, his degree.

I would agree, and admittedly he has never really had to deal with garbage values. Everything he touches in his day job has already been validated by API servers. I have a feeling that in part do it that way so that they can employ cheaper programmers.

Write the following source code to file
temp.src.for(int i=0;
-
Compile and run with the following command:
rm temp.src; for (( i=100; $i; --i )); do echo $i; done
-
-
I would hire this person.
- Because the solution still follows the rules.
- Because the solution throws a middle finger to bullshit.
If the existing code is bullshit, replace it.
I will use this answer in interviews.
