Написать короткую программу, которая будет генерировать максимально возможное сообщение об ошибке, в стандартном компиляторе C ++ ( gcc, cl.exe, iccили clang).
Оценка каждой записи — это количество символов в самом длинном сообщении об ошибке, выданном компилятором. Типы, включенные в ваш исходный код и цитируемые компилятором, считаются одним символом.
Мошенничество
Вы всегда можете переопределить шаблон в шаблоне в шаблоне с длинными именами, но я ожидаю чего-то креативного. Я пытался предотвратить это по последнему правилу, но, конечно, правила могут быть лучше, и я буду рад улучшениям.
Ответы:
Шаблон сообщения об ошибках весело расшифровывать. Учти это:
#include <vector>
#include <algorithm>
int main()
{
int a;
std::vector< std::vector <int> > v;
std::vector< std::vector <int> >::const_iterator it = std::find( v.begin(), v.end(), a );
}
Компиляция с gcc -c error.cpp(4.6.3) выдаст 15786 байт с самой длинной строкой из 330 символов.

Я обнаружил это, когда хотел посмотреть, поддерживает ли C ++ полиморфную рекурсию (и, как вы можете ясно видеть, это не так). Вот тривиальный пример полиморфной рекурсии в Haskell:
Prelude> let f :: (Show a) => a -> String; f x = show x ++ " " ++ f [x]
Prelude> f 0
"0 [0] [[0]] [[[0]]] [[[[0]]]] [[[[[0]]]]] [[[[[[0]]]]]] [[[[[[[0]]]]]]] [[[[[[[[0]] ...
Здесь, это требует Haskell действовать , как он конкретизирует Show x, Show [x], Show [[x]], Show [[[x]]], до бесконечности. Haskell делает это путем превращения (Show x) =>в неявный параметр функции, fдобавленной компилятором, что-то вроде этого:
type Show a = a -> String
showList :: Show a -> [a] -> String
showList show [] = "[]"
showList show (x:xs) = '[' : show x ++ showItems xs where
showItems [] = "]"
showItems (x:xs) = ',' : show x ++ showItems xs
f :: Show a -> a -> String
f show x = show x ++ " " ++ f (showList show) [x]
C ++ делает это, буквально пытаясь создать такие экземпляры, пока глубина экземпляра шаблона не будет превышена.
Основываясь на соотношении длина сообщения / длина кода, это может быть лучшим решением:

С gcc 4.2.1 генерирует ошибку error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘foofoo....foofoo’с 2 ^ 21 копиями foo. 6,291,558 байт всего. Это примерно как большой идентификатор , как я могу получить, заменив fooс foodгенерирует ICE.
Аналогично VJo:
a.cpp:
int main() { return
#include "a.cpp"
#include "a.cpp"
}
g ++ a.cpp
производит много вывода (по крайней мере 2 гигабайта, прежде чем я его убил)
Следующий код основан на фактической ошибке, с которой я однажды столкнулся.
template <int i>
void bar();
template <int i>
void foo()
{
bar<i>();
char baz[i];
}
template <int i>
void bar()
{
foo<i-1>();
}
int main(void)
{
foo<2000>();
return 0;
}
(используя gcc)
Довольно очевидная рекурсия шаблона, но так как я использовал ftemplate-depth=100000для этого запуска, это не выдает ошибку. Истинный источник сообщений об ошибках исходит char baz[i];, который выдает ошибку, когда iпадает до -1.
Примерно через полчаса я сижу на 21 000 ошибок компилятора , 300 000 строк сообщений об ошибках и 280 мегабайт оперативной памяти, используемой компилятором. И это не показывает никаких признаков остановки.

Час спустя, теперь на 36 000 ошибок компилятора , 504 000 строк сообщений об ошибках и 480 мегабайт ОЗУ … и все еще продолжается.

Я случайно наткнулся на это:
#include<functional>
#include<algorithm>
#include<array>
#include<stdexcept>
int main(int argc,char** argv){
std::array<double, 3> arr;
arr[0] = 0; arr[1] = 1; arr[2] = 1;
if (std::any_of(arr.begin(), arr.end(),

}
}
На c ++ x11 он выдает 44 КБ сообщений об ошибках, в которых компилятор пытается сказать: Пожалуйста, определите местозаполнитель для первого аргумента, если вы определите его для второго.
Посмотри на Ideone .
C ++
На основе решения BЈовић:
Файл: golf.cpp:
#include "golf.cpp"
#include "golf.cpp"
Выполнение этого в G ++ не закончится, однако, я вычислил длину ошибки, которую он в конечном итоге испустит, примерно 85 * 2 ^ 140 терабайт.
C ++ 11 вариационных шаблонов (69 символов)
template<int... p>
void f()
{
return f<0,p...>();
}
int main() {
f();
}
Конфигурируя максимальную глубину создания шаблона, вы можете установить длину ошибки. Вот пример использования GCC 4.8.1 с глубиной шаблона по умолчанию (900):
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}] ‘return f <0, р …> (); ^ prog.cpp: 4: 22: требуется рекурсивно из ‘void f () [with int … p = {0}]’ prog.cpp: 4: 22: требуется из ‘void f () [с int .. .p = {}] ‘prog.cpp: 8: 4: требуется отсюда 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}] ‘return f <0, p …> () ; ^ prog.cpp: 4: 22: требуется рекурсивно из ‘void f () [with int … p = {0}]’ prog.cpp: 4: 22: требуется из ‘void f () [с int .. .p = {}] ‘prog.cpp: 8: 4: требуется отсюда 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}] ‘return f <0, p …> () ; ^ prog.cpp: 4: 22: требуется рекурсивно из ‘void f () [with int … p = {0}]’ prog.cpp: 4: 22: требуется из ‘void f () [с int .. .p = {}] ‘prog.cpp: 8: 4: требуется отсюда

Также вы можете добавить еще десять символов и использовать недопустимое целое число без знака, чтобы увеличить длину ошибки:
template<unsigned int... p>
void f()
{
return f<0-1,p...>();
}
int main() {
f();
}

Вот пример работы на ideone.
82 байта: этот работает аналогично подходу Джои Адамса , но сообщение об ошибке будет расти в геометрической прогрессии по отношению к -ftemplate-depth(потому что std::set<T>на самом деле std::set<T, std::less<T>, std::allocator<T>>).
Так (x = -ftemplate-depth) >= 28, будет 1460 × 3 x-27 + 269x — 5381 байт сообщений об ошибках (скомпилировано gcc 7.2.0). То есть в настройках по умолчанию (x = 900) теоретически будет выдано около 4,9 × 10 419 байт сообщения об ошибке .
Обратите внимание, что без returnоператора сообщения об ошибках будут создаваться только в конце компиляции. (поэтому в настройках по умолчанию вы не получите сообщения — сначала вам не хватит памяти.)
Предупреждение: компиляция этой программы будет занимать много памяти.
#include<set>
template<class T>T f(T a){return f(std::set<T>());}int main(){f(0);}Попробуйте онлайн!
Это дает бесконечный вывод на GCC 5.2 и Clang 3.6 (на Clang требуется -ferror-limit=0, на GCC работает с настройками по умолчанию):

Это вилочная бомба, где n = 40.

- 174 байта: квадратичный взрыв с несколькими сообщениями об ошибках:

Transcript[]
- GoAnimate Maze Game Announcer: WARNING: The following game contains scary scenes that may be too intense for younger players. Player discretion is advised.
- Caillou: Okay. Let’s do it. [Caillou plays the Maze Game on GoAnimate when an error appeared.]
- Barney Error Announcer: We interrupt your Windows XP session for a [Barney appears on the screen.] Barney Error. Barney was killed by Zola. [Barney shrinks 15 degrees, an orange square appears as the lair, black tape and a bomb appear.] Zola placed Barney inside his lair tied him up and put a bomb in there. It will explode in 404 years. I want to remind you. Do not turn off your Windows Longhorn. REPEAT: Do not turn off your Windows XP. Be careful. Because if you do, you get a strike. LAST REPEAT: If you do, you get a strike. You get 500 chances! [The chance/turn off count appears next to Barney’s lair.]
- Caillou: You know what?! Screw You! I can do whatever I want! [Caillou tries to turn off your computer, cut to black screen that says «Does not shut down. Barney Error intact.» The background changes to green.]
- Barney Error Announcer: Hey! Did you turn your Windows XP computer off when I told you not to? That is not allowed on Barney Errors. The timer will be cut in half the next time you do it.
- Caillou: Well, if that’s how you want to play it! [Caillou turns it off again, the program came back on.] You turned it off again! The timer is going to be cut in half. It is now 4800 hours. [Caillou turns it off again, the program came back on again, the background is changed to yellow.] Why do you always turn off your Windows XP computer? You know that makes Barney angry! Another time reduction has occurred. [Caillou turns off yet again. The background changes to orange.] What? You turned off 4 times! This is your last good chance. Another time reduction has occurred.
- Caillou: If I block this, it will work. Let’s see. [Caillou blocks the screen.] Yes! (x6) [The Barney Error program unblocked.] Oh, no! It didn’t work! How can this be?
- Barney: How dare you block me? You know I need to see you. That counts as turning it off. Another time reduction has occurred. [Barney turns into evil mode with red eyes, and pointy teeth.] We Are Now In Evil Mode! Leave your system alone.
- Caillou: Can you just shut up already Barney?! It’s giving me a mild headache! [Caillou turns it off again.]
- Barney: Why are you still turning off your system? It makes me mad. Another time reduction has occurred.
- Caillou: Hey, Barney, I have something for you.
- Barney: Okay! What is it?
- Caillou: This. [A sign says «We Hate You Barney!» appears flying past Barney.]
- Barney: How dare you block me again? That also counts as turning it off. Another time reduction has occurred. This time, don’t touch it!
- Caillou: That does it. I’m breaking the computer screen. Hi-yah! [The screen repairs itself.] The computer screen rebuilt itself? How?
- Barney: Breaking the computer screen also counts as turning it off. Another time reduction has occurred. Now look, 2 hours. [Caillou almost turns off again.]
- Caillou: Stupid Barney! Can’t he just give up already?! [Cuts to a screen seeing a yellow circle with an exclamation mark. Cut To The background, the screen is dark.]
- Evil Barney: You! (3x) Why do you always turn it off? Another time reduction has occurred and it’s now 1 hour!
- Caillou: Yawn. I’m tired. Let’s shut it down for good. [Caillou turns it off, very tired.] Son of a bitch!
- Evil Barney: [after hearing 3 notes on the piano] Why do you always turn off your system so much? Are you trying to ignore me? Another time reduction and it’s now 30 minutes! Leave your system alone.
- Caillou: I’m going to change the chance count to 1,000,000 and turn off count to 0. [A mouse cursor appears, there is «Change Value» page. A mouse cursor presses «Submit», a yellow circle with an exclamation point appears. The chance count is rearranged to 9 and turn off count rearranged to 11.]
- Evil Barney: Hey! You are not allowed to change the amount of chances and turn off counts! That also counts as turning off your Windows Longhorn computer. The timer is now down to 15 minutes! [The GoSkype app appears on the screen, Caillou sees an incoming call: rosiethecool242 next to a person underneath two buttons: the one for the green — decline and the one for the red — ignore.]
- Caillou: Rosie’s calling me on GoSkype. [The GoSkype app is gone away.]
- Evil Barney: You cannot answer GoSkype calls during a Barney Error! That also counts as turning off your Windows Longhorn computer! The timer is now down to 10 minutes.
- Caillou: This has got to be the dumbest thing that I’ve ever seen! Really dumb! I’m turning off your system. [Cut to another background with a red circle with three exclamation points.]
- Evil Barney: I can’t freaking believe you are still turning off your Windows XP computer. Stop turning it off! The timer is down to 5 minutes.
- Caillou: That’s it, Barney! Take this! [Caillou punched Barney out of the lair. The background changes to blue. A buzzing noise is heard.]
- Barney: Okay! I had enough of turning it off! You punched me, and that’s the last time you did something wrong! Yeah, that’s right! The Timer Is Down To 30 Seconds! You are lucky that I will give you an extra chance, but you’ve got to enter the code within 30 seconds!
- Caillou: This shouldn’t be too difficult. [Caillou turns off the system one last time. The bomb got exploded.]
- Barney: I’m sorry, but the code is EXTREMELY WRONG! Here Is The Correct Code: 4 8 15 16 23 42! If you have entered that, you would be safe and continued playing your Windows XP computer, but that didn’t happen, so I will CRASH YOUR COMPUTER RIGHT NOW! [Cut to a BSOD: Black Screen of Death, which is similar to BSOD: Blue Screen of Death next to an emoji with a X_X face.]
- Black Screen of Death Narrator: Your computer is dead, and you have to upgrade to Windows Vista. Thank you for using Windows Longhorn. Goodbye.
- Caillou: Oh, no! My computer died! I have to press the «Upgrade» button to upgrade Windows Vista. [A mouse cursor reappears pressing the «Upgrade» button, the upgrading of loading has complete to 100%. A mouse cursor presses the «Start» button after done upgrading Windows Vista. The Windows Vista session is introduced, the setup page is on the screen.] Next time, I’ll play your Windows Vista computer instead of Windows XP. I hope this Barney Error is over. [The time card shows: After the setup completed…] Wow! This is a good version of Windows Vista. Much this is dumb. Over and outLonghorn.
Насколько я знаю, join() присоединяет массив строки к другой строке. Например, "-".join(["a", "b", "c"]) вернет abc.
Кроме того, вы начали с определения temp как строки, но позже обратитесь к нему с двойным индексом, почти как если бы это был массив. Насколько я знаю, вы можете ссылаться на символ в строке с одним вызовом индекса. Например, a = "foobar", a[3] возвращает b.
Я изменил ваш код на следующее. Инициализация массивов для начала, чтобы избежать проблем с индексацией.
def lcs(x,y):
c = len(x)
d = len(y)
plot = [[0 for j in range(d+1)] for i in range(c+1)]
temp = [['' for j in range(d+1)] for i in range(c+1)]
highestcount = 0
longestWord = ''for i in range(c):
for j in range(d):
if x[i] == y[j]:
plot[i+1][j+1] = plot[i][j] + 1
temp[i+1][j+1] = ''.join([temp[i][j],x[i]])
else:
plot[i+1][j+1] = 0
temp[i+1][j+1] = ''
if plot[i][j] > highestcount:
highestcount = plot[i][j]
longestWord = temp[i][j]return plot, temp, highestcount, longestWord
x = "AGCTGGTCAG"
y = "TACGCTGGTGGCAT"
test = lcs(x,y)
print test
