廢話不多說，我們直接看程式碼吧。

{% code lineNumbers="true" %}

```c
E((ck?main((z?(stat(M,&t)?P+=a+'{'?0:3:
execv(M,k),a=G,i=P,y=G&255,
sprintf(Q,y/'@'-3?A(*L(V(%d+%d)+%d,0)
```

{% endcode %}

公主與王子他們從此過著幸福快樂的日子，劇終。

蛤，什麼？你說還沒把整個 C 語言程式設計給說清楚嗎？

好啦，老實說，我也不太確定上面那個程式碼範例可以做什麼。程式碼的來源是在 2001年的 [International Obfuscated C Code Contest](https://www.ioccc.org/)[1 ](https://beej.us/guide/bgc/html/split/footnotes.html#fn1)其中一段程式碼，有個很厲害的參賽者試著寫出非常不可讀的 C 程式碼，但結果往往是出人意料的。

壞消息是如果你是個完全的初學者，那麼全部的 C 程式碼對你而言可能都是霧裡看花。不過好消息是，不用擔心，這個狀況很快就會改善了！

我們在這裡會努力將您從完全不懂、完全感到困惑的情況，引導到純 C 語言程式設計才能帶給你的幸福感。
