代碼將永遠不會執行C

-3

我有這個問題，它說，如果（knightATKC == 2 & & knightATKC == 4）我說，代碼將永遠不會執行。它將無法正常工作。如果有人知道如何解決這個問題，那會很好。不要擔心你可能會看到的未使用的變量，我將盡快使用它，但現在我不知道如何修復代碼將永遠不會執行。對不起，我可憐的英語：/代碼將永遠不會執行C

如果你想要執行代碼，不要求一個永遠不會成立的條件！ –

@DiegoBasch有時開發人員會犯簡單的編碼錯誤。有時候會有混亂。有時候我們會給這個人帶來懷疑的好處。 – zaph

你的問題是不言自明的。 knightATKC == 2 && knightATKC == 4表示knightATKC同時是2和4，這是不可能的。也許你的意思是||（布爾或）而不是&&（布爾和）？

壞聲明：

if (knightATKC == 2 && knightATKC == 4)

這整個如果因爲&&運營商「和」聲明絕不是真實的，因此第一比較和第二都必須是真實的。但是，如果knightATKC等於2那麼knightATKC不能等於4。

也許你想要的是「或」

if (knightATKC == 2 || knightATKC == 4)

如果以上任何一種情況。
