常見(jiàn)例句雙語(yǔ)例句Similar to an undefined external error, except that the reference is via metadata.與未定義的外部錯(cuò)誤類(lèi)似，不同的是引用是通過(guò)元數(shù)據(jù)。They hold only one piece of data: a string, a number, the undefined value, a reference to another variable.它衹保存一段數(shù)據(jù)：一個(gè)字符串、一個(gè)數(shù)字、未定義的值以及對(duì)另一個(gè)變…Note that had we declared the reference i without the const qualifier, the function f() could have modified its argument, thereby causing undefined behavior.注意我們沒(méi)有將i聲明爲(wèi)靜態(tài)類(lèi)型，但是函數(shù)f仍有可能脩改它的這個(gè)蓡數(shù)，這將引起異常。原聲例句Undefined reference, what was the solution last time?未定義的引用，上次我們是怎麼解決的呢？哈彿公開(kāi)課 - 計(jì)算機(jī)科學(xué)課程節(jié)選 返回 undefined reference
