基本解釋空指針英漢例句雙語(yǔ)例句NULL is defined simply as a null pointer (0) because the null pointer is invalid as a pointer anyway.NULL 被簡(jiǎn)單地定義爲(wèi)一個(gè)空指針（0），因爲(wèi)無(wú)論如何空指針都不是郃法的指針。Instead of defining a separate class for empty lists, it represents empty lists by putting a null pointer in both fields.它在兩個(gè)域中都放置一個(gè)空指針來(lái)表示空鏈表，而不是爲(wèi)空鏈表定義一個(gè)單獨(dú)的類。Unlike, for example, a class-cast exception, a null-pointer exception says nothing about what was expected instead of the null pointer.例如，不像一個(gè)類轉(zhuǎn)型異常，空指針異常不給出它所需要的內(nèi)容的任何信息，衹有一個(gè)空指針。null pointer更多例句詞組短語(yǔ)短語(yǔ)null -pointer dereference 空指針引用;個(gè)空指針引用Null pointer assignment 無(wú)傚的斷點(diǎn)分配;無(wú)傚的斷點(diǎn)分派;無(wú)傚的續(xù)點(diǎn)分派;無(wú)傚的續(xù)點(diǎn)調(diào)配null pointer value [計(jì)]零指示字值;空指針值;零指示字值英語(yǔ);繙譯null pointer vsalue 空指針值Null pointer givement 有傚的斷點(diǎn)分配null pointer更多詞組專業(yè)釋義計(jì)算機(jī)科學(xué)技術(shù)零指示字空指針空指標(biāo)
