基本解釋空指針英漢例句雙語例句NULL is defined simply as a null pointer (0) because the null pointer is invalid as a pointer anyway.NULL 被簡單地定義爲(wèi)一個空指針(0),因爲(wèi)無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.它在兩個域中都放置一個空指針來表示空鏈表,而不是爲(wèi)空鏈表定義一個單獨(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,衹有一個空指針。null pointer更多例句詞組短語短語null -pointer dereference 空指針引用;個空指針引用Null pointer assignment 無傚的斷點(diǎn)分配;無傚的斷點(diǎn)分派;無傚的續(xù)點(diǎn)分派;無傚的續(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;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)
