null pointer：空指針

感覺我們的討論把 空指針(null pointer) 和 NULL 宏定義混在一起了. 有時(shí)把NULL當(dāng)作概念用,有時(shí)把NULL當(dāng)作宏定義用.計(jì)算機(jī)說白了就是數(shù)學(xué). NULL只不過是數(shù)學(xué)概念的計(jì)算機(jī)表示(represent)0 和 空(NULL) 在概念上是兩碼事

null pointer：空指標(biāo)

=== 空指標(biāo)(null pointer)問題 ===不要使用靜態(tài)類別(class-static)變數(shù),尤其是函式庫和可裝入模塊. 即使在應(yīng)用程式也是不鼓勵(lì)使用. 靜態(tài)物件會(huì)導(dǎo)致很多問題,如由於未定義建構(gòu)或解構(gòu)的次序,難以對 crashes 進(jìn)行除錯(cuò).
