c++中關(guān)鍵字的分類

【專家解說】：C++中共有74個關(guān)鍵字 保留字。 and and_eq asm auto bitand bitor bool break case catch char class compl const const_cast continue default delete do double dynamic_cast else enum explicit export extern false float for friend goto if inline int long mutable namespace new not not_eq operator or or_eq private protected public register reinterpret_cast return short signed struct sizeof static static_cast throw switch template this typeid true try typedef using typename union unsigned virtual void volatile wchar_t while xor xor_eq 根據(jù)其內(nèi)容可將其細分一下： 基本的數(shù)據(jù)類型關(guān)鍵字：void, int, char, float, double, bool 類型修飾關(guān)鍵字：long, short, singed, unsigned 布爾型字面值：true, false 非常重要的變量聲明修飾符：const, inline 存儲類別關(guān)鍵字：auto, static, extern, , register 控制結(jié)構(gòu)關(guān)鍵字：for, while, if, else, do switch語句關(guān)鍵字：switch, case, default 路徑跳轉(zhuǎn)關(guān)鍵字：break, continue, return, goto 動態(tài)創(chuàng)建變量關(guān)鍵字：new, delete 長度運算符：sizeof 復(fù)合類型關(guān)鍵字：class, struct, enum, union, typedef 與類成員相關(guān)關(guān)鍵字：this, friend, virtual, mutable, explicit, operator 派生類繼承方式：private, protected, public 模板：template, typename 命名空間：namespace, using 異常處理：catch, throw, try, 各種操作符的替代名：and, and_eq, bitand, bitor, compl, not, not_eq, or, or_eq, xor, xor_eq 其他不常用的：asm, export, typeid, volatile
