是C ++ 14添加新的关键字到C ++？ [英] Is C++14 adding new keywords to C++?

问题描述

C ++标准委员会倾向于不向该语言添加新关键字，但是使用C ++ 11不是这样。一些示例：

The C++ Standards Committee tends to shy away from adding new keywords to the language, yet with C++11 that was not the case. Some examples:

constexpr
decltype
thread_local
auto // New usage
noexcept
nullptr
static_assert
alignof
alignas

C ++ 14引入了新关键字吗

推荐答案

在N3936（C ++ 14）中：

Table 4 (Keywords) in N3936 (C++14):

alignas           continue          friend            register          true
alignof           decltype          goto              reinterpret_cast  try
asm               default           if                return            typedef
auto              delete            inline            short             typeid
bool              do                int               signed            typename
break             double            long              sizeof            union
case              dynamic_cast      mutable           static            unsigned
catch             else              namespace         static_assert     using
char              enum              new               static_cast       virtual
char16_t          explicit          noexcept          struct            void
char32_t          export            nullptr           switch            volatile
class             extern            operator          template          wchar_t
const             false             private           this              while
constexpr         float             protected         thread_local
const_cast        for               public            throw

表4在N3337（C ++ 11）中：

Table 4 in N3337 (C++11):

alignas           continue          friend            register          true
alignof           decltype          goto              reinterpret_cast  try
asm               default           if                return            typedef
auto              delete            inline            short             typeid
bool              do                int               signed            typename
break             double            long              sizeof            union
case              dynamic_cast      mutable           static            unsigned
catch             else              namespace         static_assert     using
char              enum              new               static_cast       virtual
char16_t          explicit          noexcept          struct            void
char32_t          export            nullptr           switch            volatile
class             extern            operator          template          wchar_t
const             false             private           this              while
constexpr         float             protected         thread_local
const_cast        for               public            throw

。

（ override 和 final 是具有特殊含义的标识符，并在表3中列出; 和等是替代表示...对于某些运算符和标点符号并且列在表5中。在C ++ 11和C ++ 14之间没有表改变。 ）

(override and final are "identifiers with special meaning" and are listed in Table 3; and etc. are "alternative representations...for certain operators and punctuators" and are listed in Table 5. Neither table changed between C++11 and C++14.)
