C ++中有多少个关键字？
在C++中总共有95个保留词。C++的保留字可以方便地放置到多个组中。在第一组中，我们将那些也存在于C编程语言中并已经被移植到C++中。一共有32个。
还有30个不在C中的保留字，因此对C ++来说是新的
当使用标准ASCII字符集时，有11个C++保留字不是必需的，但是它们被添加以提供一些C++操作符更可读的替代品，并且还便于用缺少C++所需字符的字符集编程。
这是所有这些保留字的列表：
| alignas (since C++11) | alignof (since C++11) | and |
| and_eq | asm | atomic_cancel (TM TS) |
| atomic_commit (TM TS) | atomic_noexcept (TM TS) | auto(1) |
| bitand | bitor | bool |
| break | case | catch |
| char | char16_t (since C++11) | char32_t (since C++11) |
| class(1) | compl | concept (since C++20) |
| const | constexpr (since C++11) | const_cast |
| continue | co_await (coroutines TS) | co_return (coroutines TS) |
| co_yield (coroutines TS) | decltype (since C++11) | default(1) |
| delete(1) | do | double |
| dynamic_cast | else | enum |
| explicit | export(1) | extern(1) |
| false | float | for |
| friend | goto | if |
| import (modules TS) | inline(1) | int |
| long | module (modules TS) | mutable(1) |
| namespace | new | noexcept (since C++11) |
| not | not_eq | nullptr (since C++11) |
| operator | or | or_eq |
| private | protected | public |
| register(2) | reinterpret_cast | requires (since C++20) |
| return | short | signed |
| sizeof(1) | static | static_assert (since C++11) |
| static_cast | struct(1) | switch |
| synchronized (TM TS) | template | this |
