关键字是C++中预先保留的单词(标识符)
在定义变量或者是常量的时候,不要用到关键字
C++的关键字参考如下
| asm | do | if | return | typedef |
| auto | double | inline | short | typeid |
| bool | dynamic_cast | int | signed | typename |
| break | else | long | sizeof | union |
| case | enum | mutable | static | unslgned |
| catch | explicit | namespace | static_cast | using |
| char | export | new | struct | virtual |
| class | extern | operator | switch | void |
| const | false | private | template | volatile |
| const_cast | fioat | protectecd | this | wchar_t |
| continue | for | public | throw | while |
| default | friend | regiter | true | |
| delete | goto | reinterpret_cast | try |
提示:在给变量或者变量起名的时候,不要用C++关键字,否则会产生歧义
