关键字是C++中预先保留的单词(标识符)
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,不哟啊用C++关键字,否则会产生歧义
