 根据其内容可将其细分一下：

基本的数据类型关键字：void, int, char, float, double, bool

类型修饰关键字：long, short, singed, unsigned 

布尔型字面值：true, false

非常重要的变量声明修饰符：const, inline

存储类别关键字：auto, static, extern, , register

控制结构关键字：for, while, if, else, do

switch语句关键字：switch, case, default

路径跳转关键字：break, continue, return, goto

动态创建变量关键字：new, delete

长度运算符：sizeof

复合类型关键字：class, struct, enum, union, typedef

与类成员相关关键字：this, friend, virtual, mutable, explicit, operator 

派生类继承方式：private, protected, public

模板：template, typename

命名空间：namespace, using

异常处理：catch, throw, try,

各种操作符的替代名：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

在cena中time 是保留的 如果拿 time 做变量名 会 无法编译
