In C programming, an enumeration type (also called enum) is a data type that consists of integral constants. To define enums, the enum keyword is used. enum flag {const1, const2, ..., constN}; By default, const1 is 0, const2 is 1 and so on. You can change default values of...

3、检查枚举变量 由于枚举类型enum封装了一组固定的变量,所以我们可以使用in操作来检查某个变量是否属于枚举类型,比如要检查tue是否属于week这个枚举类型: ``` if tue in week: print(tue belong to week else: print(tue is not a part of week ``` 4、使用枚举类型进行控制 枚举类型enum也可以用做语句中的...
