⑧ NDK学习之C语言枚举

//枚举

//枚举(列举所有的情况)，限定值的取值范围，保证取值的安全性

enum Day

5

{

 Monday,

7

 Tuesday,

8

 Wednesday,

9

 Thursday,

10

 Friday,

11

 Saturday,

12

 Sunday

13

};

​

15

void main() {

16

 enum Day d = Tuesday;

17

 printf("%#x,%d\n",&d,d);

18

 getchar();

19

}

也就是说  把这个值限定在范围内 

也能这么做

};

void main() {

 enum Day d = Tuesday;

15

 printf("%#x,%d\n",&d,d);

16

 getchar();

17

}
