如何在C/C++中使用枚舉？

枚舉是C語言中的使用者定義資料型別。它用於給整數常數賦予名稱，使程式易於閱讀和維護。關鍵字“enum”用於聲明一個枚舉。

以下是C語言中枚舉的語法：

enum enum_name{const1, const2, ....... };

The enum keyword is also used to define the variables of enum type. There are two ways to define the variables of enum type as follows .

enum week{sunday, monday, tuesday, wednesday, thursday, friday, saturday};
enum week day;

Here is an example of enum in C language,

Example

#include<stdio.h>
enum week{Mon=10, Tue, Wed, Thur, Fri=10, Sat=16, Sun};
enum day{Mond, Tues, Wedn, Thurs, Frid=18, Satu=11, Sund};
int main() {
   printf("The value of enum week: %d\t%d\t%d\t%d\t%d\t%d\t%d\n\n",Mon , Tue, Wed, Thur, Fri, Sat,    Sun);
   printf("The default value of enum day: %d\t%d\t%d\t%d\t%d\t%d\t%d",Mond , Tues, Wedn, Thurs, Frid,    Satu, Sund);
   return 0;
}

輸出

The value of enum week: 10111213101617
The default value of enum day: 0123181112
