C enum 关键字

❮ C 关键字


示例

创建一个枚举类型

enum Level {
  LOW,
  MEDIUM,
  HIGH
};

int main() {
  // 创建一个枚举变量并为其赋值
  enum Level myVar = MEDIUM;

  // 打印枚举变量
  printf("%d", myVar);

  return 0;
}
自己试试 »

定义和用法

The enum 关键字声明一个枚举,它是一种特殊的数据类型,表示一组常量(不可变值)。

要创建枚举,请使用 enum 关键字,后跟枚举的名称,并用逗号分隔枚举项。

注意:默认情况下,第一个枚举项的值为 0,第二个值为 1,依此类推。

枚举充当变量的数据类型。该类型的变量只能包含枚举中指定的那些值。
