linux c 枚举的使用

enum 枚举名 {
    枚举值1,
    枚举值2,
    ...
    枚举值n
};

#include <stdio.h>

// 定义一个表示星期的枚举类型
enum Weekday {
    MONDAY,
    TUESDAY,
    WEDNESDAY,
    THURSDAY,
    FRIDAY,
    SATURDAY,
    SUNDAY
};

int main() {
    // 声明一个枚举变量并赋值
    enum Weekday today = WEDNESDAY;

    // 使用switch语句处理枚举值
    switch(today) {
        case MONDAY:
            printf("Today is Monday.\n");
            break;
        case TUESDAY:
            printf("Today is Tuesday.\n");
            break;
        case WEDNESDAY:
            printf("Today is Wednesday.\n");
            break;
        case THURSDAY:
            printf("Today is Thursday.\n");
            break;
        case FRIDAY:
            printf("Today is Friday.\n");
            break;
        case SATURDAY:
            printf("Today is Saturday.\n");
            break;
        case SUNDAY:
            printf("Today is Sunday.\n");
            break;
        default:
            printf("Invalid day.\n");
            break;
    }

    return 0;
