我正在尝试用c语言使用switch语句创建时间转换器，但它不起作用。

#include <stdio.h>

int main() {
    int time;
    printf("请输入一个时间（0-23）：");
    scanf("%d", &time);

    switch (time) {
        case 0:
            printf("凌晨\n");
            break;
        case 1:
        case 2:
        case 3:
            printf("深夜\n");
            break;
        case 4:
        case 5:
            printf("黎明\n");
            break;
        case 6:
        case 7:
        case 8:
        case 9:
        case 10:
            printf("早上\n");
            break;
        case 11:
        case 12:
            printf("中午\n");
            break;
        case 13:
        case 14:
        case 15:
        case 16:
            printf("下午\n");
            break;
        case 17:
        case 18:
        case 19:
            printf("傍晚\n");
            break;
        case 20:
        case 21:
        case 22:
        case 23:
            printf("晚上\n");
            break;
        default:
            printf("请输入有效的时间（0-23）！\n");
            break;
    }

    return 0;
}
