用c语言编写下列程序:8、输入一个星期的序号，输出英文的星期几。

#include <stdio.h>

int main() {
    int day;
    printf("请输入星期的序号：");
    scanf("%d", &day);
    switch (day) {
        case 1:
            printf("Monday");
            break;
        case 2:
            printf("Tuesday");
            break;
        case 3:
            printf("Wednesday");
            break;
        case 4:
            printf("Thursday");
            break;
        case 5:
            printf("Friday");
            break;
        case 6:
            printf("Saturday");
            break;
        case 7:
            printf("Sunday");
            break;
        default:
            printf("输入有误，请输入1-7之间的整数。");
            break;
    }
    return 0;
}
