关于C的问题，如何解决？

#include
int main()
{
    int month;
    printf("please enter a month\n");
    scanf_s("%d", &month);
    switch (month)
    {
    case 3:
    case 4:
    case 5:
        printf("%d is spring\n");
        break;
    case 6:
    case 7:
    case 8:
        printf("%d is summer\n");
        break;
    case 9:
    case 10:
    case 11:
        printf("%d is autumn\n");
        break;
    case 12:
    case 1:
    case 2:
        printf("%d is winter\n");
        break;
    default:
        printf("error\n");

    }
    return 0;
}

这怎么处理啊？

你的%d对应的要输出的数呢？？printf("%d is spring\n", month);

printf("%d is spring\n");
改为
printf("%d is spring\n",month);
其它都一样要改
