    char *p = NULL;
    scanf("%d", &n);
    s = getmonth(n);
    if (s == NULL)
        printf("wrong input!\n");
    else
        printf("%s\n", s);
    return 0;
}
char *getmonth(int n)
{
    //指针数组
    char *month[13] = {"0", "January", "February", "March", "April", "May",
                          "June", "July", "August", "September", "October", "November", "December"};
    if (n > 0 && n < 13)
    {
        return month[n];
    }
