int main(){
    char *month[12]={"January","February","March","April","May" ,"June",
    "July" ,"August","September" ,"October","November","December"};
    int n;
    printf("input month:\n");
    scanf("%d",&n);
    if ((n<=12)&&(n>=1))
    printf("It is %s. \n", *(month+n-1));
    else
    printf("It is wrong. \n");
    return 0;
