int main()
{
    int year, month, day, overAllDays = 0;// 年 月 日 总天数
    scanf("%d/%d/%d", &year, &month, &day);
    int daysOfMonth[12] = { 31,28,31,30,31,30,31,31,30,31,30,31 };// 非闰年各月天数
    if (year % 400 == 0 || (year % 4 == 0 && year % 100 != 0)) {
        daysOfMonth[1] = 29; // 判断闰年
    }
    for (int i = 0; i < month - 1; i++)
    {
        overAllDays += daysOfMonth[i];
    }
    overAllDays += day;
    printf("%d", overAllDays);
    return 0;
