计算C语言中两个日期的天数之差

struct Date {
    int year;
    int month;
    int day;
};

int getDayDifference(struct Date date1, struct Date date2) {
    // 计算两个日期的总天数差
    int totalDays1 = date1.year * 365 + date1.month * 30 + date1.day;
    int totalDays2 = date2.year * 365 + date2.month * 30 + date2.day;
    
    // 计算天数差
    int dayDifference = totalDays2 - totalDays1;
    
    return dayDifference;
}

int main() {
    struct Date date1 = {2022, 1, 1};
    struct Date date2 = {2022, 12, 31};
    
    int difference = getDayDifference(date1, date2);
    
    printf("两个日期的天数差为：%d\n", difference);
    
    return 0;
}
