带农历万年历C语言程序,c语言万年历程序代码

下面是一个带有农历和万年历功能的 C 语言程序代码示例：

#include <stdio.h>
#include <stdlib.h>

int get_weekday(int year, int month, int day) {
    if (month == 1 || month == 2) {
        month += 12;
        year--;
    }
    int c = year / 100;
    year %= 100;
    int week = year + year / 4 + c / 4 - 2 * c + 13 * (month + 1) / 5 + day - 1;
    week = (week % 7 + 7) % 7;
    return week;
}

int is_leap_year(int year) {
    return year % 4 == 0 && year % 100 != 0 || year % 400 == 0;
}

int get_month_days(int year, int month) {
    int days[] = {31, 28 + is_leap_year(year), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
    return days[month - 1];
}

void print_calendar(int year, int month) {
    printf("      %d 年 %d 月\n", year, month);
    printf("日 一 二 三 四 五 六\n");
    int weekday = get_weekday(year, month, 1);
    for (int i = 0; i < weekday; i++) {
        printf("   ");
    }
    int month_days = get_month_days(year, month);
    for (int i = 1; i <= month_days; i++) {
        printf("%2d ", i);
        if ((i + weekday) % 7 == 0) {
            printf("\n");
        }
    }
    if ((month_days + weekday) % 7 != 0) {
        printf("\n");
    }
}

void print_lunar_calendar(int year, int month, int day) {
    char *lunar_year[] = {
        "零", "一", "二", "三", "四", "五", "六", "七", "八", "九", "十", "十一", "十二",
        "十三", "十四", "十五", "十六", "十七", "十八", "十九", "二十"
    };
    char *lunar_month[] = {
        "正", "二", "三", "四", "五", "六", "七", "八", "九", "十", "冬", "腊"
    };
    char *lunar_day[] = {
        "初", "十", "廿", "三十"
    };
    int lunar_month_days[] = {
        29, 30, 29, 30, 29, 30, 29, 30, 29, 30, 29, 29
    };
    int lunar_year_days = 0;
    for (int i = 1901; i < year; i++) {
        lunar_year_days += is_leap_year(i) ? 366 : 365;
    }
    for (int i = 1; i < month; i++) {
        lunar_year_days += lunar_month_days[i - 1];
    }
    lunar_year_days += day - 1;
    int lunar_year_months[] = {0, 12};
    int lunar_year_days_sum[] = {0, 383};
    int lunar_month_days_sum = 0;
    for (int i = 0; i < 12; i++) {
        lunar_month_days_sum += lunar_month_days[i];
        if (lunar_year_days_sum[0] + lunar_month_days_sum <= lunar_year_days) {
            lunar_year_months[0]++;
            lunar_year_days_sum[0] += lunar_month_days_sum;
        }
        if (lunar_year_days_sum[1] + lunar_month_days_sum <= lunar_year_days) {
            lunar_year_months[1]++;
            lunar_year_days_sum[1] += lunar_month_days_sum;
        }
    }
    int lunar_month = lunar_year_months[1] == 12 ? 1 : lunar_year_months[1] + 1;
    int lunar_day = lunar_year_days - lunar_year_days_sum[1] + 1;
    printf("农历：%s%s年%s月%s%s\n", lunar_year[year / 1000], lunar_year[year % 1000 / 100], lunar_month[lunar_month], lunar_day[lunar_day / 10], lunar_day[lunar_day % 10]);
}

int main() {
    int year, month, day;
    printf("请输入年份：");
    scanf("%d", &year);
    printf("请输入月份：");
    scanf("%d", &month);
    printf("请输入日期：");
    scanf("%d", &day);
    print_calendar(year, month);
    print_lunar_calendar(year, month, day);
    return 0;
}

这个程序可以通过输入年份、月份和日期来打印出对应的公历和农历日历。其中，`get_weekday()` 函数用于计算某一天是星期几，`is_leap_year()` 函数用于判断某一年是否为闰年，`get_month_days()` 函数用于获取某一年某一月的天数，`print_calendar()` 函数用于打印公历日历，`print_lunar_calendar()` 函数用于打印农历日历。
