C语言万年历代码

C语言万年历代码

题目：年历显示。

功能要求：（1）输入一个年份，输出是在屏幕上显示该年的日历。

假定输入的年份在1940-2040年之间。

（2）输入年月，输出该月的日历。

（3）输入年月日，输出距今天还有多少天，星期几，是否是公历节日。

如下图：以下部分为代码：#include<stdio.h>#include<math.h>void part1(int x); //函数1~6为打印日历的函数void part2(int x);void part3(int x);void part4(int x);void part5(int x);void part6(int x);int weak(int x,int y); //计算1号对应的星期int weak2(int x,int y,int z);

c语言年月日输出格式

c语言年月日输出格式

在C语言中，可以使用`strftime`函数来格式化日期和时间。

以下是一个示例，展示如何将当前日期和时间以年月日的格式输出：
```c
#include <stdio.h>
#include <time.h>
int main() {
time_t rawtime;
struct tm * timeinfo;
time(&rawtime);
timeinfo = localtime(&rawtime);
printf("当前的本地时间和日期: %d-%02d-%02d\n", timeinfo->tm_year + 1900, timeinfo->tm_mon + 1, timeinfo->tm_mday);
return 0;
}
```
在这个例子中，我们首先获取当前时间（`time(&rawtime)`），然后将其转换为本地时间（`localtime(&rawtime)`）。

`structtm`结构体中
的`tm_year`，`tm_mon`和`tm_mday`字段分别代表年、月和日。

我们可以通过加1900来获取完整的年份（因为`tm_year`是从1900年开始计数的），通过加1来获取正确的月份（因为`tm_mon`是从0开始计数的）。

最后，我们使用`printf`函数来输出格式化的日期。

万年历C语言报告3

万年历C语言报告3

万年历C语言报告3万年历是一种常用的日历工具，可以显示任意年份的任意月份的日历，并且还能够根据用户的需求进行一定的调整。

通过这个项目的设计和实现，我更深入地了解了C语言的应用，并且提升了编程能力。

本次实现的万年历功能主要包括以下几个方面：1. 用户输入年份和月份，程序可以显示对应年份和月份的日历。

为了实现这个功能，我首先使用了C语言的输入函数 scanf 来获取用户的输入，然后使用了计算机中的日期计算方法和算法来推算出该月份的具体日期。

最后，我们使用C语言的输出函数 printf 来将日历以表格形式显示出来。

2.用户可以选择其中一天并输出该天的详细信息。

在实现这个功能时，我首先使用了结构体来存储日期的信息，包括年、月、日、星期等。

然后，当用户选择其中一天时，我根据输入的日期，查找并输出对应的详细信息，如星期几、是一年中的第几天等等。

3.用户可以选择不同的视图显示日历。

为了实现这个功能，我使用了C语言的条件判断语句来判断用户的选择，并且根据不同的选择来显示不同的视图。

用户可以选择显示整个月份的日历，也可以只显示当月的日期。

此外，为了增加程序的可读性和易用性，我还对程序进行了一些优化和改进：1.使用函数来提高代码的复用性。

我将一些常用的功能封装成函数，如计算2024年6月的天数、计算其中一天的星期几等等。

这样不仅可以减少代码的冗余，并且让代码更加易读和易于维护。

2.添加错误处理机制。

用户输入的年份和月份可能会不符合规定范围，为了避免程序出错，我对用户的输入进行了检查，并在输入错误时进行了相应的提示。

这样可以增加程序的稳定性和可靠性。

3.增加程序的交互性。

用户可以通过菜单选择不同的功能和视图，并根据提示进行操作。

这样可以提高用户的使用体验和程序的易用性。

通过完成这个万年历项目，我不仅学习到了C语言的应用，还锻炼了自己的编程能力。

在这个过程中，我掌握了C语言的输入输出函数、条件判断语句、循环语句等基本语法，并熟悉了C语言的常用函数和相关算法。

c语言实现一个简单日历

c语言实现一个简单日历

c语⾔实现⼀个简单⽇历满⾜三个需求:1．输⼊⼀个年份，输出是在屏幕上显⽰该年的⽇历。

假定输⼊的年份在1940-2040年之间。

2．输⼊年⽉，输出该⽉的⽇历。

3．输⼊年⽉⽇，输出距今天还有多少天，星期⼏，是否是公历节⽇。

万年历代码c语言

万年历代码c语言万年历是一种实用的日历工具，它可以根据年、月、日来显示当天的日期信息，并可以切换到其他日期来查询对应的日期信息。

在编写万年历的代码时，我们需要考虑输入的年份是否为闰年、每个月的天数、以及每个月第一天是星期几等等。

以下是一份使用C语言编写万年历的参考代码：```c#include <stdio.h>// 判断是否为闰年int isLeapYear(int year) {return (year % 4 == 0 && year % 100 != 0) || (year % 400 == 0); }// 获取某年某月的天数int getMonthDays(int year, int month) {int days[] = {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};if (month == 2 && isLeapYear(year)) {return 29;}return days[month - 1];}// 获取某年某月第一天是星期几int getFirstDayOfWeek(int year, int month) {int day = 1;for (int i = 1800; i < year; i++) {if (isLeapYear(i)) {day = (day + 366) % 7;} else {day = (day + 365) % 7;}}for (int i = 1; i < month; i++) {day = (day + getMonthDays(year, i)) % 7;}return day;}int main() {int year, month;printf("请输入年份：");scanf("%d", &year);printf("请输入月份：");scanf("%d", &month);// 判断输入是否合法if (year < 1800 || month < 1 || month > 12) {printf("输入的年份或月份不合法！\n");return 0;}// 获取某年某月的天数和第一天是星期几int days = getMonthDays(year, month);int firstDayOfWeek = getFirstDayOfWeek(year, month); // 打印万年历printf("日一二三四五六\n");for (int i = 0; i < firstDayOfWeek; i++) {printf(" ");}for (int i = 1; i <= days; i++) {printf("%2d ", i);if ((firstDayOfWeek + i) % 7 == 0) {printf("\n");}}printf("\n");return 0;}```以上代码实现了一个简单的万年历功能，在控制台输出给定年份和月份的月历。

C语言打印某一年中某月的日历

C语言打印某一年中某月的日历

C语⾔打印某⼀年中某⽉的⽇历在做学校作业发现的⼀道不错的练⼿题⽬，记录下来⽅便复习⼤致思路：①判断输⼊的年份是否闰年；②计算输⼊⽉份的第⼀天是该年的第⼏天；③计算输⼊⽉份的第⼀天是星期⼏；④输出。

结合代码使⽤：#define _CRT_SECURE_NO_WARNINGS 1#include <stdio.h>int main(){int arr1[] = { 0,31,28,31,30,31,30,31,31,30,31,30,31 };int i = 0;int year = 0;int month = 0;int days = 0;int week = 0;//判断第⼀天周⼏scanf("%d%d", &year, &month);if((year % 4 == 0 && year % 100 != 0)||(year % 400 == 0))//判断是否是闰年{arr1[2] = 29;//闰年2⽉29天}for (i = 0; i < month; i++){days += arr1[i];//计算该⽉第⼀天是该年多少天}days++;//该⽉第⼀天，还要把这⼀天算上//套⽤计算星期⼏的公式week = (year - 1 + (year - 1) / 4 - (year - 1) / 100 + (year - 1) / 400 + days) % 7;printf(" ⽇⼀⼆三四五六\n");//表头int arr2[50] = {0};for (i = 0; i < week; i++){printf(" ");//整型数组不能存放空格，因此直接把空格打印出来}arr2[week] = 1;for (i = week + 1; i <= arr1[month]+week-1; i++)//把输⼊⽉份的每⼀天放到数组中{arr2[i] = arr2[i-1]+1;}int count = 0;//记录已打印⼏个数据，打印7个数据就换⾏i = week;int flag = 1;//⽤于记录是否为第⼀⾏，第⼀⾏不能⽤count计数⽅式换⾏while (i<=arr1[month]+week-1)//把该⽉所有天数都打印出来{if (flag <= 7-week){printf("%3d", arr2[i]);if (flag == 7 - week)//打印够数据后换⾏printf("\n");flag++;}else{printf("%3d", arr2[i]);count++;if (count == 7){count = 0;printf("\n");}}i++;}return 0;}实现结果：以上所述是⼩编给⼤家介绍的C语⾔打印某⼀年中某⽉的⽇历，希望对⼤家有所帮助。
