C语言课程设计实验报告(万年历)

C语言课程设计一、题目及功能描述题目：万年历的设计利用C语言设计出万年历，使其实现如下要求1、输入一个年份，在屏幕上输出该年的年历〔包括每月的天数和所对应的星期几〕，并且在每月的左上角或右上角打印出相应的年份和月份，要求输出界面尽可能整齐、美观，符合年历显示标准。假定输入的年份在1-9999年之间。2、输入年月，输出该月的月历。3、输入年月日，输出距今天还有多少天，是星期几，是否是公历节日。：4、指定键盘的某些键，用于控制变换不同年、月、日的显示。即：当前假设正在显示2023年的年历，按下键盘“←〞方向键后，年历变为2023年的。二、使用的所有变量的说明变量说明：〔以下均为整型变量〕year表示年份的变量month表示月份的变量day表示日期的变量select表示菜单项选择择的变量i表示月份的变量j表示一个月中的某一天的变量sum判断某天是一年中的第几天的变量number判断某天离公元1年1月1日还有几天的变量a[]表示每月天数的数组变量year1系统时间年份的变量month1系统时间月份的变量day1系统时间日期的变量三、程序清单及其说明#include"time.h"/*包含的头文件*/#include"stdio.h"#include"math.h"#include"windows.h"#include"conio.h"#defineKEYNUMUp0x48/*宏定义*/#defineKEYNUMDown0x50#defineKEYNUMLeft0x4b#defineKEYNUMRight0x4d#defineKEYNUMPageUp0x49#defineKEYNUMPageDown0x51inteachyeartotal(intyear,intmonth,intday);/*函数声明*/intcounterdays(intyear,intmonth,intday);intnowtime(intyear,intmonth,intday);intweek(intyear,intmonth,intday);intmaxDay(intyear,intmonth);intisleap(intyear);voidwhatweek(intyear,intmonth,intday);voiddisplay(intyear,intmonth);voiddisplay2(intyear,intmonth);voiddisplay3(intyear,intmonth,intday);voidsetDay1(intyear,intmonth,intday);voidsetDay2(intyear,intmonth,intday);voidsetDay3(intyear,intmonth,intday);voidjieri(intmonth,intday);voiddisplay1(intyear);voidgetmenu();voidmain()/*主函数*/{intyear,month,day,select;while(1){getmenu();printf("请输入相应数字:");/*菜单项选择择*/scanf("%d",&select);system("cls");switch(select){case1:/*中选择为1时显示年历*/printf("年历显示：输入年〔如2023〕:");scanf("%d",&year);if(year>0&&year<10000)/*显示年份从0-10000*/{
