3. 萬年歷C語言
// 萬年歷.cpp : Defines the entry point for the console application.
// 顯示1900年以後任何年份的日歷,日歷以月份順序排列,每月以星期順序排列。
//採用一般日歷計算方法,先給出一般年份的每月天數,如果是閏年,第二個月天數為29,再計算出制定年份的1月1日是星期幾,然後根據這些數據
//計算出全年日歷,邊計算邊顯示。
//函數leap()判定是否閏年
//函數week()計算year年份的1月1日是星期幾。計算方法是,已知1900年1月1日是星期一,先計算從1900年到year年份的前一年一共有多少(s)天,
//則(s+1)%7為年份year的1月1日的星期號。
#include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <string>
using namespace std;
static char *week0=" SUN MON TUE WED SUR FRI SAT"; //指針形式定義一個字元串,或者是week0[36]
int leap(int year)
{
if((year%4==0 && year%100!=0)|| year%400==0)
return 1;
else return 0;
}
int week(int year)
{
int i,w;
int s=0;
for(i=1900;i<year;i++)
{
if(leap(i))
s+=366;
else s+=365; //計算從1900年到year年的天數
}
w=(s+1)%7;
return w;
}
void main()
{
int month[12]={31,28,31,30,31,30,31,31,30,31,30,31};
int i,j,k;
int year;
int w;
do
{
cout<<"輸入年份:";
cin>>year;
}while(year<=1900);
w=week(year);
if(leap(year))
month[1]=29;
for(i=0;i<12;i++)
{
for(k=0;k<35;k++)
cout<<"_"; //輸出一條橫線
cout<<endl;
cout<<setw(20)<<i+1<<"月"<<endl;
cout<<endl;
cout<<week0<<endl;
for(k=0;k<w;k++)
cout<<" "; //輸出若干空格
for(j=1;j<=month[i];j++)
{
if((j+w)%7==1) //遇到星期日時,換一行輸出
cout<<endl;
cout<<setw(5)<<j;
}
cout<<endl;
for(k=0;k<35;k++)
cout<<"_"; //輸出一條橫線
cout<<endl;
w=(w+month[i])%7; //計算下個月1號是星期幾
}
cout<<endl;
system("pause");
}
4. 用C語言怎麼編寫萬年歷
C語言編寫萬年歷的源代碼如下:
#include <stdio.h>
int week(int y,int m,int d);
int main()
{
char wk[7][3] = {{"天"},{"一"},{"二"},{"三"},{"四"},{"五"},{"六"}};
int year, month, day, w;
scanf("%d %d %d", &year, &month, &day);
w = week(year, month, day);
printf("%d年%d月%d日 星期%s", year, month, day, wk[w]);
}
int week(int y,int m,int d)
{
static int r[13]={0,0,3,3,6,1,4,6,2,5,0,3,5};
int c,w;
y %= 400;
if ((y==0||y%4==0&&y%100!=0)&&m<3)
c = 5;
else
c = 6;
w = (y+y/4-y/100+r[m]+d+c)%7;
return w;
}
(4)c語言萬年歷節假日擴展閱讀
電子時鍾C語言版的源代碼如下:
#include<stdio.h>
#include<time.h>
#include<string.h>
int main()
{
char str[50];
time_t t;
struct tm *nt;
while(1)
{
system("cls");//清屏函數
t=time(NULL);
nt=localtime(&t);
strftime(str,50,"%Y-%m-%d %H:%M:%S 「,nt);
printf("現在時刻:%s ",str);
}
getch();
return 0;
}
5. 用C語言怎麼編寫這個萬年歷
核心演算法:星期(0~6)=(年份系數+月份系數+日期)%7;
其中,年份系數我以2007年做參照,已知2007年,年份系數是0,往前往後分別是遞減和遞增。增減規律:非閏年為±1,閏年1~2月-2或+1,閏年3~12月+2或者-1。
其中,12個月份系數對應:0,3,3,6,1,4,6,2,5,0,3,5。
根據以上規律,只要利用循環,就可以的到對應系數和星期。
日歷實現翻頁功能,按鍵盤左右方向鍵可以翻譯查看當年其他月份,按向上方向鍵可以返回菜單。
下面是代碼:
#include <stdio.h>
#include <malloc.h>
#include <string.h>
#include <conio.h>
#include <math.h>
#include <time.h>
#define XY 2007
#define X07 0//以2007年年系數0做參照
int isLeapYear(int year);//判斷是否是閏年,是返回1,否返回0
int addyx(int yx,int n);//年系數自增,0~6,n:自增的跨度,返回自增後的年系數
int getYX(int year,int month);//獲得年系數0~6
int getMX(int month);//獲得月系數
int getWeek(int yx,int mx,int day);//通過年月系數(yx:年系數;mx:月系數)及日期獲取星期
char *getStrWeek(int yx,int mx,int day);//通過年月系數(yx:年系數;mx:月系數)及日期獲取星期對應的中文字元串
int getMaxDay(int year,int month);//通過年月獲取當月最大天數
void prCalendar(int year,int month);//列印日歷
int showMeun();//列印主菜單
