哪里，呵呵。

给你这个自己改去

你QQ?我加你详谈。。。。。。。。。。。。。

还是昨天那个程序 ，我自己写的，不过还有问题 ，大家帮我改改。

说出来 很简单 问题是 作出来 不是 那么 简单吧 反正我是不会 刚学 新手路过

有计算日期的公式，用那个公式就很容易了

/* Note:Your choice is C IDE */
#include "stdio.h"
void main()
{   
    int day,month,year,sum,leap=0,a=0,b=0,c=0;
    printf("please input year,month,day:");
    scanf("%d,%d,%d",&year,&month,&day);
    switch(month)
    {   
        case 1:sum=0 ;break;
        case 2:sum=31 ;break;
        case 3:sum=59 ;break;
        case 4:sum=90 ;break;
        case 5:sum=120 ;break;
        case 6:sum=151 ;break;
        case 7:sum=181 ;break;
        case 8:sum=212 ;break;
        case 9:sum=243 ;break;
        case 10:sum=273 ;break;
        case 11:sum=304 ;break;
        case 12:sum=334 ;break;
        default:printf("data error");break;
         
         
    }
    sum=sum+day;
    if(year%400==0||(year%4==0&&year%100!=0))
      leap=1;
    else
      leap=0;
    if(leap==1&&month>2)
      sum++;
        a=year-2009-b;
        b=c/4;
        c=year-2008;
        sum=sum+a*365+b*366;
        printf("%d",sum%7+3);
}
 
 
     

指点指点 我不会  谢谢

大家看看这个程序有啥问题 修改修改  谢谢了

你说废话啊  啥公式
