求打出求打出某年某月月历，要区分闰年。
急，谢谢了！！！

#include <stdio.h>

int JgYr(int yr)
{
 if (yr%4==0&&yr%100!=0&brvbar;&brvbar;yr%100==0&&yr%400==0)
 return 1;
 else
 return 0;
}

int CalWkd(int yr,int mth)
{
 int ds=0,i,rst,wkd;
 int mthd[13]={0,31,28,31,30,31,30,31,31,30,31,30,31};

不是我写的，你看看吧！

#include<stdio.h>
int a[2][12]={{31,28,31,30,31,30,31,31,30,31,30,31},{31,29,31,30,31,30,31,31,30,31,30,31}};
int year,month,weekday;
int rn(int y)
{
    if(y%4==0&&y%100!=0||y%400==0)
        return 1;
    else
        return 0;
}
void printfm(int m,int j)
{
    int i;
    printf("%d月  日  一  二  三  四  五  六\n",m);
    printf("  ");
    for(i=0;i<weekday;i++)
    {
        printf("  ");
    }
    for(i=1;i<=a[j][m-1];i++)
    {
        printf("%5d",i);
        weekday=(weekday+1)%7;
        if(weekday==0)printf("\n");
    }
}

void main()
{
    int j;
    printf("输入年份: ");
    scanf("%d",&year);
    weekday=year-1+(year-1)/4-(year-1)/100+(year-1)/400+1;
    weekday=weekday%7;
    j=rn(year);
    printf("\n");
    printf("%d\n",year);
    for(int i=1;i<=12;i++)
    {
        printfm(i,j);
        printf("\n");
    }
}
自己整理下输出的格式吧

谢谢，挺急的，我整理下看看

又是一个平时不注意积累的孩子！

呵呵~~~~~~
