本文实例为大家分享了C语言实现万年历程序，供大家参考，具体内容如下
#include <stdio.h>
int year(int y)
{
if ((y%4==0) && (y%100!=0) || y%400==0)
return 366;
else
return 365;
}
int main()
{
int y;
int i,j,sum=0;
int begin,week;
int days[12]={31,28,31,30,31,30,31,31,30,31,30,31};
scanf("%d",&y);
for(i=1;i<y;i++)
sum+=year(i);
week=(sum+1)%7; //表示该年1月1日为星期几
if(year(y)==366)
days[1]=29;
printf("\n%d年日历如下：\n\n",y);
for(i=0;i<12;i++)
{
printf(" %d月 \n",i+1);
printf(" 7 1 2 3 4 5 6\n");
printf("=====================\n");
begin=1;
for(j=0;j<week;j++)
printf(" ");
while(begin<=days[i])
{
printf("%3d",begin);
begin++;
week=(week+1)%7;
if(week%7==0)
printf("\n");
}
printf("\n\n");
}
return 0;
}
