我正在使用 ANSI C 在控制台应用程序中以传统格式实现一个简单的年历。日历必须以 3 x 4 个月的格式显示。到目前为止，我设法将所有月份显示在彼此下方，如下面的代码所示。任何帮助我如何解决标签部分？我尝试根据列将月份 [] 拆分为 3，例如一月、四月、七月和十月将是第一列，然后逐列工作，但我不知道这是否是最好的做法。 ..有什么帮助吗？

#include<stdio.h>

int main()
{
 int d,y,no_lp,n,i=1,j,month[]={0,31,28,31,30,31,30,31,31,30,31,30,31};

 printf("Enter year:");
 scanf("%d", &y);

 if (y%4==0)
 {month[2]=29;}

 no_lp= (27 + (42/5) + (y-1) + ((y-1)/4) - ((y-1)/100) + ((y-1)/400) + 1);
 d= no_lp%7;

 n=d;

 for(j=1;j<=12;j++)    
 {
  printf("\n\n       %s",monthname[j]);
  //printf ("\n\n%d",j);
  printf("\n Su Mo  Tu  We  Th  Fr  Sa\n");

  while(d--!=0)
    printf("    ");  //spaces for empty days

  while(i<=month[j])
  {
   if(i<10)
   {printf(" %d  ",i++);} //formating for dates with 2 digits

   else{printf("%d  ",i++);}//formatting for dates with 1 digit
   n++;

   if(n==7)        //if 7 is reached start new line
   {
    n=0;
    printf("\n");
   }
  }

  d=n;
  i=1;            //n will be the 1st day of next month
 }

 return(0);
}

你可以更换

   if(i<10)
   {printf(" %d  ",i++);} //formating for dates with 2 digits

   else{printf("%d  ",i++);}//formatting for dates with 1 digit

和

printf("%2d  ",i++);

为了打印 3 * 4，不要即时打印

存储这些值

char out[12][6][24];
          |  |  |
n months <-  |  -> string containing week in calendar (e.g 10 11 12 13 14 15 17)
             V
    Max weeks in a month

并打印

week 1 month 1 , week 1 month 2 ,  week 1 month 3
week 2 month 1 , week 2 month 2 ,  week 2 month 3
week 3 month 1 , week 3 month 2 ,  week 3 month 3
...
week 1 month 4 , week 1 month 5 ,  week 1 month 6
week 2 month 4 , week 2 month 5 ,  week 2 month 6
week 3 month 4 , week 3 month 5 ,  week 3 month 6
...
