有多个输入测试用例，每一个用例一行，是一个0～9的整数，输入为0时则结束。屏幕显示如下：
样例输入                             样例输出
 2                                  case  1:
                                       1
                                      222
3
                                    case  2:
                                       1
                                      222
                                 33333
0
end

#include<stdio.h>
int main()
{
    int n;
    scanf("%d", &n);
    int i;
    while (n)
    {
        for (i = 1; i <= n; i++)
        {
            int j = i;
            while (j)
            {
                printf("%d", i);
                j--;
            }
            printf("\n");
        }
      scanf("%d", &n);
    }
   return 0;
}

这个意思？

不是你这个意思。

#include<stdio.h>
int main()
{
    int n,i;
    scanf("%d", &n);
    if(n==0)
    printf("end\n");
    else
    {
    printf("case %d:", n-1);
    printf("\n");
    while (n)
    {
       for (i = 1; i <= n; i++)
        {
            int j = 2*i-1;
            
            while (j)
            {
                printf("%d", i);
                j--;
            }
            printf("\n");
        }
      scanf("%d", &n);
      if(n==0)
        printf("end\n");
    }
   }
   return 0;
}
