#include "stdio.h"
void main( )
{
  long a,b,c,d,e,x;
  printf("请输入一个五位或五位以下的数:");
  scanf("%ld",&x);
  a=x/10000;/*分解出万位*/          /*或a=x/10000%10
  b=x%10000/1000;/*分解出千位*/　　/*或b=x/1000%10
  c=x%1000/100;/*分解出百位*/      /*或c=x/100%10
  d=x%100/10;/*分解出十位*/        /*或d=x/10%10
  e=x%10;/*分解出个位*/            
  if (a!=0) printf("there are 5, %d%d%d%d%d\n",e,d,c,b,a);
  else if (b!=0) printf("there are 4, %d%d%d%d\n",e,d,c,b);
    else if (c!=0) printf(" there are 3,%d%d%d\n",e,d,c);
      else if (d!=0) printf("there are 2, %d%d\n",e,d);
        else if  (e!=0) printf(" there are 1,%d\n",e);
}
最后一句代码为什么用else(e!=0)不行呢，若用else(e!=0)调试时就提示出错，为什么呢？
