测试第三片，我贴C的代码！

#include<stdio.h>
void main()
{
   enum fruit {apple,orange,banana,pineapple,pear};
   enum fruit x,y,z,temp;
   int i=0,loop;
   for(x=apple;x<=pear;x++)
      for(y=apple;y<=pear;y++)
    if(x!=y)
    {
     for(z=apple;z<=pear;z++)
     {
      if((x!=z)&&(y!=z))
      {
            i++;
      printf("CASE %d:",i);
                     for(loop=1;loop<=3;loop++)
      {
       switch(loop)
       {
          case 1:temp=x;break;
                            case 2:temp=y;break;
       case 3:temp=z;break;
       }
       switch(temp)
       {
                   case 1:printf("apple ");break;
                   case 2:printf("orange ");break;
                   case 3:printf("banana ");break;
                   case 4:printf("pineapple ");break;
          case 5:printf("pear ");break;
       }
       loop++;
      }
      printf("n");
      }
    }
}
