 printf("%d\n",(*st).elem[]);这里报错，我想打印出上面的数组
 printf("\n");
 printf("which you foud: ");
 scanf("%d",&s);
 i=Search_Bin(st,s);
 if(i)
   printf("%d this is%d\n",st.elem[i].key,i);
 else
   printf("no\n");
 Destroy(&st);
 }

将那句话改为：
for(i=1;i<=st.length;i++)   printf("%d ",st.elem[i]);
还有：将它上面的函数调用Creat_seq(&st,r,N);改为Creat_Seq(&st,r,N);(你忘了大写了）.

谢谢 了阿
