连接两个链表

程序源代码:
#include "stdlib.h"
#include "stdio.h"
struct list
{ int data;
struct list *next;
};
typedef struct list node;
typedef node *link;
link delete_node(link pointer,link tmp)
{if (tmp==NULL) /*delete first node*/
 return pointer->next;
else
{ if(tmp->next->next==NULL)/*delete last node*/
  tmp->next=NULL;
 else /*delete the other node*/
  tmp->next=tmp->next->next;
 return pointer;
}
}
void selection_sort(link pointer,int num)
{ link tmp,btmp;
 int i,min;
 for(i=0;i  {
 tmp=pointer;
 min=tmp->data;
 btmp=NULL;
 while(tmp->next)
 { if(min>tmp->next->data)
 {min=tmp->next->data;
  btmp=tmp;
 }
 tmp=tmp->next;
 }
printf("\40: %d\n",min);
pointer=delete_node(pointer,btmp);
}
}
link create_list(int array[],int num)
{ link tmp1,tmp2,pointer;
int i;
pointer=(link)malloc(sizeof(node));
pointer->data=array[0];
tmp1=pointer;
for(i=1;i { tmp2=(link)malloc(sizeof(node));
 tmp2->next=NULL;
 tmp2->data=array[i];
 tmp1->next=tmp2;
 tmp1=tmp1->next;
}
return pointer;
}
link concatenate(link pointer1,link pointer2)
{ link tmp;
tmp=pointer1;
while(tmp->next)
 tmp=tmp->next;

return pointer1;
}
void main(void)
{ int arr1[]={3,12,8,9,11};
