链表的查找和插入(c语言)

Link InsertList(Link Head,Link New,int Key)
{
Link Pointer;
Pointer = Head;

while(1)
{
if(Pointer == NULL)
{
New->Next = Head;
Head = New;
break;
}
if(Pointer->Number == Key)
{
New->Next = Pointer->Next;
Pointer->Next = New;
break;
}
Pointer = Pointer->Next;
}
return Head;
}

void FreeList(Link Head)
{
Link Pointer;

while(Head != NULL)
{
Pointer = Head;
Head = Head->Next;
free(Pointer);
}
}
-----------------------------------

int ListSearch(int Key,Link Head)
{
Link Pointer;

Pointer = Head;

while(Pointer != NULL)
{
SearchTime++;
if(Pointer->Number == Key)
{
printf("Data Number:%d/n",Pointer->Number);
printf("Data Total:%d/n",Pointer->Total);
return 1;
}
Pointer = Pointer->Next;
}
return 0;
