这是我的代码：

//5.插入一条成员记录，使原通讯录保持有序
    void insertYouXu(LinkList L,LinkList Elem)
    {
        LinkList p=L->next;
        while(p!=NULL && Elem->number >= p->number)
        {
            if(p->number==Elem->number)
            {
                printf("重复输入！！\n");
                return;
            }
            p=p->next;
        }
        if(p==NULL)//确定Elem的插入位置
        {
          p=prior(L,p);
          Elem->next=NULL;
          p->next=ELem;
        }
        else
        {
           p=prior(L,p);
           Elem->next=p->next;
           p->next=Elem;
        }
    }
下面是我的编译后生成的信息，新手实在不会改，请指教
\main.c|147|warning: implicit declaration of function 'prior'|
\main.c|147|warning: assignment makes pointer from integer without a cast|
\main.c|149|error: 'ELem' undeclared (first use in this function)|
\main.c|149|error: (Each undeclared identifier is reported only once|
\main.c|149|error: for each function it appears in.)|
\main.c|153|warning: assignment makes pointer from integer without a cast|

    p->next=ELem;
大小写L--------l

哦哦看到了，那CODEBLOCKS里面 如果编译后 结果为警告，要不要紧，影不影响程序的执行

这里还有一段，麻烦您看看
