linknode *head,*tail;int length;}linklist;首先typedef的意思是定义一个新类型，上面的结构体被定义成linknode，下面的结构体被定义成linklist，linknode是链表结点结构，而linklist是链表管理结构，linklist里有两个成员变量head和tail，类型都是linknode指针，表示这两个指针一个指向链表头，一个指向...

在main函数中,首先创建一个结点,令尾指针指向该结点:tail=(link)malloc(sizeof(node));,由于后面第二句ptr=tail令工作指针指向尾结点,可知第一个空填NULL,即将尾结点的指针域置为NULL,tail一>next=NULL;。for循环的作用是依次创建5个结点,并为这5个结点的数据域赋值。由ptr—>data=num;可知其前一句是用num...
