帶表頭結點單鏈表的構造、插入和刪除函式：

template


<


class


t>


headerlist


::headerlist()


template


<


class


t>


headerlist


::insert


(int i,t x)


node


* p = first;


for(


int j =


0; j <= i; j++


) p = p-


>link;


node


* q =


new node


; q-


>element = x;


q->link = p-


>link;


p->link = q;


n++;return


true


;}
template


<


class


t>


headerlist


::delete


(int i)


if(i<


0|| i>n -1)


node


* q = first,


*p;for


(int j =


0; j < i; j++


) q = q-


>link;


p - q-


>link;


q->link = p-


>link;


delete p;


n--;return


true


;}
雙向鍊錶：

template


class


doublelist


;template


class


dnode


;插入操作：(在p結點前插入)


dnode


*q=new dnode;q-


>element=x;


q->llink=p-


>llink;


q->rlink=p;


p->llink-


>rlink=q;


p->llink=q;


刪除操作：


p->llink-


>rlink=p-


>rlink;


p->rlink-


>llink=p-


>llink;


delete p;
