list makeempty()
; position find
( list l, elementtype x )
;bool insert
( list l, elementtype x, position p )
;bool delete
( list l, position p )
;
其中list結構定義如下:
typedef
struct lnode *ptrtolnode;
struct lnode
;typedef ptrtolnode position;
typedef ptrtolnode list;
各個操作函式的定義為:
list makeempty():建立並返回乙個空的線性表;
position find( list l, elementtype x ):返回線性表中x的位置。若找不到則返回error;
bool insert( list l, elementtype x, position p ):將x插入在位置p指向的結點之前,返回true。如果引數p指向非法位置,則列印「wrong position for insertion」,返回false;
bool delete( list l, position p ):將位置p的元素刪除並返回true。若引數p指向非法位置,則列印「wrong position for deletion」並返回false。
