顺序表是在计算机内存中以数组的形式保存的线性表,是指用一组地址连续的存储单元依次存储数据元素的线性结构。线性表采用顺序存储的方式存储就称之为顺序表。顺序表是将表中的结点依次存放在计算机内存中一组地址连续的存储单元中。
将表中元素一个接一个的存入一组连续的存储单元中,这种存储结构是顺序结构。

顺序存储结构
在计算机中用一组地址连续的存储单元依次存储线性表的各个数据元素,称作线性表的顺序存储结构.
顺序存储结构是存储结构类型中的一种,该结构是把逻辑上相邻的节点存储在物理位置上相邻的存储单元中,结点之间的逻辑关系由存储单元的邻接关系来体现。由此得到的存储结构为顺序存储结构,通常顺序存储结构是借助于计算机程序设计语言(例如c/c++)的数组来描述的。
顺序存储结构的主要优点是节省存储空间,因为分配给数据的存储单元全用存放结点的数据(不考虑c/c++语言中数组需指定大小的情况),结点之间的逻辑关系没有占用额外的存储空间。采用这种方法时,可实现对结点的随机存取,即每一个结点对应一个序号,由该序号可以直接计算出来结点的存储地址。但顺序存储方法的主要缺点是不便于修改,对结点的插入、删除运算时,可能要移动一系列的结点。
优点:
随机存取表中元素。缺点:插入和删除操作需要移动元素。
本代码默认list可以容纳的item数目为100个,用户可以自行设置item数目。当list饱和时,会自动以2倍的长度进行递增。

AL_ListSeq.h
/** @(#)$Id: AL_ListSeq.h 44 2013-09-13 08:50:04Z xiaoting $ @brief Sequence table is in the computer memory as an array stored linear form, refers to a group of contiguous memory cells storing data elements sequentially linear structure. Linear form using sequential storage mode it is called the order form. Sequence table is the table node sequentially stored in the computer memory a set of contiguous memory cell. ////////////////////////////////Sequential storage structure////////////////////////////////////////// Using a set of addresses in the computer storage unit sequentially stores continuous linear form of individual data elements, called the linear order of the table storage structure. Sequential storage structure is a type of a storage structure, the structure is the logically adjacent nodes stored in the physical location of the adjacent memory cells, the logical relationship between nodes from the storage unit to reflect the adjacency. Storage structure thus obtained is stored in order structure, usually by means of sequential storage structure computer programming language (e.g., c / c) of the array to describe. The main advantage of the storage structure in order to save storage space, because the allocation to the data storage unit storing all nodes with data (without regard to c / c language in the array size required for the case), the logical relationship between the nodes does not take additional storage space. In this method, the node can be realized on a random access, that is, each node corresponds to a number, the number can be calculated directly from the node out of the memory address. However, the main disadvantage of sequential storage method is easy to modify the node insert, delete operations, may have to move a series of nodes. Benefits: Random Access table elements. Disadvantages: insert and delete operations need to move elements. @Author $Author: xiaoting $ @Date $Date: 2013-09-13 16:50:04 +0800 (周五, 13 九月 2013) $ @Revision $Revision: 44 $ @URL $URL: https://svn.code.sf.net/p/xiaoting/game/trunk/MyProject/AL_DataStructure/groupinc/AL_ListSeq.h $ @Header $Header: https://svn.code.sf.net/p/xiaoting/game/trunk/MyProject/AL_DataStructure/groupinc/AL_ListSeq.h 44 2013-09-13 08:50:04Z xiaoting $ */ #ifndef CXX_AL_LISTSEQ_H #define CXX_AL_LISTSEQ_H /////////////////////////////////////////////////////////////////////////// // AL_ListSeq /////////////////////////////////////////////////////////////////////////// template<typename T> class AL_ListSeq { public: static const DWORD LISTSEQ_DEFAULTSIZE = 100; static const DWORD LISTSEQ_MAXSIZE = 0xffffffff; static const DWORD LISTSEQ_POSITION_INVALID = 0xffffffff; /** * Construction * * @param DWORD dwSize (default value: LISTSEQ_DEFAULTSIZE) * @return * @note * @attention */ AL_ListSeq(DWORD dwSize = LISTSEQ_DEFAULTSIZE); /** * Destruction * * @param * @return * @note * @attention */ ~AL_ListSeq(); /** * Length * * @param VOID * @return DWORD * @note get the length of the list * @attention */ DWORD Length() const; /** * Find * * @param const T& tTemplate <IN> * @return DWORD * @note find the position of tTemplate * @attention if not find, will be return 0xffffffff */ DWORD Find(const T& tTemplate) const; /** * IsElement * * @param const T& tTemplate <IN> * @return BOOL * @note the tTemplate is in the list?
