71、概念</b></p><p>　　數據結構是計算機科學與技術專業(yè)的專業(yè)基礎課，是十分重要的核心課程。所有的計算機系統軟件和應用軟件都要用到各種類型的數據結構。因此，要想更好地運用計算機來解決實際問題，僅掌握幾種計算機程序設計語言是難以應付眾多復雜的課題的。要想有效地使用計算機、充分發(fā)揮計算機的性能，還必須學習和掌握好數據結構的有關知識。打好“數據結構”這門課程的扎實基礎，對于學習計算機專業(yè)的其他課程，

72、如操作系統、編譯原理、數據庫管理系統、軟件工程、人工智能等都是十分有益的。</p><p>　　二，為什么要學習數據結構</p><p>　　在計算機發(fā)展的初期，人們使用計算機的目的主要是處理數值計算問題。當我們使用計算機來解決一個具體問題時，一般需要經過下列幾個步驟：首先要從該具體問題抽象出一個適當的數學模型，然后設計或選擇一個解此數學模型的算法，最后編出程序進行調試、測試，直至得到最終

73、的解答。例如，求解梁架結構中應力的數學模型的線性方程組，該方程組可以使用迭代算法來求解。</p><p>　　由于當時所涉及的運算對象是簡單的整型、實型或布爾類型數據，所以程序設計者的主要精力是集中于程序設計的技巧上，而無須重視數據結構。隨著計算機應用領域的擴大和軟、硬件的發(fā)展，非數值計算問題越來越顯得重要。據統計，當今處理非數值計算性問題占用了90%以上的機器時間。這類問題涉及到的數據結構更為復雜，數據元素之間

74、的相互關系一般無法用數學方程式加以描述。因此，解決這類問題的關鍵不再是數學分析和計算方法，而是要設計出合適的數據結構，才能有效地解決問題。</p><p>　　描述這類非數值計算問題的數學模型不再是數學方程，而是諸如表、樹、圖之類的數據結構。因此，可以說數據結構課程主要是研究非數值計算的程序設計問題中所出現的計算機操作對象以及它們之間的關系和操作的學科。</p><p>　　學習數據結構的

75、目的是為了了解計算機處理對象的特性，將實際問題中所涉及的處理對象在計算機中表示出來并對它們進行處理。與此同時，通過算法訓練來提高學生的思維能力，通過程序設計的技能訓練來促進學生的綜合應用能力和專業(yè)素質的提高。</p><p><b>　　三，有關概念和術語</b></p><p>　　在系統地學習數據結構知識之前，先對一些基本概念和術語賦予確切的含義。</p&g

76、t;<p>　　數據（Data）是信息的載體，它能夠被計算機識別、存儲和加工處理。它是計算機程序加工的原料，應用程序處理各種各樣的數據。計算機科學中，所謂數據就是計算機加工處理的對象，它可以是數值數據，也可以是非數值數據。數值數據是一些整數、實數或復數，主要用于工程計算、科學計算和商務處理等；非數值數據包括字符、文字、圖形、圖像、語音等。</p><p>　　數據元素（Data Element）是數

77、據的基本單位。在不同的條件下，數據元素又可稱為元素、結點、頂點、記錄等。例如，學生信息檢索系統中學生信息表中的一個記錄、八皇后問題中狀態(tài)樹的一個狀態(tài)、教學計劃編排問題中的一個頂點等，都被稱為一個數據元素。</p><p>　　有時，一個數據元素可由若干個數據項（Data Item）組成，例如，學籍管理系統中學生信息表的每一個數據元素就是一個學生記錄。它包括學生的學號、姓名、性別、籍貫、出生年月、成績等數據項。這些

78、數據項可以分為兩種：一種叫做初等項，如學生的性別、籍貫等，這些數據項是在數據處理時不能再分割的最小單位；另一種叫做組合項，如學生的成績，它可以再劃分為數學、物理、化學等更小的項。通常，在解決實際應用問題時是把每個學生記錄當作一個基本單位進行訪問和處理的。</p><p>　　數據對象（Data Object）或數據元素類（Data Element Class）是具有相同性質的數據元素的集合。在某個具體問題中，數據

79、元素都具有相同的性質（元素值不一定相等），屬于同一數據對象（數據元素類），數據元素是數據元素類的一個實例。例如，在交通咨詢系統的交通網中，所有的頂點是一個數據元素類，頂點A和頂點B各自代表一個城市，是該數據元素類中的兩個實例，其數據元素的值分別為A和B。</p><p>　　數據結構（Data Structure）是指互相之間存在著一種或多種關系的數據元素的集合。在任何問題中，數據元素之間都不會是孤立的，在它們之

80、間都存在著這樣或那樣的關系，這種數據元素之間的關系稱為結構。根據數據元素間關系的不同特性，通常有下列四類基本的結構：</p><p>　?、偶辖Y構。在集合結構中，數據元素間的關系是“屬于同一個集合”。集合是元素關系極為松散的一種結構。</p><p>　?、凭€性結構。該結構的數據元素之間存在著一對一的關系。</p><p>　?、菢湫徒Y構。該結構的數據元素之間存在

81、著一對多的關系。</p><p>　?、葓D形結構。該結構的數據元素之間存在著多對多的關系，圖形結構也稱作網狀結構。</p><p>　　C++Builder程序設計經驗</p><p><b>　　數據庫程序設計</b></p><p>　　Borland C++Builder與Delphi一樣使用BDE（Borland

82、 </p><p>　　Database Engine）數據庫接口，特別是它使用BDE Administrator統一管理數據庫別名，使得數據庫操作與數據庫文件位置無關，從而使數據庫開發(fā)更容易操作。但在發(fā)布應用數據庫程序時我們不得不同時“發(fā)布”BDE，對于一些簡單的數據庫程序來說，可能BDE比我們的自己設計的程序還大，而且如使用InstallShield配置BDE，添加數據庫別名，很可能會配置失敗。所以我們可以采

83、用如下方法：在程序設計階段仍采用BDE管理數據庫別名進行調試，但在程序初始化時（如在主窗體的OnCreate事件處理函數中）修改Table部件的DatabaseName屬性，如使用類似如下語句： </p><p>　　Table1->DatabaseName = ExtractFilePath(Application->ExeName);或 Table1->DatabaseName </p

84、><p>　　= ExtractFilePath(Application->ExeName+”DB”); </p><p>　　這樣，對調試階段沒有什么影響，發(fā)布應用程序時只要將Table1使用的數據庫文件放在當前目錄或其“DB”子目錄下，數據庫程序即可正常運行。甚至您還可以將數據庫文件所在目錄以字符串形式寫入注冊表（可在安裝程序中設置），然后在程序初始化時從注冊表獲取目錄名，賦值給Da

85、tabaseName屬性即可。無論怎樣，您不必強迫用戶安裝相對龐大的BDE了。</p><p><b>　　二、 注冊表存取 </b></p><p>　　在我們在設計Windows 9x/NT程序時經常需進行注冊表信息的存取，如讀取程序配置信息、保存配置信息等。寫一個注冊表存取子程序就很有必要。當需存取注冊表時，直接調用此子程序即可，而不必每次都重復一些操作。下面的

99、換，但有些應用程序不使用任務欄圖標，如典型的Office工具條，也有些程序可由用戶定制顯示方式顯示或隱藏任務欄圖標，如Winamp。我們的程序中也可以做到，只要調用Windows </p><p>　　API函數SetWindowLong即可，如下： </p><p>　　// 隱藏任務欄圖標：</p><p>　　SetWindowLong(Application

100、->Handle, </p><p>　　GWL_EXSTYLE, WS_EX_TOOLWINDOW);</p><p>　　// 顯示任務欄圖標：</p><p>　　SetWindowLong(Application->Handle,</p><p>　　GWL_EXSTYLE, WS_EX_APPWINDOW);</p

101、><p>　　四、 建立簡單的“關于”窗口 </p><p>　　一個完整的Windows應用程序一般都包含一個“關于”窗口，用以顯示版本信息等。通常我們是定制一個對話框作為“關于”窗口，當然這樣的“關于”窗口可以自由定制，顯示更多信息，甚至可包括超鏈接。但如只需顯示簡單版本信息等，</p><p>　　Windows Shell Library 函數ShellAbou

102、t已足夠了，下面這行代碼就可以顯示“關于”對話框，而且是Windows標準的“關于”對話框，同時可顯示程序圖標和系統資源使用情況等。 </p><p>　　ShellAbout(Handle, ("關于"+Application->Title+"#").c_str(),</p><p>　　("\n"+Application

103、->Title+" V1.0\n\n"+"夏登城 版權所有！").c_str(),</p><p>　　Application->Icon->Handle);</p><p>　　五、 選擇目錄的兩種方法 </p><p>　　在我們的應用程序中經常需讓用戶選擇目錄，如殺毒軟件中用戶選擇處理目錄等。這就涉及目

104、錄的選擇，我們可使用如下方法之一讓用戶選擇目錄： </p><p>　　1、 使用SHBrowseForFolder和SHGetPathFromIDList函數；其函數原形申明如下： </p><p>　　WINSHELLAPI LPITEMIDLIST WINAPI SHBrowseForFolder(LPBROWSEINFO lpbi); </p><p>　　

105、WINSHELLAPI BOOL WINAPI SHGetPathFromIDList(LPCITEMIDLIST pidl, LPSTR pszPath); LPBROWSEINFO和LPITEMIDLIST的結構請參考Win32文檔。這種方法選取目錄可獲得Windows桌面下所有可用的目錄，包括網絡鄰居中其它計算機的共享目錄等，但不可新建目錄。下面的例程可讓用戶選擇目錄，該例程返回指向所選擇目錄的全路徑字符串。 </p>

106、<p>　　#include < shlobj.h ></p><p>　　char *GetDir(char *DisplayName, HWND Owner) {</p><p>　　char dir[MAX_PATH] = "";</p><p>　　BROWSEINFO *bi = new BROWSEINFO;

110、<p><b>　　}</b></p><p>　　我們可作如下調用得到選擇的目錄名： </p><p>　　AnsiString Dir = (AnsiString)GetDir("請選擇目錄：", Handle);</p><p>　　2、 使用SelectDirectory函數。C++Builder提供的函

111、數SelectDirectory可實現目錄名的選擇，它顯示的是類似“打開”/“保存”的對話框，但其優(yōu)點是可使用/不使用鍵盤輸入目錄名，并允許創(chuàng)建新目錄。其原形定義如下： </p><p>　　extern PACKAGE bool __fastcall SelectDirectory(</p><p>　　AnsiString &Directory, TSelectDirOpts
