C++図書館管理プログラム(継承、マルチステート)

分析:1.元の図書館管理プログラムでは、私はベースクラスのUserが1つしかなく、それから人員の継承を実現し、書籍の継承を完了していません.だから新しいプログラムの中で、私は新しいBookクラスをベースクラスとして追加して、それから新しいクラスとFileManagementクラスを派生して、各種の情報の記憶に用いて、私はこのプログラムの中で、依然としてファイルの記憶を使って、書籍と読者に対して添削して調べる過程の中で、プログラムはそれに応じてtextドキュメントの情報を修正します.　　　 2. そして、異なるユーザーを区別するために、異なる操作を行うために、ユーザーは初期にログインし、システムはユーザーのアカウントによって異なる役割のユーザーを区別する(管理者のアカウントは文字Aから始まり、普通のユーザーのアカウントは文字Uから始まる)、それぞれ異なるユーザーインタフェースに入り、この機能は虚関数を使って多態を実現することができる.3.管理者は本の情報を見ることができ、本の情報を追加、削除、修正することができる.4.普通のユーザーはすべての本の情報、具体的な1冊の本の情報と本を借りて、本を返すことができます;　　　 5. クラスの説明は以下の通りです:(1)Peopleはユーザーのアカウントパスワード属性(private)を保存し、対応するset、get方法を提供します.(2)UserはPeopleから継承し、display()を書き換え、以下の機能を追加する:viewBookInfo()図書詳細情報を表示BorrowBook()貸し出し図書ReturnBook()図書を返却する機能(3)AdministratorはPeopleから継承し、display()を書き換える以下の機能を追加します:addBook()図書deleteBook()図書reSetBook()図書を削除します(4)Bookのすべての本クラスのベースクラスを修正して、本の各種の属性を持って、そして相応のset、get方法と虚関数toString()を提供します;　　　 (5)E_Book、Magazine、Movie、MusicはBookから継承され、toString()を書き換える.(6)DVDはムービーから引き継ぐ;(7)3種類のFileManagement:①map getPeopleInfo()はユーザファイルpeopleを担当する.txt情報読み取り②vector getBooks()は、本情報ファイルbookを担当する.txtは、③void saveBooks(vectorvec)の読み取りと、ブック情報の修正④Book*getObject(string ID)の保存を行い、ブックのID情報に基づいて、対応するタイプのオブジェクトポインタを返す.
以上は私の分析で、私も1つの完全な実験報告を書いたことがあって、中には類の詳しい設計に対して含んで、興味があるのはダウンロードして見て、みんなに役に立つことを望んで、最終的にやはりみんなに頼って自分で悟って、その中の原理を理解します.ダウンロードしたい場合はDownloadをクリックしてください
