2、、性別和年齡。從CPerson類派生出CStudent類，增加屬性：學(xué)號(hào)、入學(xué)時(shí)間和入學(xué)成績(jī)；從CPerson類派生出CTeacher類，添加屬性：職務(wù)、部門和工作時(shí)間；由CStudent類派生出CGraduate類，添加屬性：研究方向和導(dǎo)師；由CGraduate和CTeacher共同派生出在職研究生類CGradonWork對(duì)上述類分別定義其中的構(gòu)造函數(shù)和輸出函數(shù)，并在主函數(shù)中定義對(duì)象進(jìn)行測(cè)試，測(cè)試的代碼大致如下：CGradonWork gradonWork(tzcer,男,33,15,2003,335,computer,tangmin,jsj,sxxy,2002-8);gradonWork.

3、Print();其中CGradonWork 的構(gòu)造函數(shù)參數(shù)分別對(duì)應(yīng)的屬性是一個(gè)在職的研究生對(duì)象，其姓名為tzcer，性別為男，33歲，學(xué)號(hào)15，2003年讀在職，入學(xué)成績(jī)335，就讀計(jì)算機(jī)方向，其導(dǎo)師tangmin，同時(shí)tzcer也是sxxy部門，jsj專業(yè)的老師，2002-8月入職。 要求記錄輸出信息并說(shuō)明實(shí)驗(yàn)步驟和解決方法！問(wèn)題：何為繼承二義性，在本實(shí)驗(yàn)中哪個(gè)地方存在二義性，你是如何解決的？定義形狀類，其中基類為點(diǎn)類，圓類繼承點(diǎn)類，圓柱體類繼承圓類，計(jì)算面積、體積。建立一個(gè)建筑物類的層次體系。其中，基類building包括保護(hù)數(shù)據(jù)成員name（建筑物名稱）、floors（層數(shù)）和areas

4、（總面積），由building類派生住宅類house和辦公樓類office；住宅類house包括私有數(shù)據(jù)成員rooms（房間數(shù)）和balcony（陽(yáng)臺(tái)數(shù)）；辦公樓類office包括私有數(shù)據(jù)成員offices（辦公室數(shù)）和meetingrooms（會(huì)議室數(shù)）。住宅類house和辦公樓類office都含有構(gòu)造函數(shù)和print函數(shù)，以分別用于對(duì)數(shù)據(jù)成員的初始化和輸出。在主函數(shù)中，實(shí)例化house類和office類對(duì)象并且將其數(shù)據(jù)輸出。某校每位學(xué)生都要學(xué)習(xí)英語(yǔ)、語(yǔ)文、數(shù)學(xué)三門公共課程以及不同的專業(yè)課程。會(huì)計(jì)學(xué)專業(yè)要學(xué)習(xí)會(huì)計(jì)學(xué)和經(jīng)濟(jì)學(xué)兩門課程，化學(xué)專業(yè)要學(xué)習(xí)有機(jī)化學(xué)和化學(xué)分析兩門課程。編程序管理學(xué)生成績(jī)
