編程題2_數(shù)據(jù)及教師學(xué)生類

1、名稱編程題2_數(shù)據(jù)及教師學(xué)生類備注描述題目描述：有五個類，各類的主要數(shù)據(jù)成員見下方說明，請自己定義合理的成員函數(shù)，編程實現(xiàn)體現(xiàn)該繼承 關(guān)系的程序，并定義教師對象、學(xué)生對象、研究生對象、在職研究生對象，輸出他們的信息。關(guān)于數(shù)據(jù)成員：數(shù)據(jù)類Data :成員name 保存姓名；/該類是Teacher類和Student類的基類教師類Teacher :增加成員sal保存工資；學(xué)生類Student :增加成員id保存學(xué)號； 該類是PostGrad 類的基類研究生類PostGrad :增加成員dn保存系別；教師中的在職研究生類 Tpost ：不另外定義數(shù)據(jù)成員。該類有兩個直接基類：Teacher類和研 究生

2、類PostGrad關(guān)于成員函數(shù)：每個類中均定義輸出所有數(shù)據(jù)成員的函數(shù)void print ()。具體代碼可參考主函數(shù)及對應(yīng)的輸出結(jié)果樣例來完成。主函數(shù)代碼如下：int main ()Teacher tobj("Zhuhong”, 2000);Student sobj("Wanghui", "B05030417");PostGrad pobj("Lixuefeng", "Yj040217", "Computer Department");Tposttpobj("Liuling&
