Description
分別宣告Teacher(教師)類和Cadre(幹部)類,採用多重繼承方式由這兩個類派生出新類Teacher_Cadre(教師兼幹部)類。要求:
(1) 在兩個基類中都包含姓名、年齡、性別、地址、電話等資料成員。
(2) 在Teacher類中還包含資料成員title(職稱),在Cadre類中還包含資料成員post(職務)。在Teacher_Cadre類中還包含資料成員wages(工資)。
(3) 對兩個基類中的姓名、年齡、性別、地址、電話等資料成員用相同的名字,在引用這些資料成員時,指定作用域。
(4) 在類體中宣告成員函式,在類外定義成員函式。
(5) 在派生類Teacher_Cadre的成員函式show中呼叫Teacher類中的display函式,輸出姓名、年齡、性別、職稱、地址、電話,然後再用cout語句輸出職務與工資。
