如何將變量傳遞給一個類

Question

我一直在研究這段代碼很久，現在我已經發布了它，但之後解決了這個問題後又出現了另一個問題，於是我創建了一個新的帖子，其中包含這個問題的名稱。好的問題是，我顯然沒有以正確的方式將變量傳遞給Administrator類。我已經嘗試了兩種方式這是我所有的書節目，既給了我，說錯誤C2512錯誤：「SalariedEmployee」：沒有可用的適當的默認構造函數」我已經嘗試了

Answer 1

Administrator(string t, string r, string s, double sa);將嘗試調用基類的默認構造函數，如果你沒有指定其他。（默認構造函數是一個可以不帶任何參數調用）

基類沒有默認構造函數，ERGO錯誤。

調用基類的另一個構造函數：

Administrator::Administrator(string t, string r, string s, double sa) : 
SalariedEmployee(<args>), //base constructor call 
title(t), responsi(r), super(s), salary(sa) //members 
{ 
}
