uj5u.com熱心網友回復：
這種問題編譯器會給出比較明確的提示，不需要來問吧。一篇過下來有兩個明顯的錯誤，錯誤原因一樣：public:
Retangle(int A,int B,int L,int W):Point(int A,int B)
向基類傳遞引數需要直接帶變數，而不是再次宣告原型，應該是：Retangle(int A,int B,int L,int W) : Point(A,B)
同理下面的也是錯誤的：
public:
Cube(int A,int B,int L,int W,int H):Retangle(int A,int B,int L,int W)
應該改成
Cube(int A,int B,int L,int W,int H):Retangle(A,B,L,W)
