[問題] 動態class釋放
開發平台(Platform): (Ex: VC++, GCC, Linux, ...)
BCB
程式碼(Code)：(請善用置底文網頁, 記得排版)
class OneInfo
{
public:
int Value;
};
class TwoInfo
{
public:
OneInfo One;
};
class ThreeInfo
{
public:
TwoInfo *Two;
};
========================
void __fastcall TForm1::Button1Click(TObject *Sender)
{
int ThreeNum=3, TwoNum=2;
ThreeInfo *Three;
Three = new ThreeInfo[ThreeNum];
for (int i=0; i<ThreeNum; i++)
{
Three[i].Two = new TwoInfo[TwoNum];
for (int j=0; j<TwoNum; j++)
{
Three[i].Two[j].One.Value=i+j;
}
}
//^^^^^^^^^^^^^動態宣告了一個三層的class
//vvvvvvvvvvvvv想要釋放所宣告的動態class
for (int i=0; i<ThreeNum; i++)
{
for (int j=0; j<TwoNum; j++)
{
delete[] Three[i].Two[j]; //<--這樣寫不會過
//E2157 Deleting an object requires exactly one
//conversion to pointer operator
}
}
}
======================
請問一下要如何寫呢?
新手笨問題..請見諒
