[問題] 請問struct裡的element可再動態宣告嗎?
請問struct裡的element可以再動態宣告嗎?
head檔===
class TForm1 : public TForm
{
__published: // IDE-managed Components
TButton *Button1;
void __fastcall Button1Click(TObject *Sender);
private: // User declarations
public: // User declarations
__fastcall TForm1(TComponent* Owner);
struct rainfall{
float *value;
};
rainfall *station;
};
cpp檔===
void __fastcall TForm1::Button1Click(TObject *Sender)
{
int num=100;
station = new rainfall[num];
//動態宣告station沒問題
for(int i=0; i<num; i++){
float *station[i].value = new float[num];
//上面這不行
//[C++ Error] Unit1.cpp(27): E2313 Constant expression required
//[C++ Error] Unit1.cpp(27): E2141 Declaration syntax error
}
}
請問有類似這樣的寫法嗎?
新手笨問題請多包涵
謝謝
