Thread: array dimension

how can i make 400x400 dimension array. below is my code and the result is in one dimension(16000x1). i'm using C++ Builder.

Code:

void __fastcall TForm1::Button1Click(TObject *Sender)
{
   int DataWidth = Image1->Picture->Width;
   int DataHeight = Image1->Picture->Height;

   for (int y=0;y<DataHeight;y++)
      for (int x=0;x<DataWidth;x++)
         Data[y][x] = (Byte)Image1->Canvas->Pixels[x][y];


    TStringList*show = new TStringList;
     for (int j=0;j<400;j++)
        for (int i=0;i<400;i++)
              {
               show->Add(AnsiString(Data[i][j]));
               }
               show->SaveToFile("Luthor.dat");
             delete show;
}

You need to declare Data somewhere, proably using the new operator, and then associate DataWidth and DataHeight with x and y. If you want to make Data local the function posted you can do it there, otherwise, you probably have a mainForm with WINMAIN and the main() function listed somewhere. You can put it in there and then pass Data to the functions that need to use it.
