void __fastcall TForm1::Button1Click(TObject *Sender)
{
    ostringstream  outstream;
  stack > s;
  s.push('+');
  s.push('-');
  s.push('#');
  for(s.top();s.top()!=s.empty() ;s.pop())
  {
  outstream<Lines->Add(outstream.str().c_str());      }
} 

引言:

void __fastcall TForm1::Button1Click(TObject *Sender)
{
    ostringstream  outstream;
  stack > s;
  s.push('+');
  s.push('-');
  s.push('#');
  for(s.top();s.top()!=s.empty() ;s.pop())
  {
  outstream<Lines->Add(outstream.str().c_str());      }
} 

怪怪...我ㄉ目的是要memo1顯示 memo1 # - + 這ㄍ 但卻顯示上圖 請大大指導....Orz

void __fastcall TForm1::Button1Click(TObject *Sender)

  ostringstream  outstream;
  stack > s;
  s.push('+');
  s.push('-');
  s.push('#');      while(!s.empty())
  {
    outstream.str("");
    outstream << s.top();
    s.pop();
    Memo1->Lines->Add(outstream.str().c_str());
  }
