引言: QUEST1.BCB裡的qsort可以排序二個陣列資料嗎?就是排序A陣列，而B陣列就排得與A陣列相同~~ QUEST2.BCB裡的qsort可以排序struct嗎? 感謝大家的幫忙哦~ < face="Verdana, Arial, Helvetica">

黑輪你好:
第一個問題可能沒辦法!!
第二個問題請參考下列的程式碼    struct AreaNo
{
  int Sequence;
  int No;
};    int StructCompare(const void *cmp1,const void *cmp2);    void __fastcall TForm1::Button1Click(TObject *Sender)
{
  const int MaxAreas = 10;
  struct AreaNo sAreaNo[MaxAreas];      for (int i = 0; i < MaxAreas; i  )
  {
    sAreaNo[i].Sequence = i   1;        //序號從1開始
    sAreaNo[i].No = MaxAreas - i;       //區域編號初始值(由 MaxAreas 遞減)
  }      qsort(sAreaNo,MaxAreas,sizeof(AreaNo),StructCompare);  //排序陣列結構      for (int i = 0; i < MaxAreas; i  )
    ListBox1->Items->Add(AnsiString(sAreaNo[i].Sequence)   " -> "  
                         AnsiString(sAreaNo[i].No));
}    int StructCompare(const void *cmp1,const void *cmp2)
{
 struct AreaNo *sAreaNo1,*sAreaNo2;     sAreaNo1 = (struct AreaNo *)cmp1;
 sAreaNo2 = (struct AreaNo *)cmp2;     return (sAreaNo1->No - sAreaNo2->No);
}
