请教遍历的问题

问题：构造选择集，获取选择集里的特征点并充放在数组中，然后在比较特征点在数组中的位置。以下是代码，但结果总是不正确，虽然调试是通了。
请各位帮忙，谢谢！

void zhao_rank() {  // TODO: Implement the command  int i,cod_number;  int j;  long ilast;  ads_name ent;  float coordinate;
 acedSSLength(ssname,&ilast);
 AcDbEntity *pEntity;  AcDbObjectId objId;  //*********以下程序是将选择集中实体坐标储存在二维数组***********//   for(i=1;i<ilast+1;i++)  {   acedSSName(ssname,ilast-i,ent);   acdbGetObjectId(objId,ent);   acdbOpenObject(pEntity,objId,AcDb::kForRead);//打开点实体      if(pEntity->isKindOf(AcDbCircle::desc()))   {    // 显示圆的圆心    AcDbCircle *pCircle = AcDbCircle::cast(pEntity);    AcGePoint3d ptCenter;    ptCenter = pCircle->center();      coordinate=ptCenter;    coordinate=ptCenter;    coordinate=ptCenter;   }   if(pEntity->isKindOf(AcDbPoint::desc()))   {    // 显示点的坐标    AcDbPoint *pPoint = AcDbPoint::cast(pEntity);    AcGePoint3d ptPoint;    ptPoint = pPoint->position();      coordinate=ptPoint;    coordinate=ptPoint;    coordinate=ptPoint;   }   pEntity->close();  }

 //*********以下程序是为实体标号***********//  for(i=1;i<ilast+1;i++) {  cod_number=1;  acedSSName(ssname,ilast-i,ent);  acdbGetObjectId(objId,ent);  acdbOpenObject(pEntity,objId,AcDb::kForRead);//打开点实体  if(pEntity->isKindOf(AcDbCircle::desc()))  {   AcDbCircle *pCircle = AcDbCircle::cast(pEntity);   AcGePoint3d ptCenter;   ptCenter = pCircle->center();   for(j=1;j<ilast+1;j++)   if(ptCenter<coordinate||(ptCenter==coordinate&&ptCenter<coordinate))    cod_number=cod_number+1;   acutPrintf("\n %d",cod_number);  }  if(pEntity->isKindOf(AcDbPoint::desc()))  {   AcDbPoint *pPoint = AcDbPoint::cast(pEntity);   AcGePoint3d ptPoint;   ptPoint = pPoint->position();   for(j=1;j<ilast+1;j++)    if(ptPoint<coordinate||(ptPoint==coordinate&&ptPoint<coordinate))     cod_number=cod_number+1;    acutPrintf("\n %d",cod_number);  }  
}  acedSSFree(ssname); }
