4. When the clerk is about to process a new ice scream order, some radio buttons
   should be selected already, those that would be the default.
   To select the default radio buttons, display the OnInitDialog() event of the dialog
   box and change it as follows:

// IceScreamOrderDlg.cpp : implementation file

//

#include "stdafx.h"

#include "Clarksville Ice Scream1.h"

#include "IceScreamOrderDlg.h"

// CIceScreamOrderDlg dialog

IMPLEMENT_DYNAMIC(CIceScreamOrderDlg, CDialog)

CIceScreamOrderDlg::CIceScreamOrderDlg(CWnd* pParent /*=NULL*/)

: CDialog(CIceScreamOrderDlg::IDD, pParent)

, m_Price(_T("$2.60"))

{

}

CIceScreamOrderDlg::~CIceScreamOrderDlg()

{

}

void CIceScreamOrderDlg::DoDataExchange(CDataExchange* pDX)

{

CDialog::DoDataExchange(pDX);

DDX_Control(pDX, IDC_FLAVORS, m_Flavors);

DDX_Control(pDX, IDC_RDO_CUP, m_Container);

DDX_Control(pDX, IDC_IGR_NONE, m_Ingredient);

DDX_Control(pDX, IDC_SCOOPS_ONE, m_Scoops);

DDX_Text(pDX, IDC_PRICE, m_Price);

}
