院 系：计 算 机 学 院实验课程：计算机基础实验实验项目：程序设计入门基础指导老师：杨志强 开课时间：2010 2011年度第 2学期专 业：计算机类班 级： 10本4学 生：杨晓添学 号：20102100114华南师范大学教务处1. 题目：简单计算器2. 实验目的：模仿日常生活中所用的计算器，自行设计一个简单的计算器程序，实现简单的计算功能。3. 实验主要硬件软件环境：Window 7Visual C+ 6.04. 实验内容：(1) 体系设计：程序是一个简单的计算器，能正确输入数据，能实现加、减、乘、除等算术运算，能进行简单三角运算，运算结果能正确显示，可以清楚数据等。(2) 设计思路：1) 先在Visual C+ 6.0中建立一个MFC工程文件，名为calculator.2) 在对话框中添加适当的编辑框、按钮、静态文件、复选框和单选框3) 设计按钮，并修改其相应的ID与Caption.4) 选择和设置各控件的单击鼠标事件。5) 为编辑框添加double类型的关联变量m_edit1.6) 在calculatorDlg.h中添加math.h头文件，然后添加public成员。7) 打开calculatorDlg.cpp文件，在构造函数中，进行成员初始化和完善各控件的响应函数代码。(3) 程序清单：程序代码如下：/ calculator_1Dlg.cpp : implementation file/#include stdafx.h#include calculator_1.h#include calculator_1Dlg.h#ifdef _DEBUG#define new DEBUG_NEW#undef THIS_FILEstatic char THIS_FILE = _FILE_;#endif/ CAboutDlg dialog used for App Aboutclass CAboutDlg : public CDialogpublic:CAboutDlg();/ Dialog Data/AFX_DATA(CAboutDlg)enum IDD = IDD_ABOUTBOX ;/AFX_DATA/ ClassWizard generated virtual function overrides/AFX_VIRTUAL(CAboutDlg)protected:virtual void DoDataExchange(CDataExchange* pDX); / DDX/DDV support/AFX_VIRTUAL/ Implementationprotected:/AFX_MSG(CAboutDlg)/AFX_MSGDECLARE_MESSAGE_MAP();CAboutDlg:CAboutDlg() : CDialog(CAboutDlg:IDD)/AFX_DATA_INIT(CAboutDlg)/AFX_DATA_INITvoid CAboutDlg:DoDataExchange(CDataExchange* pDX)CDialog:DoDataExchange(pDX);/AFX_DATA_MAP(CAboutDlg)/AFX_DATA_MAPBEGIN_MESSAGE_MAP(CAboutDlg, CDialog)/AFX_MSG_MAP(CAboutDlg)/ No message handlers/AFX_MSG_MAPEND_MESSAGE_MAP()/ CCalculator_1Dlg dialogCCalculator_1Dlg:CCalculator_1Dlg(CWnd* pParent /*=NULL*/): CDialog(CCalculator_1Dlg:IDD, pParent)/AFX_DATA_INIT(CCalculator_1Dlg)m_edit1 = 0.0;/AFX_DATA_INIT/ Note that LoadIcon does not require a subsequent DestroyIcon in Win32m_hIcon = AfxGetApp()-LoadIcon(IDR_MAINFRAME);tempvalue=0;result=0;sort=0;append=0;void CCalculator_1Dlg:DoDataExchange(CDataExchange* pDX)CDialog:DoDataExchange(pDX);/AFX_DATA_MAP(CCalculator_1Dlg)DDX_Text(pDX, IDC_EDIT1, m_edit1);/AFX_DATA_MAPBEGIN_MESSAGE_MAP(CCalculator_1Dlg, CDialog)/AFX_MSG_MAP(CCalculator_1Dlg)ON_WM_SYSCOMMAND()ON_WM_PAINT()ON_WM_QUERYDRAGICON()ON_BN_CLICKED(IDC_BUTTON1, OnButton1)ON_BN_CLICKED(IDC_BUTTON2, OnButton2)ON_BN_CLICKED(IDC_BUTTON3, OnButton3)ON_BN_CLICKED(IDC_BUTTON4_plus, OnBUTTON4plus)ON_BN_CLICKED(IDC_BUTTON5_4, OnButton54)ON_BN_CLICKED(IDC_BUTTON6_5, OnButton65)ON_BN_CLICKED(IDC_BUTTON7_6, OnButton76)ON_BN_CLICKED(IDC_BUTTON8_minus, OnBUTTON8minus)ON_BN_CLICKED(IDC_BUTTON12_multi, OnBUTTON12multi)ON_BN_CLICKED(IDC_BUTTON16_div, OnBUTTON16div)ON_BN_CLICKED(IDC_BUTTON9_7, OnButton97)ON_BN_CLICKED(IDC_BUTTON10_8, OnButton108)ON_BN_CLICKED(IDC_BUTTON11_9, OnButton119)ON_BN_CLICKED(IDC_BUTTON13_zero, OnBUTTON13zero)ON_BN_CLICKED(IDC_BUTTON14_equal, OnBUTTON14equal)ON_BN_CLICKED(IDC_RADIO1_sin, OnRADIO1sin)ON_BN_CLICKED(IDC_RADIO2_cos, OnRADIO2cos)ON_BN_CLICKED(IDC_RADIO3_tan, OnRADIO3tan)ON_BN_CLICKED(IDC_RADIO5_log10, OnRADIO5log10)ON_BN_CLICKED(IDC_BUTTON15_clean, OnBUTTON15clean)/AFX_MSG_MAPEND_MESSAGE_MAP()/ CCalculator_1Dlg message handlersBOOL CCalculator_1Dlg:OnInitDialog()CDialog:OnInitDialog();/ Add About. menu item to system menu./ IDM_ABOUTBOX must be in the system command range.ASSERT(IDM_ABOUTBOX & 0xFFF0) = IDM_ABOUTBOX);ASSERT(IDM_ABOUTBOX AppendMenu(MF_SEPARATOR);pSysMenu-AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);/ Set the icon for this dialog.
