軟件基礎(chǔ)課程設(shè)計(jì)報(bào)告 一、需求分析系統(tǒng)目標(biāo)：設(shè)計(jì)的計(jì)算器至少能夠進(jìn)行簡(jiǎn)單的四則運(yùn)算和求倒數(shù)求反以及開方運(yùn)算。主體功能：程序能實(shí)現(xiàn)：加，減，乘，除，開方，倒數(shù)等運(yùn)算功能；還要實(shí)現(xiàn)數(shù)據(jù)的輸入，輸出，計(jì)算，顯示及程序退出等功能。另外還可以實(shí)現(xiàn)多種科學(xué)計(jì)算的功能，如：三角函數(shù)的計(jì)算，弧度與角度間的轉(zhuǎn)換，對(duì)數(shù)指數(shù)的計(jì)算等。開發(fā)環(huán)境：操作系統(tǒng)：Windows XP編程環(huán)境：MicrosoftVisualC+6.0 二、功能說明(1)包含的功能有：加、減、乘、除運(yùn)算，開方、求倒數(shù)、三角函數(shù)、弧度與角度間的轉(zhuǎn)換、對(duì)數(shù)指數(shù)的計(jì)算等功能。(2)計(jì)算器上數(shù)字09為一個(gè)控件數(shù)組，加、減、乘、除為一個(gè)控件數(shù)組，其余為單一的控件。(3)給對(duì)話框添加菜單。(4)計(jì)算功能基本上是用系統(tǒng)內(nèi)部函數(shù)。(5)程序可以能自動(dòng)判斷輸入數(shù)據(jù)的正確性，保證不出現(xiàn)多于一個(gè)小數(shù)點(diǎn)、以0開頭等不正?，F(xiàn)象。(6)“CE”按鈕可以清除所有已輸入的數(shù)據(jù)從頭計(jì)算，“Back”按鈕可以實(shí)現(xiàn)退位功能。（7）能夠顯示時(shí)間、日期。三、詳細(xì)設(shè)計(jì)（1）流程圖創(chuàng)建工程（創(chuàng)建一個(gè)對(duì)話框應(yīng)用程序）設(shè)計(jì)對(duì)話框界面設(shè)置各控件屬性為編輯框連接成員變量為類添加數(shù)據(jù)成員，初始化構(gòu)造函數(shù)。為所有按鈕添加事件對(duì)類添加成員函數(shù)（更新編輯框）并進(jìn)行實(shí)現(xiàn)實(shí)現(xiàn)對(duì)各按鈕事件的實(shí)現(xiàn)（2）編輯資源（3）效果圖四、程序附錄計(jì)算器Dlg.cpp :#include stdafx.h#include 計(jì)算器.h#include 計(jì)算器Dlg.h#include math.h#includeFirstDlg.h#include #define PI 3.14;#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()/ CMyDlg dialogCMyDlg:CMyDlg(CWnd* pParent /*=NULL*/): CDialog(CMyDlg:IDD, pParent)/AFX_DATA_INIT(CMyDlg)m_result = 0.0;/AFX_DATA_INIT/ Note that LoadIcon does not require a subsequent DestroyIcon in Win32m_hIcon = AfxGetApp()-LoadIcon(IDR_MAINFRAME);void CMyDlg:DoDataExchange(CDataExchange* pDX)CDialog:DoDataExchange(pDX);/AFX_DATA_MAP(CMyDlg)DDX_Control(pDX, IDC_EDIT1, m_EDIT);DDX_Text(pDX, IDC_EDIT1, m_result);/AFX_DATA_MAPBEGIN_MESSAGE_MAP(CMyDlg, CDialog)/AFX_MSG_MAP(CMyDlg)ON_WM_SYSCOMMAND()ON_WM_PAINT()ON_WM_QUERYDRAGICON()ON_BN_CLICKED(IDC_NUM0, OnNum0)ON_BN_CLICKED(IDC_NUM1, OnNum1)ON_BN_CLICKED(IDC_NUM2, OnNum2)ON_BN_CLICKED(IDC_NUM3, OnNum3)ON_BN_CLICKED(IDC_NUM4, OnNum4)ON_BN_CLICKED(IDC_NUM5, OnNum5)ON_BN_CLICKED(IDC_NUM6, OnNum6)ON_BN_CLICKED(IDC_NUM7, OnNum7)ON_BN_CLICKED(IDC_NUM8, OnNum8)ON_BN_CLICKED(IDC_NUM9, OnNum9)ON_BN_CLICKED(IDC_DOT, OnDot)ON_BN_CLICKED(IDC_CE, OnCe)ON_BN_CLICKED(IDC_jia, Onjia)ON_BN_CLICKED(IDC_jian, Onjian)ON_BN_CLICKED(IDC_cheng, Oncheng)ON_BN_CLICKED(IDC_chu, Onchu)ON_BN_CLICKED(IDC_dengyu, Ondengyu)ON_BN_CLICKED(IDC_daoshu, Ondaoshu)ON_BN_CLICKED(IDC_zhengfu, Onzhengfu)ON_BN_CLICKED(IDC_BACKSPACE, OnBackspace)ON_BN_CLICKED(IDC_Ln, OnLn)ON_BN_CLICKED(IDC_log, Onlog)ON_BN_CLICKED(IDC_RADIO2, OnRadio2)ON_BN_CLICKED(IDC_RADIO1, OnRadio1)ON_BN_CLICKED(IDC_sqrt, Onsqrt)ON_BN_CLICKED(IDC_sin, Onsin)ON_BN_CLICKED(IDC_cos, Oncos)ON_BN_CLICKED(IDC_tan, Ontan)ON_BN_CLICKED(IDC_pingfang, Onpingfang)ON_BN_CLICKED(IDC_lifang, Onlifang)ON_BN_CLICKED(IDC_mi, Onmi)ON_BN_CLICKED(IDC_Exp, OnExp)ON_BN_CLICKED(IDC_10demi, On10demi)ON_BN_CLICKED(IDC_jiecheng, Onjiecheng)ON_COMMAND(ID_TIME, OnTime)ON_COMMAND(ID_DATE, OnDate)ON_COMMAND(ID_EXIT, OnExit)ON_COMMAND(ID_HELP, OnHelp)/AFX_MSG_MAPEND_MESSAGE_MAP()/ CMyDlg message handlersBOOL CMyDlg: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.
