C语言编程有了进一步的认识，对MicrosoftVisualC++6.0 这个程序的操作更加熟练了一些。回顾此次的课程设计，我学到了很多东西不仅巩固了书本的知识并且与实践相结合提高具体操作能力，在设计的过程中发现自己的不足，有些知识掌握的不够牢靠，通过这次的课程设计之后我把前面所学的知识又重新温故了一遍。同时，在老师和同学身上我学到了很多非常实用的知识，在此对给过我帮助的同学和老师表示由衷的感谢！参考文献[1]谭浩强・C程序设计（第三版）[M]・北京：清华大学出版社，2005.⑵谭浩强・C程序设计题解与上机指导（第三版）[M]・北京：清华大学出版社，2005.[3]甄炜.C++语言和面向对象程序设计教程[M]・北京：机械工业出版社，2005.附录1源程序清单//CalculatorDlg.cpp:implementationtile#include"stdaix.h"#include"Calculator.h"#include"CalculatorDlg.h"#include"math.h"#iftlef_DEBUG#detinenewDEBUG_NEW#undefTHIS_FILEstaticcharTHIS_FILE[]=__FILE__;#endiflllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllll//CAboutDlgdialogusedforAppAboutclassCAboutDlg:publicCDialog{public:CAboutDlg();//DialogData//{{AFX_DATA(CAboutDlg)enum{IDD=IDD_ABOUTBOX};//})AFX_DATA//ClassWizardgeneratedvirtualfunctionoverrides//{{AFX_VIRTUAL(CAboutDlg)//DDX/DDVsupportprotected://DDX/DDVsupportvirtualvoidDoDataExchange(CDataExchange*pDX);//}}AFX_VIRTUAL//Implementationprotected://{{AFX_MSG(CAboutDlg)//}}AFX_MSGDECLARE_MESSAGE_MAP()}；CAboutDlg::CAboutDlg():CDialog(CAboutDlg::IDD){//{{AFX_DATA_INIT(CAboutDlg)//}}AFX_DATA_INIT}voidCAboutDlg::DoDataExchange(CDataExchange*pDX){CDialog::DoDataExchange(pDX);//{{AFX_DATA_MAP(CAboutDlg)//}}AFX_DATA_MAP}BEGIN_MESSAGE_MAP(CAboutDlg,CDialog)//{{AFX_MSG_MAP(CAboutDlg)//Nomessagehandlers//}}AFX_MSG_MAPEND_MESSAGE_MAP()lllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllll//CCalculatorDlgdialogCCalculatorDlg::CCalculatorDlg(CWnd*pParent/*=NULL*/):CDialog(CCalculatorDlg::IDD,pParent){//{{AFX_DATA_INIT(CCalculatorDlg)m_result=_T(,H,);m_isDegree=-1;m_sentific=・1;//}}AFX_DATA_INrr//NotethatLoadicondoesnotrequireasubsequentDestroyIconinWin32m_hlcon=AlxGetApp()->LoadIcon(IDR_MAINFRAME);m_hAccel=LoadAccelerators(AixGetinstaneeHandle(),MAKEINTRESOURCE(IDD));DtoR=l;m_coff=0.1;m_bCoff=0;m_errorState=ErrNone;m_bOperandAvail=FALSE;m_operator=OpNone;}voidCCalculatorDlg::DoDataExchange(CDataExchange*pDX){CDialog::DoDataExchange(pDX);//{{AFX_DATA_MAP(CCalculatorDlg)DDX_Text(pDX,IDC_DISPLAY,m_result);DDX_Radio(pDX,IDC_DEGREE,m_isDegree);DDX_Radio(pDX,IDC_SENTIFIC,m_sentitic);//}}AFX_DATA_MAP}BEGIN_MESSAGE_MAP(CCalculatorDlg,CDialog)//{{AFX_MSG_MAP(CCalculatorDlg)ON_WM_SYSCOMMANDOON_WM_PAINT()ON_WM_QUERYDRAGICON()ON_COMMAND_RANGE(IDC_0,IDC_9,OnOperandlnput)ON_BN_CLICKED(IDC_ADD,OnAdd)ON_BN_CLICKED(IDC_MINUS,OnMinus)ON_BN_CLICKED(IDC_DIVID,OnDivid)ON_BN_CLICKED(IDC_MULTIPLY,OnMultiply)ON_BN_CLICKED(IDC_EQUAL,OnEqual)ON_BN_CLICKED(IDC_SQRT,OnSqrt)ON_BN_CLICKED(IDC_SIGN,OnSign)ON_BN_CLICKED(IDC_RECIPROCAL,OnReciprocal)ON_BN_CLICKED(IDC_POINT,OnPoint)ON_BN_CLICKED(IDC_CLEAR,OnClear)ON_BN_CLICKED(IDC_LOG,OnLog)ON_BN_CLICKED(IDC_LN,OnLn)ON_BN_CLICKED(IDC_FACTORIAL,OnFactorial)ON_BN_CLICKED(IDC_EXP,OnExp)ON_BN_CLICKED(IDC_SENTIFIC,OnSentific)ON_BN_CLICKED(IDC_SIN,OnSin)ON_BN_CLICKED(IDC_SQUAR,OnSquar)ON_BN_CLICKED(IDC_TAN,OnTan)ON_BN_CLICKED(IDC_STANDARD,OnStandard)ON_BN_CLICKED(IDC_DEGREE,OnDegree)ON_BN_CLICKED(IDC_RAD,OnRad)ON_BN_CLICKED(IDC_COS,OnCos)//}}AFX_MSG_MAPEND_MESSAGE_MAP()IICCalculatorDlgmessagehandlersBOOLCCalculatorDlg::OnInitDialog(){CDialog::OnInitDialog();//Add”About...”menuitemtosystemmenu.//IDM_ABOUTBOXmustbeinthesystemcommandrange.ASSERT((IDM_ABOUTBOX&OxFFFO)==EDM.ABOUTBOX);ASSERT(IDM_ABOUTBOX<OxFOOO);CMenu*pSysMenu=GetSystemMenu(FALSE);if(pSysMenu!=NULL){CStringstrAboutMenu;strAboutMenu.Loadstring(IDS_ABOUTBOX);if(!strAboutMenu.IsEmptyO){pSysMenu->AppendMenu(MF_SEPARATOR);pSysMenu・>AppendMenu(MF_STRING,IDM_ABOUTBOX,strAboutMenu);}}//Settheiconforthisdialog.Theframeworkdoesthisautomatically//whentheapplication'smainwindowisnotadialogSetlcon(m_hlcon,TRUE);
