c++计算器（多个）

======================================================================== MICROSOFT FOUNDATION CLASS LIBRARY : 计算器 ======================================================================== AppWizard has created this 计算器 application for you. This application not only demonstrates the basics of using the Microsoft Foundation classes but is also a starting point for writing your application. This file contains a summary of what you will find in each of the files that make up your 计算器 application. 计算器.dsp This file (the project file) contains information at the project level and is used to build a single project or subproject. Other users can share the project (.dsp) file, but they should export the makefiles locally. 计算器.h This is the main header file for the application. It includes other project specific headers (including Resource.h) and declares the CMyApp application class. 计算器.cpp This is the main application source file that contains the application class CMyApp. 计算器.rc This is a listing of all of the Microsoft Windows resources that the program uses. It includes the icons, bitmaps, and cursors that are stored in the RES subdirectory. This file can be directly edited in Microsoft Visual C++. 计算器.clw This file contains information used by ClassWizard to edit existing classes or add new classes. ClassWizard also uses this file to store information needed to create and edit message maps and dialog data maps and to create prototype member functions. res\计算器.ico This is an icon file, which is used as the application's icon. This icon is included by the main resource file 计算器.rc. res\计算器.rc2 This file contains resources that are not edited by Microsoft Visual C++. You should place all resources not editable by the resource editor in this file. ///////////////////////////////////////////////////////////////////////////// For the main frame window: MainFrm.h, MainFrm.cpp These files contain the frame class CMainFrame, which is derived from CFrameWnd and controls all SDI frame features. res\Toolbar.bmp This bitmap file is used to create tiled images for the toolbar. The initial toolbar and status bar are constructed in the CMainFrame class. Edit this toolbar bitmap using the resource editor, and update the IDR_MAINFRAME TOOLBAR array in 计算器.rc to add toolbar buttons. ///////////////////////////////////////////////////////////////////////////// AppWizard creates one document type and one view: 计算器Doc.h, 计算器Doc.cpp - the document These files contain your CMyDoc class. Edit these files to add your special document data and to implement file saving and loading (via CMyDoc::Serialize). 计算器View.h, 计算器View.cpp - the view of the document These files contain your CMyView class. CMyView objects are used to view CMyDoc objects. ///////////////////////////////////////////////////////////////////////////// Other standard files: StdAfx.h, StdAfx.cpp These files are used to build a precompiled header (PCH) file named 计算器.pch and a precompiled types file named StdAfx.obj. Resource.h This is the standard header file, which defines new resource IDs. Microsoft Visual C++ reads and updates this file. ///////////////////////////////////////////////////////////////////////////// Other notes: AppWizard uses "TODO:" to indicate parts of the source code you should add to or customize. If your application uses MFC in a shared DLL, and your application is in a language other than the operating system's current language, you will need to copy the corresponding localized resources MFC42XXX.DLL from the Microsoft Visual C++ CD-ROM onto the system or system32 directory, and rename it to be MFCLOC.DLL. ("XXX" stands for the language abbreviation. For example, MFC42DEU.DLL contains resources translated to German.) If you don't do this, some of the UI elements of your application will remain in the language of the operating system. /////////////////////////////////////////////////////////////////////////////
