《面向程序設(shè)計》MFC計算器

1、 面向程序設(shè)計實訓(xùn)報告專 業(yè)： 學(xué)生姓名： 學(xué) 號： 指導(dǎo)教師： 2011年6月 29日面向程序設(shè)計實訓(xùn)報告1、實訓(xùn)項目：設(shè)計一個基于對話框的計算器，實現(xiàn)常用計算器的基本功能。2、性能、指標、要求；1、基本要求(1) 按照題目要求獨立設(shè)計計算器所需的所有按鈕，并完成程序源碼編寫、調(diào)試及關(guān)鍵代碼注釋。（2）能夠?qū)崿F(xiàn)+、-、*、/計算。 （3）能夠?qū)崿F(xiàn)對數(shù)及冪函數(shù)計算。 （4）能夠?qū)崿F(xiàn)三角函數(shù)及反三角函數(shù)計算。 2、發(fā)揮部分 能夠?qū)崿F(xiàn)8，16，10，2進制之間相互轉(zhuǎn)換。 3、方案設(shè)計： 方案論證 通過運行VC6.0，用MFC制作windows風(fēng)格的界面的計算器 工作原理 1、啟動VC+6.0, 從

2、File菜單中選擇New選項, 選擇Projects標簽，然后單擊MFCAppWizard(exe)。2、在Location域中輸入一個合適的路徑名或單擊Browse按鈕來選擇一個。在Project name中輸入項目名稱（比如：0952100407）。點OK。3、打開MFC AppWizard-Step1對話框后。選擇基本對話。點下一個 。4、在MFC AppWizard-Step2 of 4對話框。 輸入標題對話，如：計算器。點下一個。5、在MFC AppWizard-Step3 of 4對話框。不做任何更改，直接點下一個。6、在MFC AppWizard-Step4 of 4對話框?？梢?/p>

3、修改分類名等信息，在這里不做任何更改，直接點完成。至此進入了界面設(shè)計過程。4、軟件設(shè)計 進入界面設(shè)計界面后，利用右側(cè)的控件欄添加按鈕，在按鈕屬性中修改按鍵的顯示，雙擊按鍵進入按鍵的程序設(shè)計。制作完成后的界面如下所示：5、制作與調(diào)試過程； 雙擊按鈕后進入程序設(shè)計過程，每個按鈕的程序如下所示：/ 0952100407Dlg.cpp : implementation file/#include stdafx.h#include 0952100407.h#include 0952100407Dlg.h#include cmath#ifdef _DEBUG#define new DEBUG_NEW#un
