基于MFC的面向對象多功能計算器設計

1、基于MFC的面向對象多功能計算器設計一、需求分析1、設計背景計算器是日常生活中十分便捷有效的工具，計算器大大的降低了數(shù)字計算的難度及提高了計算的準確度和精確度。但是目前很多計算器的功能過于簡單化，精確度也不高。本次設計的基于MFC的VC+面向對象多功能計算器，實現(xiàn)了功能的多樣化，使用非常簡單和方便，增加了使用者的選擇性，應用范圍大為提高，更加符合現(xiàn)在社會使用者的要求。2、計算器功能系統(tǒng)具有良好的界面；必要的交互信息；簡約美觀的效果。使用人員能快捷簡單地進行操作。即可單機按鈕進行操作，也可直接通過鍵盤直接輸入。即時準確地獲得需要的計算的結果，充分降低了數(shù)字計算的難度和節(jié)約了時間.該計算器不但功能

2、上比一般的計算器多很多，而且精度上也提高了不少。根據(jù)目前的背景分析所知道的社會需求以及本人平時在課堂上蔣老師所講的知識，參考相關資料，本次設計所實現(xiàn)的功能：1) 一般計算機所具有的加、減、乘、除、開方、清零功能2) 進行二進制、八進制、十進制、十六進制之間的轉換3) 有退格功能4) 進行度數(shù)和弧度的Sin 、arcSin 、Cos、 arcCos 、Cot 、arcCot 、Tan 、arcTan運算5) 進行xy x2 x3運算6) 進行l(wèi)n log運算7) 輸出結果的精確度為小數(shù)點后六位8） 程序可以能自動判斷輸入數(shù)據(jù)的正確性和操作數(shù)據(jù)的正確性，若有錯去會提醒。二、概要設計1. 設計基礎M

3、icrosoft Visual C+提供了利用MFC編寫程序的方法，這大大提高了軟件的開發(fā)，提高編程的效率。MFC提供了大量預定義的類和支持代碼，可以處理許多標準Windows編程任務，如生成窗口和處理消息，加入各種復雜的特性，如工具欄、OLE支持、Active控件非常的方便和高效。本次軟件即是基于MFC進行設計，基于MFC庫類進行對對話框界面的設計，通過創(chuàng)建類成員函數(shù)成員變量，編輯控件創(chuàng)建消息映射，調用消息函數(shù)完成數(shù)據(jù)的輸入輸出，實現(xiàn)計算功能。使用C+，在VC下進行編寫。2. 軟件主體框架 總體設計思路流程圖如圖1 圖1 計算器總體設計思路流程圖3、 詳細設計1、程序流程及解釋1.1 圖2為
