基于MFC的面向?qū)ο蠖喙δ苡?jì)算器設(shè)計(jì)

1、基于MFC的面向?qū)ο蠖喙δ苡?jì)算器設(shè)計(jì)一、需求分析1、設(shè)計(jì)背景計(jì)算器是日常生活中十分便捷有效的工具，計(jì)算器大大的降低了數(shù)字計(jì)算的難度及提高了計(jì)算的準(zhǔn)確度和精確度。但是目前很多計(jì)算器的功能過于簡(jiǎn)單化，精確度也不高。本次設(shè)計(jì)的基于MFC的VC+面向?qū)ο蠖喙δ苡?jì)算器，實(shí)現(xiàn)了功能的多樣化，使用非常簡(jiǎn)單和方便，增加了使用者的選擇性，應(yīng)用范圍大為提高，更加符合現(xiàn)在社會(huì)使用者的要求。2、計(jì)算器功能系統(tǒng)具有良好的界面；必要的交互信息；簡(jiǎn)約美觀的效果。使用人員能快捷簡(jiǎn)單地進(jìn)行操作。即可單機(jī)按鈕進(jìn)行操作，也可直接通過鍵盤直接輸入。即時(shí)準(zhǔn)確地獲得需要的計(jì)算的結(jié)果，充分降低了數(shù)字計(jì)算的難度和節(jié)約了時(shí)間.該計(jì)算器不但功能

2、上比一般的計(jì)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(huì)需求以及本人平時(shí)在課堂上蔣老師所講的知識(shí)，參考相關(guān)資料，本次設(shè)計(jì)所實(shí)現(xiàn)的功能：1) 一般計(jì)算機(jī)所具有的加、減、乘、除、開方、清零功能2) 進(jìn)行二進(jìn)制、八進(jìn)制、十進(jìn)制、十六進(jìn)制之間的轉(zhuǎn)換3) 有退格功能4) 進(jìn)行度數(shù)和弧度的Sin 、arcSin 、Cos、 arcCos 、Cot 、arcCot 、Tan 、arcTan運(yùn)算5) 進(jìn)行xy x2 x3運(yùn)算6) 進(jìn)行l(wèi)n log運(yùn)算7) 輸出結(jié)果的精確度為小數(shù)點(diǎn)后六位8） 程序可以能自動(dòng)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(cuò)去會(huì)提醒。二、概要設(shè)計(jì)1. 設(shè)計(jì)基礎(chǔ)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(yù)定義的類和支持代碼，可以處理許多標(biāo)準(zhǔn)Windows編程任務(wù)，如生成窗口和處理消息，加入各種復(fù)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(jìn)行設(shè)計(jì)，基于MFC庫(kù)類進(jìn)行對(duì)對(duì)話框界面的設(shè)計(jì)，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(diào)用消息函數(shù)完成數(shù)據(jù)的輸入輸出，實(shí)現(xiàn)計(jì)算功能。使用C+，在VC下進(jìn)行編寫。2. 軟件主體框架 總體設(shè)計(jì)思路流程圖如圖1 圖1 計(jì)算器總體設(shè)計(jì)思路流程圖3、 詳細(xì)設(shè)計(jì)1、程序流程及解釋1.1 圖2為
