1、軟件基礎(chǔ)課程設(shè)計(jì)報(bào)告 一、需求分析系統(tǒng)目標(biāo)：設(shè)計(jì)的計(jì)算器至少能夠進(jìn)行簡(jiǎn)單的四則運(yùn)算和求倒數(shù)求反以及開(kāi)方運(yùn)算。主體功能：程序能實(shí)現(xiàn)：加，減，乘，除，開(kāi)方，倒數(shù)等運(yùn)算功能；還要實(shí)現(xiàn)數(shù)據(jù)的輸入，輸出，計(jì)算，顯示及程序退出等功能。另外還可以實(shí)現(xiàn)多種科學(xué)計(jì)算的功能，如：三角函數(shù)的計(jì)算，弧度與角度間的轉(zhuǎn)換，對(duì)數(shù)指數(shù)的計(jì)算等。開(kāi)發(fā)環(huán)境：操作系統(tǒng)：windows xp編程環(huán)境：microsoftvisualc+6.0 二、功能說(shuō)明(1)包含的功能有：加、減、乘、除運(yùn)算，開(kāi)方、求倒數(shù)、三角函數(shù)、弧度與角度間的轉(zhuǎn)換、對(duì)數(shù)指數(shù)的計(jì)算等功能。(2)計(jì)算器上數(shù)字09為一個(gè)控件數(shù)組，加、減、乘、除為一個(gè)控件數(shù)組，其余為單

2、一的控件。(3)給對(duì)話(huà)框添加菜單。(4)計(jì)算功能基本上是用系統(tǒng)內(nèi)部函數(shù)。(5)程序可以能自動(dòng)判斷輸入數(shù)據(jù)的正確性，保證不出現(xiàn)多于一個(gè)小數(shù)點(diǎn)、以0開(kāi)頭等不正?，F(xiàn)象。(6)“ce”按鈕可以清除所有已輸入的數(shù)據(jù)從頭計(jì)算，“back”按鈕可以實(shí)現(xiàn)退位功能。（7）能夠顯示時(shí)間、日期。三、詳細(xì)設(shè)計(jì)（1）流程圖創(chuàng)建工程（創(chuàng)建一個(gè)對(duì)話(huà)框應(yīng)用程序）設(shè)計(jì)對(duì)話(huà)框界面設(shè)置各控件屬性為編輯框連接成員變量為類(lèi)添加數(shù)據(jù)成員，初始化構(gòu)造函數(shù)。為所有按鈕添加事件對(duì)類(lèi)添加成員函數(shù)（更新編輯框）并進(jìn)行實(shí)現(xiàn)實(shí)現(xiàn)對(duì)各按鈕事件的實(shí)現(xiàn)（2）編輯資源（3）效果圖四、程序附錄計(jì)算器dlg.cpp :#include stdafx.h#incl
