電子詞典程序開發(fā)一、需求分析〔1〕程序的功能英漢詞典作為一個常用的學(xué)習(xí)工具，是我們經(jīng)常要使用的。該系統(tǒng)能完成一個簡單的電子英漢詞典的功能，如：單詞的查找、增詞、刪除、修改和維護(hù)等工作。在計算機(jī)中建立有限規(guī)模的電子英漢詞典〔文件〕，利用程序?qū)崿F(xiàn)電子英漢詞典的查找、增詞、刪除、修改和維護(hù)工作。詞典的容為：每行對應(yīng)一個詞條，每個詞條由兩個字符串組成，字符串用假設(shè)干空格符分開；前一個是單詞字符串〔英文〕，后一個是釋義字符串〔中文〕，使用分號作為多個釋義的分隔符〔無空格〕。對單詞和釋義字符串長度的限定分別為不少于10個與15個字符，詞條數(shù)限定為不多于1000條?！?〕輸入輸出的要求。采用菜單工作方式。在一個操作執(zhí)行之后，程序詢問是否繼續(xù)執(zhí)行該操作。如輸入Y或y，那么重復(fù)同一操作，不退回到菜單；如輸入其它信息，那么回到菜單等待另一次選擇。僅中選擇退出操作時，程序應(yīng)詢問是否將修改后的詞典存盤，并根據(jù)用戶選擇存盤退出或不存盤退出。要求整個設(shè)計以人為本，用戶界面友好。二、總體設(shè)計】、程序共有五個子函數(shù)和一個主函數(shù)。search是查找函數(shù)，用戶通過系統(tǒng)提示輸入要查找的單詞，只要單詞庫中含有此單詞便能找到相應(yīng)的中文解釋。這個查找函數(shù)使用的是從頭到尾的線性查找發(fā)，雖然查找效率在數(shù)據(jù)很大上午時候無法容忍的。但是因為這里涉及的數(shù)據(jù)量很小，使用線性查找對系統(tǒng)性能沒有很大上午損害。add是增加函數(shù)，用戶可通過此函數(shù)來增加單詞庫單詞的數(shù)量。modify是修改函數(shù)，程序提示用戶輸入要修改的單詞，還是用線性查找的方法查找相應(yīng)的紀(jì)錄，如果找到，那么提示輸入新單詞及中文解釋。delete是刪除函數(shù)，程序提示用戶輸入要刪除的單詞，使用線性查找的方法找到相應(yīng)的紀(jì)錄，如果找到，提示用戶確認(rèn)刪除才做。在得到確認(rèn)后，刪除這個單詞的紀(jì)錄。主程序通過無限循環(huán)來接收輸入的命令，并且根據(jù)命令調(diào)用相應(yīng)的函數(shù)處理。2、課題中涉及到的數(shù)字主要是英文單詞，和數(shù)據(jù)1-4，它們都屬于字符型數(shù)據(jù)，它們的結(jié)果還應(yīng)該是字符型。三：詳細(xì)設(shè)計11=1f1f2!1if輸入單詞查*強(qiáng)項輸入詞性輸入音標(biāo)輸入中立輸入信息顯示defaultir循環(huán)體1f?計宣41f俺環(huán)缽1fL計算—*日f盾環(huán)缽1f1計篁—*日廠結(jié)束fL1f四、調(diào)試分析與設(shè)計體會：1、輸入1就是添加新的單詞，輸入2是刪除已有的單詞，輸入3是查找要找的單詞，它包括兩種方法，1：是輸入英語找單詞，2：是輸入漢語找單詞，輸入4是退出程序。2、感教師讓我有時機(jī)再次學(xué)習(xí)C語言.我們這次設(shè)計的課題是電子英漢詞典的設(shè)計，通過這次的程序設(shè)計，知道了自己以前在學(xué)習(xí)C語言方面的缺乏，光是書本上的知識是不夠的，自己編寫出程序也是學(xué)習(xí)過程中相當(dāng)重要的一環(huán)，以前學(xué)習(xí)過程中出現(xiàn)的問題在這次課題設(shè)計中全都暴露出來.例如:對知識的掌握不牢，程序的理解不透徹等等.所以，我不得不再翻開課本以鞏固以前學(xué)過的知識，這讓我有效的彌補(bǔ)了知識的漏洞.一開場我就對C語言很感興趣。我覺得每每聽完一堂課，我都有一種說不出的快樂，有時也會發(fā)愁，因為課程越往后越難學(xué)而且講課進(jìn)度再加快，但我沒有退縮，每天堅持看C語言。就這樣一步步走到課程設(shè)計。雖然在這個實(shí)習(xí)周里的語言設(shè)計遇到了很多困難，但我并沒有退縮，找同學(xué)教師幫著改正錯誤，終于完成了，使自己嘗到了成功的甜頭。希望學(xué)校繼續(xù)給我們這樣的學(xué)習(xí)時機(jī)。五、參考文獻(xiàn)：《C語言程序設(shè)計》主編譚浩強(qiáng)清華大學(xué)2005年7月《C語言程序設(shè)計實(shí)驗指導(dǎo)與習(xí)題解答》主編譚浩強(qiáng)清華大學(xué)2005年7月《計算機(jī)軟件根底》主編麥中凡苗明川何玉潔高等教育2007年3月六、原程序設(shè)計清單：#include<stdio.h>#include<string.h>main(){staticintn=32；charm；struct{chareng[10]；charci[15]；charyin[10]；charchi[30]；}word[1000]={{"good","a","goud","hao"},{"aide","n","eid","zhushou"},{"bone","n","boun","gutou"},{"ball”,"n”,"bo：”,"qiu"},{"cat","n","cat","mao"},{"cattle","n","katl","niu"},{"clean","adj+d+v","kli：n","1.ganjin2.gongzheng"},{"a","num","ei","yige"},{"finally","ad","fai'nens","zuizhong"},{"finish","v+n","finish","wancheng"},{"girl","n","ge:l","nvhai"},{"five”,"v”,”giv”,"gei"},{"go”,"n+v”,"gou”,"zou"},{"help","int+n","help","bangzhu"},{"he","pron","hi:","ta"},{"here","ad+ini","hie","zheli"},{"high","aadj+ad+n","hai","gao"},{"ice","n","ais","bing"},{"idea","n","ai'die","zhuyi"},{"imagine","v","i'madgin","xiangxiang"},{in,v,in:,zailimian},{"kill”,"v”,”kil”,"shasi"},{"king","n","king","guowang"},{"kiss","v+n","kis","wen"},{"knight","n+v","nait","qishi"},{"late","adj+ad","leit","1.chide2.yihoude"},{"left","adj+ad+n","left","zuobian"},{"line","n+v","lain","xian"},{"name","n+v","neim","mingzi"},{mission,v,mision,rengwu}};clrscr();loop:for(；；){clrscr()；printf("\n\t****Pleasemakeachoise****\n")；printf("\n\n\tl.Addthenewword\n")；printf("\t2.Delword\n")；printf("\t3.findword\n")；printf("\t4.Exittheprocess\n\n")；printf("Pleasechoose1~4toenter\n")；printf("Pleasepressthekey:")；scanf("%c",&m)；switch(m){case'1':{charj[10],k[15],l[10],p[30]；++n；printf("\nAddnewword")；printf("\n\npleaseentertheDanci:")；scanf("%s",j)；printf("\nEntertheCixing:")；scanf("%s",k)；printf("\nEntertheYingbiao:")；scanf("%s",l)；printf("\nEntertheChinese:")；scanf("%s",p)；strcpy(word[n].eng,j)；strcpy(word[n].ci,k)；strcpy(word[n].yin,l)；strcpy(word[n].chi,p)；printf("\nPleasecheckit:")；printf("\n\nEnglish.%s",word[n].eng)；printf("\n\nCixing：%s",word[n].ci)；printf("\n\nYinbiao:%s",word[n].yin);printf("\n\nChinese:%s\n\n",word[n].chi);printf("\nPleasepressanykeywithEnterkeyback!");scanf("%s",m);}gotoloop;case'2':{charr[10];ints,t,u,z=0,x=0;printf("PleasepresstheEnglishyouwanttodel:");scanf("%s",r);for(s=0;s<=n;s++){if(s<=n-1){if(strcmp(word[s].eng,r)==0){x=1;for(t=s;t<n;t++){strcpy(word[t].eng,word[t+1].eng);strcpy(word[t].ci,word[t+1].ci);strcpy(word[t].yin,word[t+1].yin);strcpy(word[t].chi,word[t+1].chi);}}else{if(strcmp(word[n].eng,r)==0)z=1；elsez=0;}}if(z==1||x==1){printf("\n\nDelsucessful!!\n");n——;printf("\nPleasepressanykeywithEnterkeyback!");scanf("%s",m);}else{printf("\n\nDelfailed!!");printf("\nPleasepressanykeywithEnterkeyback!");scanf("%s",m);}}break;case'3'：{intl；clrscr()；printf("\n\nSearchtheword\n")；printf("1.SearchbyEnglish:\n");printf("2.SearchbyChinese:\n");printf("Otherkeyback\n");printf("Pleasechooseone:");scanf("%d",&l);switch(l){case1:{charr[10],m[1];ints;printf("\nPleaseentertheEnglishword:");scanf("%s",r);for(s=0;s<=n;s++){if(s<=n-1)if(strcmp(word[s].eng,r)==0)break;elsecontinue;elseif(strcmp(word[n].eng,r)==0)break;else{charm[1];printf("\nNothisword!!\nPleasepressanykeywithEnterkeyback!")；scanf("%s",m)；gotoloop;}}printf("\
