C語言課程設(shè)計報告-手機(jī)通訊錄管理系統(tǒng)

C程序課程設(shè)計報告--通訊錄管理系統(tǒng)姓名:謝駿學(xué)院:珠寶學(xué)院學(xué)號:20231002649班級:141082一課程設(shè)計目的和內(nèi)容概述1.目的：加深對《C語言》課程所學(xué)知識的理解，進(jìn)一步穩(wěn)固C語言編程方法。學(xué)會編制結(jié)構(gòu)清晰、風(fēng)格良好、數(shù)據(jù)結(jié)構(gòu)適當(dāng)?shù)腃語言程序，從而具備解決綜合性實際問題的能力，加強(qiáng)動手能力。2.內(nèi)容：設(shè)計一個簡易的通訊錄管理系統(tǒng)。該題目要求在熟練掌握C語言的根本知識：數(shù)據(jù)類型〔整形、實型、字符型、指針、數(shù)組、結(jié)構(gòu)等〕；運(yùn)算類型〔算術(shù)運(yùn)算、邏輯運(yùn)算、自增自減運(yùn)算、賦值運(yùn)算等〕；程序結(jié)構(gòu)〔順序結(jié)構(gòu)、判斷選擇結(jié)構(gòu)、循環(huán)結(jié)構(gòu)〕；大程序的功能分解方法〔即函數(shù)的使用〕等。進(jìn)一步掌握各種函數(shù)的應(yīng)用，包括時間函數(shù)、、繪圖函數(shù)，以及文件的讀寫操作等。其中結(jié)構(gòu)體，函數(shù)的調(diào)用，算法的設(shè)計是尤為重要的。二題目通訊錄管理系統(tǒng)。[問題描述]

該系統(tǒng)模擬通訊錄管理系統(tǒng),實現(xiàn)對中的通訊錄進(jìn)行管理

[根本要求]

要能提供以下幾種功能:

(1)查看功能:選擇此功能時,列出以下三類選擇：

A:辦公類

B:個人類

C:商務(wù)類

(2)中選中某類時,顯示出此類所有數(shù)據(jù)中的姓名和號碼

(3)添加數(shù)據(jù)功能:能錄入新數(shù)據(jù),每個結(jié)點包括:姓名,號碼,分類(可能選項有:w為辦公類p為個人類b為商務(wù)類),電子郵件。。

(5)刪除功能：選中某個人的姓名時，可對此人的相應(yīng)數(shù)據(jù)進(jìn)行刪除，并自動調(diào)整后續(xù)條目的編號。三程序設(shè)計1.總體設(shè)計首先，因為每個個體有多種信息，所以要建立結(jié)構(gòu)體來儲存和整合各個信息。然后利用模塊來分別實現(xiàn)程序的各個功能。各個模塊用函數(shù)來實現(xiàn)。在通過通過主函數(shù)來判斷輸入字母，從而調(diào)動函數(shù)，實現(xiàn)所需功能。最后將輸入的文件保存在文件里，以便重復(fù)使用。2.詳細(xì)設(shè)計根據(jù)功能需要建立顯示，添加，查看，刪除，修改，保存五個模塊。在模塊中通過調(diào)用各個函數(shù)來實現(xiàn)功能。詳細(xì)設(shè)計如下：〔1〕構(gòu)建結(jié)構(gòu)體，寫入文件FILE*fp;inti;structaddress{chara[40];//email地址};structffriend{intnum;charname[20];charkind[20];longtelephone;structaddressaddress;}friends[50];voidLoad(){intj;longk;fp=fopen("friend.txt","a+");//翻開文件friend.txtif(fp!=NULL){for(i=1;i<50;i++){j=fgetc(fp);if(j==EOF)//判斷是否到了文件尾return;k=i-1;fseek(fp,k*sizeof(structffriend),SEEK_SET);fread(&friends[i],sizeof(structffriend),1,fp);//從文件中讀取一條記錄}}else{fp=fopen("friend.txt","w");i=1;}〔2〕構(gòu)造函數(shù)與模塊構(gòu)造顯示模塊，增加模塊，刪除模塊，修改模塊，查詢模塊。程序如下：voidShow(intj){system("cls");//實現(xiàn)分屏操作的函數(shù)printf("\n\n\t編號-Nnumber:%3d",friends[j].num);printf("\n\t姓名-Name:%-20s",friends[j].name);printf("\n\t性別-kind:%s",friends[j].kind);printf("\n\t聯(lián)系-Telephone:%-13ld",friends[j].telephone);printf("\n\temail-address:%-40s",friends[j].address.a);}voidAppend(intj){system("cls");friends[j].num=j;printf("\n\t\t\t序號-Number:%d",j);printf("\n\t\t\t姓名-Name:");scanf("%s",friends[j].name);printf("\t\t\t類別-kind:");scanf("%s",&friends[j].kind);printf("\t\t\t聯(lián)系-telephone:");scanf("%ld",&friends[j].telephone);{printf("號碼不合法!請重新輸入:");scanf("%ld",&friends[j].telephone);}printf("\t\t\temail-Address:");scanf("%s",friends[j].address.a);getchar();}voidDelete(){intk;intj;system("cls");printf("\n\tDelete序號-Number:");scanf("%d",&k);if(k<=i){for(j=k;j<i+1;j++)/*插入位置后的元素順序后移*/{strcpy(friends[j].name,friends[j+1].name);/*交換元素內(nèi)容*/strcpy(friends[j].kind,friends[j+1].kind);friends[j].telephone=friends[j+1].telephone;strcpy(friends[j].address.a,friends[j+1].address.a);}i--;}else{printf("輸入的序號太大!");}}voidModify(intj){system("cls");Append(j);}voidSave(){inti,j;system("cls");printf("\n\n\t\t請耐心等待,信息正在保存!\n");printf("\n\n\n\n\t\t\tSaving");for(i=0;i<20;i++){Sleep(300);printf(".");}printf("\n\n信息已經(jīng)保存成功!\n");fp=fopen("friend.txt","w");for(j=1;j<=i;j++){fwrite(&friends[j],sizeof(structffriend),1,fp);}fclose(fp);}〔3〕主函數(shù)調(diào)用各個模塊用switch語句判斷輸入者要使用的功能，然后調(diào)用函數(shù)，模塊實現(xiàn)功能。程序如下：voidmain(){intj;chara;charx;chargrade;charsearchkind[20];
