C语言课程设计报告

C语言课程设计论文学生姓名：陈丹 学生学号：101所在班级：信息和计算科学一班任课老师：马老师通讯录管理系统【设计目标】设计“通讯录管理系统”使其含有数据插入、修改、删除、显示和查询等功效。数据包含：人名、工作单位、电话号码和E-mail地址。可对统计中姓名和电话号码进行修改。可增加或删除统计。可显示全部保留统计。可按人名或电话号码进行查询。【设计思绪】依据要求，电话簿数据以文本文件存放在文件中，故需要提供文件输入、输出等操作；还需要保留统计以进行修改，删除，查找等操作；另外还应提供键盘式选择菜单实现功效选择。【总体设计】通讯录管理系统通讯录管理系统数据输入数据修改删除数据添加查找浏览图1系统功效模块图【具体设计】主函数主函数设计要求简练，只提供部分提醒语和函数调用【程序】显示一系列功效选项显示一系列功效选项输入n，判定n是否是1~7？依据n值调用各功效模块函数结束开始n图2.主函数步骤图Voidmenu()/*主界面*/{intn,w1;voidenter();voidadd();voidmodify();voidbrowse();voiddeleter();voidsearch();do{puts("\t******************************菜单*****************************\t\n\n");puts("\t\t\t\t1.新建联络人");puts("\t\t\t\t2.添加联络人");puts("\t\t\t\t3.修改");puts("\t\t\t\t4.删除");puts("\t\t\t\t5.浏览");puts("\t\t\t\t6.查找");puts("\t\t\t\t7.退出");puts("\n\n\t***************************通讯录******************************\t\n");printf("请选择服务种类(1-7):[]\b\b");scanf("%d",&n);if(n<1||n>7){w1=1;getchar();}elsew1=0;}while(w1==1);switch(n){case1:enter();break;/*输入模块*/case2:add();break;/*添加模块*/附录：源代码#defineN50#include<stdio.h>#include<string.h>structpeople{charname[20];charcompany[50];charnum[15];charmail[20];}peop[N];voidprintf_face(){printf("\n\t姓名\t单位\t电话号码\t邮箱\n");}voidprintf_one(inti){printf("\t%s\t%s\t%s\t%s\n",peop[i].name,peop[i].company,peop[i].num,peop[i].mail);}voidprintf_n(intn){intj;for(j=0;j<n;j++){if((j!=0)&&(j%10==0)){printf("\n\nPressanykeytocontinue...:");getchar();puts("\n\n");}printf_one(j);}getchar();}intload(){FILE*fp;inti;if((fp=fopen("file","rb"))==NULL){printf("\nCannotopenfile\n");exit(0);}for(i=0;!feof(fp);i++)fread(&peop[i],sizeof(structpeople),1,fp);fclose(fp);return(i-1);}intmodify_data(inti,intn){intc,w1;voidinput(inti);voidmenu();do{puts("\n修改选项=>\n\n1).姓名2).单位3).电话号码4).邮箱5).全部数据6).取消并返回");printf("请选择?:[]\b\b");scanf("%d",&c);if(c>6||c<1){puts("\nChooseerror!Pleaseagain!");getchar();}}while(c>6||c<1);do{switch(c){case1:printf("name:");scanf("%s",peop[i].name);break;case2:printf("company:");scanf("%s",peop[i].company);break;case3:printf("number:");scanf("%s",peop[i].num);break;case4:printf("e-mail:");scanf("%s",peop[i].mail);break;case5:input(i);break;
