【文档】C语言程序设计----通讯录

一、设计任务书1）复习、巩固C语言的基础知识，进一步加深对C语言的理解和掌握；2）课程设计为学生提供了一个既动手又动脑，独立实践的机会，将课本上的理论知识和实际有机的结合起来，锻炼学生的分析解决实际问题的能力。

提高学生适应实际，实践编程的能力；3）培养学生在项目开发中团队合作精神、创新意识及能力。

4）对系统进行功能模块分析、控制模块分析正确，符合课题要求，实现相应功能；可以加以其他功能或修饰，使程序更加完善、合理；二、本组课题设计一个通讯录管理系统三、程序功能简介该程序具有添加、查找，修改、删除通讯录中各个成员所有信息的功能。

四、主体内容1、设计分析1.1问题提出本人计划编写一个通讯录管理系统，主要用来记录和管理所有联系人的详细联系方式1.2本系统涉及的知识点本系统涉及到所学过的知识点有：编译预处理，函数，循环结构，循环结构，数组，结构体，指针，文件等1.3功能要求1、制作一个通讯录程序，要求可以记录联系人的详细联系方式，包括：姓名，联系电话，居住地所在省份，城市，街道，以及当地邮编2、能根据需要随时在通讯录中添加联系人3、能根据联系人的名字查找他的详细联系方式4、能根据需要修改某联系人的联系方式5、能删除某特定联系人的所有联系方式2、程序结构流程图这里只附部分模块流程图：（1）系统的界面如图1所示（下图）图1 系统的菜单选项2.2、删除模块流程图：如图(2)图(2)删除模块流程图3．各模块的功能及程序说明3.1各模块的功能：* Main模块：根据选单内容实现调用函数* Delete模块：删除通讯录中某人的信息，其程序如下* list模块：显示通讯录中的所有记录3.2程序说明：（1）Main函数/******主函数开始*******/main(){int i;person p[M];int length; /*保存记录长度*/clrscr();/*清屏*/for(;;)/*无限循环*/{switch(menu())()) /*调用主菜单函数，返回值整数作开关语句的条件*/{case 0:length=create(p);break;case 1:list(p,length);break; /*显示全部记录*/case 2:search(p,length);break; /*查找记录*/case 3:length=delete(p,length);break; /*删除记录*/case 4:length=add(p,length); break; /*插入记录*/case 5:exit(0); /*如返回值为5则程序结束*/}}}（2） Delete函数/*删除函数，参数为记录数组和记录条数*/int delete(person t[],int n){char s[20]; /*要删除记录的姓名*/int ch=0;int i,j;printf("please deleted name\n"); /*提示信息*/scanf("%s",s); /*输入姓名*/i=find(t,n,s); /*调用find函数*/if(i>n-1) /*如果i>n-1超过了数组的长度*/printf("no found not deleted\n"); /*显示没找到要删除的记录*/ else{print(t[i]); /*调用输出函数显示该条记录信息*/printf("Are you sure delete it(1/0)\n"); /*确认是否要删除*/scanf("%d",&ch); /*输入一个整数0或1*/if(ch==1) /*如果确认删除整数为1*/{for(j=i+1;j<n;j++) /*删除该记录，实际后续记录前移*/{strcpy(t[j-1].name,t[j].name); /*将后一条记录的姓名拷贝到前一条*/strcpy(t[j-1].units,t[j].units); /*将后一条记录的单位拷贝到前一条*/strcpy(t[j-1].tele,t[j].tele); /*将后一条记录的电话拷贝到前一条*/strcpy(t[j-1].street,t[j].street); /*将后一条记录的街道拷贝到前一条*/strcpy(t[j-1].city,t[j].city); /*将后一条记录的城市拷贝到前一条*/strcpy(t[j-1].provience,t[j].provience); /*将后一条记录的省份拷贝到前一条*/strcpy(t[j-1].num,t[j].num); /*将后一条记录的邮编拷贝到前一条*/}n--; /*记录数减1*/}}return n; /*返回记录数*/}（3）List函数/*显示记录，参数为记录数组和记录条数*/void list(person t[],int n){int i;clrscr();printf("\n\n*******************ADDRESS******************\n");printf("name unit telephone street city provience num\n");printf("------------------------------------------------\n");for(i=0;i<n;i++)printf("%-20s%-30s%-10s%-20s%-20s%-20s%-20s\n",t[i].name,t[i].units,t[i].tele,t[i].street,t[i].city,t[i].provience,t[i].num);if((i+1)%10==0) /*判断输出是否达到10条记录*/{printf("Press any key continue...\n"); /*提示信息*/getch();/*压任意键继续*/}printf("************************end*******************\n");}4、试验结果『含输入数据和输出结果』通过很多次的实验，本程序（源程序在程序清单中）终于可以正常运行，任何一项功能都能顺利实现5、设计体会以前不曾做过课程设计，因此在做课程设计时遇到了很大的困难，首先是在编写程序时，用的时间很长，并且经过多次运行都不能成功。
