班级通信录管理系统(汇编课程设计).doc

1、 班级通信录管理系统1 需求说明1.1实验要求1.1.1建立通讯录，添加一个同学的通信记录，删除一个同学的通信记录，修改一个同学的通信记录，查询一个同学的通信记录，显示所有同学的通信记录，能根据姓名或宿舍号进行排序。1.1.2通信记录包括学号、姓名、电话号码、宿舍号等信息，所有信息最终用文件保存。1.2功能简述1.2.1 建立通信录运行程序后，程序自动建立固有的通讯录。1.2.2添加通信记录 进入“添加界面，根据提示，依次添加同学的通信记录条目。添加成功，后显示操作成功信息。1.2.3删除通信记录进入“删除界面，依据姓名删除信息。输入姓名后，显示该同学的所有信息，并显示操作成功。删除后，返回主

2、菜单。1.2.4查询通信记录 进入“查询界面，询问用户按姓名或学号查找学生记录。待用户正确输入已存有的用户姓名或学号后，按回车键后显示所有匹配该信息的学生记录。若输入信息错误或是无该用户没记录，则显示操作错误。1.2.5显示所有通信记录 进入“显示界面，将通讯录中所有同学的通讯记录分行显示出来，每行中同学的不同信息间隔表示。1.2.6根据姓名进行排序排序时，显示排序子菜单，按照姓名中字母的升序对记录进行排序。1.2.7保存通讯记录 将填写好的同学通讯记录写入到固定文件中。1.2.8退出班级通信录管理系统 选择该功能选项后，退出班级通信录管理系统，关闭文件，返回DOS。2设计说明2.1 程序流程

3、图设计 入口 主界面 选择功能 Select Insert Modify Delete Write Show Esc 退出系统 显示所有记录 写入文件 删除界面 查询界面 添加界面 修改界面 Back 结束2.2各功能之间的关系2.2.1用户输入信息在选择Insert选项后，进入adder子程序，需要用户依次输入姓名、学号、宿舍号、电话号码，输入信息分别存入manelist、studlist、dormlist、telelist数组中。2.2.2搜索同学记录建立selectbyname和selectbystud子程序，在select子程序中灵活调用，利用相关信息搜索与关键字匹配的同学记录。同时，

4、可以把搜索这个功能提取出来，实现代码的共享。其中，搜索按关键字的类型不同可分为按姓名搜索和按学号搜索。2.2.3关键字的匹配selectbyname和selectbystud子程序中都需要进行关键字匹配和比较，故把比较关键字的大小提取出来在strCmp子程序中实现，方便进行搜索和排序。2.3文档的处理在用户进入班级通信录管理系统时，若要将输入的信息用文件保存，用户可选择Write to file选项，将缓冲区和文档中的所有记录显示出来。用户退出后，关闭文件。3详细的算法设计3.1主程序的设计start: mov ax,data mov ds,ax mov es,ax call cshdata

11、学记录，若查找不到，则修改失败。否则提示用户输入新的通讯信息，覆盖原来的信息。3.6按照姓名进行排序Sort函数采用冒泡排序作为算法进行排序，内外循环次数均为同学通讯录记录的条数，由于字符串的交换比较复杂，则将此子过程抽象出来，记为movR函数。使用loop循环依次交换两个记录的字符。3.7删除操作的实现删除数据信息，查询条件为姓名。删除查询结果的具体做法是：先搜索到与关键字匹配的记录，然后用最后一个记录将其覆盖，达到删除的效果。.3.8与文件相关的操作3.8.1创建文件 filename db F:StudentList.txt,00h handle dw ? buffer db 20 du
