班级通信录系统汇编课程设计

1、班级通信录管理系统1需求说明1.1实验要求lolo1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。l.lo2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lo2。1建立通信录运行程序后，程序自动建立固有的通讯录。lo2.2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。lo2.3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，返回主菜单.

2、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。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。lo2.8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程序流程图设计Back2各

3、功能之间的关系2o2.1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、donnlist、telelist数组中。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: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。2o3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

4、字的大小提取出来在stiCmp子程序中实现，方便进行搜索和排序。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Writetofile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详细的算法设计主程序的设计start：movaxJatamovds.axmoves.axcallcshdatamenu1:callclearcalldisplaytitlemovah,Olhint21hcmpal,Tjzselcmpal,2jzaddecmpal/3，jzmodicmpal/4，jzdelcmpal,5jzdiscmpal,7jzwrtcmpal,

10、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.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。.3o8与文件相关的操作。1创建文件filenamedb，F:StudentListotxt*,00hhandledw?bufferdb20dup(0)error1dbcreatingfilewrong!0dh,0ah.$error2db，writingfilewrong!,0dh,0ah。$wrtstrdb,writetheclassaddressbook!$mov
