C语言课程设计报告—客房管理系统

1、报告正文、题目要求客户信息包括身份证号、性别、年龄、房间号。试设计一客房管理系统，使之 能提供以下功能：1系统以菜单方式工作2客户信息录入功能客户信息用文件保存3客户信息统计功能4客户信息查询功能，查询方式5客户信息修改功能可选项提示建立客户信息结构体，结构体成员包括身份证号、性别、年龄、房间号、需求分析根据题目要求，要求对客户信息进行输入、输出等操作；在程序中需要浏览客户 的信息，应提供显示、统计、查询、修改等操作；另外还应提供键盘式选择菜单实现 功能选择。三、总体设计根据需求分析，可以对这个系统的设计分为以下几个模块:数据查询数据修改数据删除系统功能模块图四、详细设计1、主函数局部:主函数

2、一般设计得比拟简洁，只提供输入，处理和输出局部的函数调用。其中各 功能模块用菜单方式选择。流程图:显示各功能选项1FN输入n ,判t断 n是否是0-5Y根据n的值调用各功能模块函数主函数流程图main()/* 主函数 */、竹、prin店管理系printf("nnntttPress any key to continue.");printf("nnnnnnnnnnnntttttttt-By黄李 n");getch();menu();void regist()/* 注册函数 */int n,m,i,j;printf("tHow many new
