基于C++的车辆信息管理系统方案

理工大学软件学院课程实践报告课程设计 C++课程实践题目车辆信息管理班级软件15-7学生 ***学号 ***指导教师 ***管理系统的功能说明1．存储数据的描述2．概要设计说明书3．源程序4．测试分析（用户操作手册）5．总结报告1.管理系统功能说明车辆管理系统有五项功能：一.增加车辆信息二.浏览所有的车辆信息三.查询车辆信息（按车辆品牌和型号）四.修改车辆信息（通过型号查找再修改）五.退出系统2.存储数据的描述由于本学期c++关于类的知识学的不精，我定义的是上学期学习的结构体，并利用文件存储fopen与fclose产生一个名为information的txt文件存储数据，方便程序的读写。
