C语言课程设计-购物卡管理系统

一、题目要求系统主要功能模块：1实现系统内制卡，发卡功能。实现系统内购物卡帐户及相关帐户管理。实现购物卡交易和合法性检查。实现购物卡交易积分功能。实现购物卡报表功能。数据以文件形式存储。提示：制卡：指申请一个购物卡，但还没有使用。发卡：指该卡已经起用。实现卡交易：指从卡中消费掉一定金额。二、需求分析根据题目要求,由于购物卡信息是存放在文件中,所以应提供文件的输入、输出等操作；在程序中需浏览购物卡的信息,应提供报表、查询等操作；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,可以将系统分为五大模块：制卡、发卡、登陆、报表、积分。四、详细设计1、主函数将main()函数体内的界面选择部分语句单独抽取出来作为一独立函数，目的在于系统执行完每部分功能模块后能够方便返回到系统界面。voidmenu()
