要求：
服装销售系统的功能是完成服装信息（服装代码、型号、规格、面料、颜色、单价、数量）先曾、修改和查找功能及服装销售信息（服装代码、数量、日期、售价、小计）登记和查找功能。销售服装时相应的服装信息数量要进行修改（比如原来有100件，销售了50件后只能剩余50件）。
提示：
（1） 用两个文件存放服装信息和销售信息；
（2） 定义结构体表示服装信息和销售信息；
（3） 打印系统操作菜单：N.服装信息登记；M.服装信息修改；D.服装信息删除；S.服装销售登记；Q.退出系统。
答案：闲着无聊，就帮你写个呗。功能：N.服装信息登记；M.服装信息修改；D.服装信息删除；S.服装销售登记；Q.退出系统。
