音乐播放器程序源代码及注释: #include
需求分析 1引言 随着社会的快速发展，现今社会生活紧张，而欣赏音乐是其中最好的舒缓压力的方式之一，音乐成了我们生活工作中的一个重要的部分。而计算机的普及，让人们能让我们通过播放软件，能更好的听到我们喜欢的音乐。本文档就是为了能更好的设计出一个音乐播放去而编写的。 1.1编写目的： 为明确软件需求、安排项目与进度、组织软件开发与测试，撰写本文档。本文档功项目经理、设计人员、开发人员参考。 1.2项目背景项目背景项目背景项目背景 本项目由老师提出，由学生自主开发，实现播放现今主流的音乐MP3，wma文本格式。 开发软件名称：音乐播放器 项目开发者：岳世崇 1.3项目目的和目标 本项目的目的是开发一个可以播放主流的音乐文本格式，本设计的实现主要功能是播放MP3，wma 格式的音乐文件，并且能控制播放，暂停，停止，音量控制，选择上一曲，选择下一曲，各种播放模式，视觉外观，列表文件等多种播放控制，界面简明，操作简单。 1.4参考资料 百度文库，mci接口调用方法
c语言程序设计——清华大学出版社 c数据结构——清华大学出版社。 2.系统需求分析 根据项目，我们可以获得项目系统的基本需求，一下从不同角度来描述系统的需求。 2.1功能需求 系统的功能需求，我们分成三部分来概括，即播放器的基本控制需求，播放列表管理需求和播放器友好性需求。以下分别描述： 一：播放器的基本控制需求 （1）播放：选择歌曲进行播放。 （2）暂停：输入暂停对应的选项，播放暂停。 （3）继续播放：输入继续播放对应的选项，实现继续播放。 （4）停止播放：输入停止播放对应的选项，实现停止播放。 （5）音量控制：输入音量控制所对应的选项实现音量控制。 （6）上一首，下一首：输入上一首或者下一首对应的选项实现歌曲的切换。 （7）播放模式：列表循环播放，列表顺序播放，随机播放，单曲循环播放，单曲播放的选项，选择播放模式。 （8）删除歌曲：删除列表中不想出现的歌曲 （9）快进/快退：输入相应的选项进入快进和快退功能并实现。 （10）查看文件大小：输入查看文件的大小对应的选项，实现查看文件大小的功能 （11）列表之间的相互切换，可以选择不同路径下的不同播放列表 。 二：播放列表管理 1.添加歌曲：添加歌曲的时候可以在本播放列表下进行添加，也可以选择输入播放列
