这两天才发现程老师建的网站，也想来凑凑热闹，增加点人气！（嘿嘿） 一时没想好留点什么在上面，后看程老师贴个音名音符号频率对照表，于是想起写个小程序给它变的智能点（呵呵 其实也没多大用 就是写着玩的），顺便也练习一下我那荒废已久的C语言（不写不知道啊，发现都忘差不多！）先写这么多吧，我写的程序如果还可以优化的话或是还有什么问题的话 大家多留言 多发贴 让程老师的这里人兵兴盛 呵呵！

注：Windows下用什么
Turbo C 之类的编译一下就行，苹果下在终端下输入＄gcc -o xxx xxx.c(如果你安装了xcord集成开发工具的话 就有gcc了)，其他类Unix操作系统都同苹果终端下一样（如果安装了gcc）
