这篇博客介绍了如何利用C++和Windows头文件windows.h中的Beep函数来创建简单的音乐程序。通过定义不同音符对应的频率，结合不同的持续时间，可以播放出简单的旋律。示例代码演示了如何用Beep方法播放一段旋律。

C++的windows.h里有一个Beep方法，这个方法调用系统蜂鸣器，发出特定频率的声音。

参数如下：

windows.h Beep方法
参数名	类型	是否必须	说明
dwFreq	DWORD	是	发出声音的频率
dwDuration	DWORD	是	发出声音的长度（毫秒）

先给大家放出音调对应频率的#define语句~

把这段程序敲到自己电脑里，听听是哪首歌吧！
