当我们听到电脑上出现美妙的旋律的时候，是不是发现这是一个很伟大的开发，这就是C语言中函数Beep，下面武林技术频道小编就给大家介绍C++中发声函数Beep用法。

下面是正文：

•其实啊，Windows API 就提供了一个这样奇妙的发音函数，它就是Beep函数。Beep可以通过控制主板扬声器的发声频率和节拍来演奏美妙的旋律，本文根据音乐简谱来演奏几首优美的歌曲，用以展现Beep的疯狂魅力。

首先我们来Beep的函数原型：

BOOL Beep(  DWORD dwFreq;   DWORD dwDuration;);

参数说明：

•dwFreq 指定要发出的频率(HZ)
•dwDuration 指定发音的时长，以毫秒为单位。

Beep的实际应用

•比如说我要发do这个音，do应该是523hz，且如果要发一拍的话，就相当于400毫秒。
•那这个函数就成了这样：Beep(523,400);

•但是，如果我们要连续的发出多个音的话，比如说像这样：

Beep(523,400);//do Beep(578,400);//re Beep(659,400);//mi

•那岂不是太麻烦了，所以，我建议大家用define函数宏定义一下这些音，比如说这样：#define re 578和#define mi 659，这样，上面的三行语句就简化了成这样：

Beep(do,400);Beep(re,400);Beep(mi,400);

最终，给亲们送上一份表（借别人的划去)
其中，q前缀为低音，1后缀为高音，s前缀为半音阶

#define qdo 262 #define qre 294#define qmi 330#define qfa 349#define qso 392#define qla 440#define qsi 494#define do 523#define re 578#define mi 659#define fa 698#define so 784#define la 880#define si 988#define do1 1046#define re1 1175#define mi1 1318#define fa1 1480#define so1 1568#define la1 1760#define si1 1976#define sqdo 277#define sqre 311#define sqfa 370#define sqso 415#define sqla 466#define sdo 554#define sre 622#define sfa 740#define sso 831#define sla 932#define sdo1 1046#define sre1 1245#define sfa1 1480#define sso1 1661#define sla1 1865

最后，（嘿，同志们，别跑，后面还有彩蛋呢！）

好吧，是一首用Beep函数演奏的天空之城
