C++中发声函数Beep用法

•以前，我听过一个神�挠�C++函数做的音乐，当时的心里就十分激动：哇，好厉害啊，好神啊。

•这次，我终于通过自己无助的盲目的摸索、研究，写出了这篇文章（此时我的内心是鸡冻的233）

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
