用windowsAPI自带的Beep函数实现《千本樱》，由于Beep函数调用系统蜂鸣器，非常耗CPU性能，会导致发音不稳定，博主偶然发现通过手动调节系统音量可以缓解卡顿。
代码如下：
#include<iostream>
#include<windows.h>
#include <utilapiset.h>
#include <process.h>
using namespace std;
#define qdo 262
#define qre 294
#define qmi 330 //q前缀为低音，1后缀为高音，s前缀为半音阶
#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
