文件： 别让我担心.rar - 蓝奏云 (lanzoub.com)
视频版：【C++】爆肝527行只为这首《别让我担心》！_哔哩哔哩_bilibili
接下来正式开始教学

  1. 普普通通的头文件&框架
#include <bits/stdc++.h>
#include <windows.h>
using namespace std;
int main()
{
	
	return 0;
}

不要忘记#include <windows.h>
否则Beep函数和Sleep函数都会报错

  1. 音高赋值
    在Beep函数中，音高的单位是赫兹
    但是几乎每个音的音高（单位用赫兹）都是浮点数，你总不能每次打一长串浮点数吧
    所以有了如下的改进方法
	h[360]=440.0;
	int cnt=110;
	for(int i=0;i<=128;i++){
		if(cnt/10%10==8){
			cnt+=30;
			continue;
		}
		if(cnt%100==35||cnt%100==75){
			cnt+=5;
			continue;
		}
		h[cnt]=(h[360]/32.0)*pow(2,(i-9.0)/12.0);
		//cout<<cnt<<" "<<h[cnt]<<"\n";
		cnt+=5;
	}

i的界限可以随便定（当然别超过int类型的范围）
cnt用来遍历h数组的下标
h数组的下标是音高
个位表示是否为半音
对，就是你（不太）经常看到的‘#’号（划掉）
但是，3-mi和7-si没有半音，所以就cnt+=5然后continue掉
十位分别表示do re mi fa sol la si，然而我们用的是十进制，所以当便历到80时cnt+=30再continue掉就好了
百位：一般的曲子最高音最低音至少会差一个八度，这个百位用来记录八度，具体记录第几个八度没有硬性要求
其他：h[360]=440.0 这是整数，方便计算
h[cnt]=(h[360]/32.0)*pow(2,(i-9.0)/12.0); 频率计算公式，这个与乐理有关，在C++论坛上就不多说了哈（可以问度娘）
注释部分可用于调试，可对照下面这幅图

  1. 重点-演奏部分
	Beep(114,514);

Beep函数，后接两个参数，第一个表示音高，单位是赫兹，后一个表示音长，单位是毫秒，在代码中充当音符
上述代码运行时，将会发出一个高114赫兹，长514毫秒的音

	Sleep(1919.810);

Sleep函数，后接一个参数，表示停止的时长，单位是毫秒，在代码中充当休止符
上述代码运行时，将会停止1919.810毫秒
懂得这两个函数后，你就可以找到简谱/五线谱，一个一个对着音符/休止符写代码了（当然具体音符/休止符的时长计算我不教，因为这是C++论坛啊喂）
还有，一个四分音符的音长=60/速度*1000
并不具体的代码：

	Beep(h[310],a);
	Beep(h[320],a);
	Beep(h[330],a);
	Beep(h[340],a);
	Beep(h[350],a);
	Beep(h[360],a);
	Beep(h[370],a);
	Beep(h[410],a);
	Sleep(a);
	Beep(h[410],a);
	Beep(h[370],a);
	Beep(h[360],a);
	Beep(h[350],a);
	Beep(h[340],a);
	Beep(h[330],a);
	Beep(h[320],a);
	Beep(h[310],a*2);

当然如果你想做一整首曲子的话肯定有优化方法，但只适用于伴奏或纯音乐
一般一整首音乐可分为A1段 B1段……
然后A1段再现了！
通俗点说，就是写几个函数，有重复出现的乐段就调用
框架就像这样：

#include <bits/stdc++.h>
#include <windows.h>
using namespace std;
void A1(){
	//...
}
void B1(){
	//...
}
int main()
{
	A1();
	B1();
	return 0;
}

4.细节增加
比如在演奏前输出作者等信息（建议用Sleep函数等待一两秒）
和输出每一句的歌词
如果你写了下面两行代码：

	ios::sync_with_stdio(0);
	cin.tie(0),cout.tie(0);

关流可能会导致歌词输出与乐句演奏不同步，如果出现上述情况要删掉
以上。
