c++制作的“音乐计时器”，结束后播放《天空之城》
tips：这个程序我还做了一个下载的
这个计时器好像是全站为数不多的结束后有声音提醒的计时器，类似于秒表
我做的这个计时器，主要用到的函数是Sleep()，Sleep函数的头文件是windows.h
先介绍一下这个函数的用处：
Sleep函数可以使计算机程序（进程，任务或线程）进入休眠，简单来说就是让程序停止工作一个特定时间，单位是毫秒，比如：
#include
#include
#include
using namespace std;
int main(){
cout << "程序开始" << endl;
clock_t start = clock();
clock_t end;
Sleep(2000);
end = clock();
cout << "Sleep(2000)这个函数执行了" << (end - start) / 1000 << "秒";
return 0;
} 
上图是运行结果
然后要让电脑演奏音乐，要用Beep()函数，音乐就是《天空之城》
Beep函数的头文件依旧是windows.h
Beep()函数有两个参数一个是音高，另一个时长，第二个单位同样是毫秒，第一个我就不知道了，不过要一次一次这样反复的写还是相当麻烦的，所以可以把每个音都改成宏变量，就能方便不少，低音do是262，低音re是294，低音fa是330，低音fa是349，低音so是392，低音la是440，低音si是494，do是523，re是578，mi是659，fa是698，so是784，la是880，si是988，在高我就不写了，其他音都列在下面的代码里了
#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接下来，要注意一下音乐中间的休止符和每个音符的长度，我就都设置8分(好像是)音符是400毫秒，停顿是128毫秒
下面是天空之城的演奏音乐

} 然后，就是计时器的制作了：
（1）做到每秒输出一次，不会受循环控制
要做到这一点，就要用到之前说的Sleep()函数，每过1秒，就循环1次，循环的计算时间基本可以忽略不计，每次循环Seconds--就行了
这一步的代码段如下
void CountDown_Seconds(int &Days,int &Hours,int &Mintues,int &Seconds){
for(;Seconds >= 0;Seconds--){
cout << "倒计" << Days << "" << Hours << "" << Mintues << "" << Seconds << "秒" << endl;
Sleep(1000);
system("cls");
}
}（2）分钟计时
每分钟这个就直接每次循环调用CountDown_Seconds函数就可以了，每次60秒后把Seconds
改成59就可以了
void CountDown_Mintues(int &Days,int &Hours,int &Mintues,int &Seconds){
for (;Mintues >= 0;Mintues--){
CountDown_Seconds(Days,Hours,Mintues,Seconds);
Seconds = 59;
}
}同样，小时和天也一样，不停调用分钟和小时就可以了，这两步就放在一起了：
void CountDown_Hours(int &Days,int &Hours,int &Mintues,int &Seconds){
for (;Hours >= 0;Hours--){
CountDown_Mintues(Days,Hours,Mintues,Seconds);
Mintues = 59;
}
}
void CountDown(int Days,int Hours,int Mintues,int Seconds){
for(;Days >= 0;Days--){
CountDown_Hours(Days,Hours,Mintues,Seconds);
Hours = 23;
}
}剩下的就是输入部分了
void printMenu(){
cout << "欢迎进入间倒计系统"<> days >> hours >> mintues >> seconds;
cout << endl;
