c++|c++制作的“音乐计时器”，结束后播放《天空之城》 sqlite|小程序|ios

tips：这个程序我还做了一个下载的
【c++|c++制作的“音乐计时器”，结束后播放《天空之城》】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

#include #include using namespace std; #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 int days; int hours; int mintues; int seconds int main(){ int pai = 400,ban = 200; int ting = 128; Sleep(1000); Beep(la,ban); Beep(si,ban); Sleep(ting); Beep(do1,pai + ban); Beep(si,ban); Sleep(ting); Beep(do1,pai); Sleep(ting); Beep(mi1,pai); Sleep(ting); Beep(si,3 * pai); Sleep(ting); Beep(mi,ban); Beep(mi,ban); Beep(la,ban + pai); Beep(so,ban); Sleep(ting); Beep(la,pai); Sleep(ting); Beep(do1,pai); Sleep(ting); Beep(so,2 * pai); Sleep(ting); Sleep(pai); Beep(mi,ban); Sleep(ting / 2); Beep(mi,ban); Sleep(ting / 2); Beep(fa,pai + ban); Beep(mi,ban); Sleep(ting); Beep(fa,ban); Beep(do1,ban + pai); Sleep(ting); Beep(mi,2 * pai); Sleep(ting); Sleep(ban); Beep(do1,ban); Sleep(ting / 2); Beep(do1,ban); Sleep(ting / 2); Beep(do1,ban); Sleep(ting / 2); Beep(si,ban + pai); Beep(sfa,ban); Sleep(ting); Beep(sfa,pai); Beep(si,pai); Sleep(ting); Beep(si,2 * pai); Sleep(ting); Sleep(pai); //只有1遍 return 0; }

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; }

最后附上完整代码：
