c++制作的“音樂計時器”，結束后播放《天空之城》-有解無憂

tips：這個程式我還做了一個下載的

這個計時器好像是全站為數不多的結束后有聲音提醒的計時器，類似于秒表

我做的這個計時器，主要用到的函式是Sleep()，Sleep函式的頭檔案是windows.h

先介紹一下這個函式的用處：

Sleep函式可以使計算機程式（行程，任務或執行緒）進入休眠，簡單來說就是讓程式停止作業一個特定時間，單位是毫秒，比如：

#include <iostream>
#include <windows.h>
#include <time.h>
using namespace std;
int main(){
    cout << "程式開始" << endl;
    clock_t start = clock();
    clock_t end;
    Sleep(2000);
    end = clock();
    cout << "Sleep(2000)這個函式執行了" << (end - start) / 1000 << "秒";
    return 0;
}

上圖是運行結果

然后要讓電腦演奏音樂，要用Beep()函式，音樂就是《天空之城》

Beep函式的頭檔案依舊是windows.h

Beep()函式有兩個引數一個是音高，另一個時長，第二個單位同樣是毫秒，第一個我就不知道了，不過要一次一次這樣反復的寫還是相當麻煩的，所以可以把每個音都改成宏變數，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，在高我就不寫了，其他音都列在下面的代碼里了

#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

接下來，要注意一下音樂中間的休止符和每個音符的長度，我就都設定8分(好像是)音符是400毫秒，停頓是128毫秒

下面是天空之城的演奏音樂

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，就是計時器的制作了：

（1）做到每秒輸出一次，不會受回圈控制

要做到這一點，就要用到之前說的Sleep()函式，每過1秒，就回圈1次，回圈的計算時間基本可以忽略不計，每次回圈Seconds--就行了

這一步的代碼段如下

void CountDown_Seconds(int &Days,int &Hours,int &Mintues,int &Seconds){
    for(;Seconds >= 0;Seconds--){
        cout << "倒計" << Days << "" << Hours << "" << Mintues << "" << Seconds << "秒" << endl;
        Sleep(1000);
        system("cls");
    }
}

（2）分鐘計時

每分鐘這個就直接每次回圈呼叫CountDown_Seconds函式就可以了，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;
    }
}

同樣，小時和天也一樣，不停呼叫分鐘和小時就可以了，這兩步就放在一起了：

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;
    }
}

剩下的就是輸入部分了

void printMenu(){
    cout << "歡迎進入間倒計系統"<<endl;
    cout << endl;
}
void Input(){
    cout<<"請輸入時間：格式：天 時 分 秒"<<endl;
    cin >> days >> hours >> mintues >> seconds;
    cout << endl;
}
