1.播放音檔(有問題找上週)
#include <stdio.h>
#include <windows.h>
int main()
{
printf("playsound()之前\n"); (等待)
PlaySound("07071104.wav",NULL,SND_SYNC);
printf("playsound()之後\n");
}
# ASYNC 不等待，不會播放
除非下一行非"Sound"
winmm 可以播放聲音?
SYNC+ASYNC =不用 winmm
2. SYNC(等待)、ASYNC(不等待)
#include <stdio.h>
#include <windows.h>
int main()
{
PlaySound("07071104.wav",NULL,SND_ASYNC);
while(1)
{
printf("請輸入數字: ");
int n;
scanf("%d",&n);
if(n==1) PlaySound("do.wav",NULL,SND_ASYNC);
if(n==2) PlaySound("re.wav",NULL,SND_ASYNC);
if(n==3) PlaySound("mi.wav",NULL,SND_ASYNC);
}
}
ASYNC => 邊執行while邊撥放、播放中可讀數字
SYNC => 先撥放再執行while、撥放完才能讀，但會記得你按過什麼數字
1-3 mp3
# wav能直接讀，mp3有壓縮過，要再多加程式
#include "CMP3_MCI.h" moodle下載
#include <stdio.h>
CMP3_MCI mp3;///宣告變數
int main()
{
mp3.Load("Hurry_Up.mp3");
mp3.Play();
printf("請輸入數字: ");
int n; 讀數使音樂停止播放
scanf("%d",&n);
}
1-4 4個動作
S鍵儲存座標，存4個複製到file.txt，最後Build按r重現儲存位置
(It work this time)
