#week15-1_PlaySound

1. 原來程式碼改
2. ```cpp
   #include <windows.h>
   
   ```cpp
   int main(...)
   {
        PlaySound("C:/mykbeat.wav",NULL,SND_ASYNC);
   }```
3. 改程式碼
1. PlaySound("C:/Do.wav",NULL,SND_SYNC);
2.     PlaySound("C:/Re.wav",NULL,SND_SYNC);
3.     PlaySound("C:/Mi.wav",NULL,SND_SYNC);
4.     PlaySound("C:/Fa.wav",NULL,SND_SYNC);
5.     PlaySound("C:/Sol.wav",NULL,SND_SYNC);
6.     PlaySound("C:/mykbeat.wav",NULL,SND_ASYNC);
4. 程式碼:

   3.  * GLUT Shapes Demo
   4.  *
   5.  * Written by Nigel Stewart November 2003
   6.  *
   7.  * This program is test harness for the sphere, cone
   8.  * and torus shapes in GLUT.
   9.  *
   10.  * Spinning wireframe and smooth shaded shapes are
   11.  * displayed until the ESC or q key is pressed.  The
   12.  * number of geometry stacks and slices can be adjusted
   13.  * using the + and - keys.

12. 在main()裡
```cpp
