假设同目录中有a.wav这个文件.
(本程序是由<C游戏从入门到高手>这本书的一段代码,目的是播放背景音乐.音乐播放的时

问题就是:程序运行没有效果,请问各位大侠应该如何修改呢?

请各位高手教教我这个大一的小学生啊
 
请各位帮帮忙啊
 
好象是用Pc喇叭演奏呀!~?
Testsb();
PlayWavBg(); //播放?
while(!kbhit())
printf("."); //按任意键推出
fclose(fp);
RestoreTimer();



void PlayWavBg()
{

Counter=1;
fseek(fp,44L,0);
if(wfhead.wbpsam==16)
num=num/2;
SetTimer(NewTimer,44100);
}
是不是源码有问题
