c语言乐曲演奏——《千本樱》

这个程序着实花费了我好长的时间，我本身对音乐一窍不通，先是跟着girl friend学习了简谱，根据c调44拍的《千本樱》写下了下面的程序。

  1 #include<stdio.h>
  2 #include<dos.h>
  3 void mysound(unsigned int freq,int times)
  4 {
  5     int i;
  6     union
  7     {
  8         int divisor;
  9         char c[2];
 10     } count;
 11     char bits;
 12     count.divisor=1193180/freq;
 13     outportb(0x43,0xb6);
 14     outportb(0x42,count.c[0]);
 15     outportb(0x42,count.c[1]);
 16     bits=inportb(0x61);
 17     outportb(0x61,bits|3);
 18     for(i=0; i<times; i++)
 19         delay(120);
 20     outport(0x61,bits&0xfc);
 21     outportb(0x61,bits);
 22 }
 23 int main()
 24 {
 25     int freq[8]= {0,256,294,330,349,392,440,494};
 26     int song[]= {5,6,2,1,2,1,5,6,2,1,2,1,
