用C语言做一个可以播放音乐的八音盒
1、//声明部分
#include<stdio.h>
#include<windows.h>
#define LENTH 300//音长标准
struct music
{
unsigned tune;//音调
unsigned tone;//音色
unsigned hold;//音长
};
typedef struct music* song;//结构体指针
static int size;//静态变量
void init(song S,int *I);//初始化结构体
void play(song S);//播放歌曲
int record(void);//曲目
void play_adv(song S);//高级播放
song test(void);//测试歌曲
song test_adv(void);//测试歌曲-高级
song happy(void);//欢乐颂
song star_adv(void);//小星星-高级
2、//主函数部分
int main()
{
char c;
printf("*******曲目********\n"
"[1].欢乐颂\n"
"[2].小星星\n"
"[0].测试音调\n"
"******************\n");
do{
printf("\n");
switch(record())//曲目选择
{
case 1: puts("--欢乐颂--"); play(happy());break;
case 2: puts("--小星星--"); play_adv(star_adv());break;
case 0: puts("--测试发声器--"); play(test());break;
default: puts("--高级测试发音--"); play_adv(test_adv());
}
printf("要继续吗(q退出)?");
c=getch();//自动获取输入
}while(c!='q');
puts("\n--结束--\n");
return 0;
}
3、void init(song S,int *I)//初始化结构
