编译能通过---------- 编译时把注释去掉
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
struct song{ //定义一个歌曲结构
int id; //歌曲号
char title[20]; //歌曲名
char singer[20]; //歌手名
};
typedef struct song SONG; //把结构命名为 SONG
int main( void )
{
SONG songlist[100]; //定义一个存储歌曲信息的列表，长100
int i=0,j;
int c;
clrscr();
while (i<=100) {
printf( "please enter the song's id, title and singer:\n" );
//输入歌曲号 然后空格 输入歌曲名 然后空格 输入歌手名 然后回车
scanf( "%d%s%s", &songlist[i].id, songlist[i].title, songlist[i].singer);
i++;
//每次输入完一条信息后，把列表中的歌曲信息全部打印出来看一下
printf("the songlist is below:\n\n");
for( j=0; j<=i; j++){
printf( "%d %s %s\n", songlist[j].id, songlist[j].title, songlist[j].singer );
}
printf("\n");
}
getch();
return 0;
}
或者是
#include "dos.h"
#include "stdio.h"
#define time 10000 /*预定义节拍长度 time（一拍）*/
#define time0 5000 /*预定义半节拍长度 time0*/
#define time1 15000 /*预定义1.5节拍长度 time1*/
#define time2 20000 /*预定义2节拍长度 time2*/
#define time3 30000 /*预定义3节拍长度 time3*/
#define _a 262 /*预定义低音音符1～7*/
#define _b 294
#define _c 330
#define _d 349
#define _e 392
#define _f 440
#define _g 494
#define a 523/*预定义中音音符1～7*/
#define b 587
#define c 659
#define d 698
#define e 784
#define f 880
#define g 988
#define a_ 1047/*预定义高音音符1～7*/
#define b_ 1175
#define c_ 1319
