Question

error: syntax error before '{' token不知道怎么改

这是我的代码
#include"stdio.h"
int main()
{
struct date
{
int year;
int month;
int day;
};

struct song
{
char title[64];
char artist[37];
int time;
struct date published;
};
struct song song1={"红豆","王菲",180,{2013,03,20}};
printf={"song1所有信息：歌名：%s\n 歌手%s\n 播放时间%s\n 出版时间%d年%d月%d日\n",song1.title,song1.artist,song1.time,
song1.published.year,song1.published.month,song1.published.day};
return 0;
}
求助~

Answer 1

你又好几个问题呢，一是printf后不能加=号，二不能使用大括号要使用小括号,三打出播放时间你用的不能是%s要用%d因为时间是整型，修改后程序如下
#include"stdio.h"

int main()
{
struct date
{
int year;
int month;
int day;
};

struct song
{
char title[64];
char artist[37];
int time;
struct date published;
};
struct song song1={"红豆","王菲",180,{2013,03,20}};

printf("song1所有信息：歌名：%s\n 歌手%s\n 播放时间%d\n 出版时间%d年%d月%d日\n",song1.title,song1.artist
,song1.time,song1.published.year,song1.published.month,song1.published.day);

return 0;
}

太谢谢了，正常运行了

Answer 2

大括号前有语法错误printf();

追问

改成（）以后又报新的错了
就是printf的下一行
error: invalid lvalue in assignment|

 printf("song1所有信息：歌名：%s\n 歌手%s\n 播放时间%s\n 出版时间%d年%d月%d日\n",song1.title,song1.artist,song1.time,
song1.published.year,song1.published.month,song1.published.day);
应该是参数类型不兼容 
也就是%s对应的要是兼容的类型
