四楼大哥的回答的 我改了 。。 三楼大哥的建议我也试了， 可是 最后的 output 执行不了。。。。 楼下两位大哥 我不能评论 点赞 发图 新的回复也不行。。只能编辑这个旧的回复 ////三楼的大哥 我用代码片上传了代码。。 然后我现在 main 那里output 方面 没有打印

struct book先定义在作为返回值使用，4-8行应该放在2-3行之前。另外请你重新发一下代码，这个太乱了。
//把
void struct BOOK output(struct Book book);
//改成
void output(struct Book book)
#include"stdio.h"
struct Book {
char name[100] ;
int money;
char author[100] ;
};
struct Book getInput(struct Book *book);
void output(struct Book book);
struct Book getInput(struct Book *book)
{
printf("请输入书名:");
scanf("%s", &book->name);
printf("请输入售价:");
scanf("%d", &book->money);
printf("请输入作者:");
scanf("%s", &book->author);
return *book;
}
void output(struct Book book)
