结构体指针
#include<stdio.h>void printBook(struct Book book);
struct BookgetInput(struct Book book);
struct Date
{
int year;
int month;
int day;
};
struct Book
{
char title;
char author;
float price;
struct Date date;
char publisher;
};
struct BookgetInput(struct Book book)
{
printf("请输入书名：");
scanf("%s",book.title);
printf("请输入作者：");
scanf("%s",book.author);
printf("请输入价格：");
scanf("%f",&book.price);
printf("请输入出版日期：");
scanf("%d-%d-%d",&book.date.year,&book.date.month,&book.date.day);
printf("请输入出版社：");
scanf("%s",book.publisher);
return book;
}
void printBook(struct Book book)
{
printf("书名：%s\n",book.title);
printf("作者：%s\n",book.author);
printf("售价：%.2f\n",book.price);
printf("出版日期：%d-%d-%d\n",book.date.year,book.date.month,book.date.day);
printf("出版社：%s\n",book.publisher);
}
int main(void)
{
struct Book b1,b2;
printf("请录入第一本书的信息...\n");
b1=getInput(b1);
putchar('\n');
printf("请录入第二本书的信息...\n");
b2=getInput(b2);
putchar('\n');
printf("录入完毕,现在开始打印验证") ;
printf("打印第一本书的信息...");
printBook(b1);
putchar('\n');
printf("打印第二本的信息");
printBook(b2);
return 0;
} 我想问下为什么我用DEV-C++无法执行语句 哪一步错了呢 变量 b1, b2 沒有初始化
