求结构体数组指针构建图书馆管理系统的程序
感谢 楼主越来越懒了，以前写了那么多结构数组的代码练习，自己拼凑个大概还做不到吗？ 我的数组元素是结构体，而不是结构体指针，怎么改成结构体指针呢{:9_241:}#include <stdio.h>#include <stdlib.h>
struct Date
{
int year;
int month;
int day;
};
struct Book
{
char title;
char author;
float price;
struct Date date;
char publisher;
};
void getInput(struct Book *);
void printBook(struct Book *);
void getInput(struct Book *book)
{
printf("title: ");
scanf("%s", book->title);
printf("author: ");
scanf("%s", book->author);
printf("price: ");
scanf("%f", &book->price);
printf("date: ");
scanf("%d-%d-%d", &book->date.year, &book->date.month, &book->date.day);
printf("publisher: ");
scanf("%s", book->publisher);
}
void printBook(struct Book *book)
{
printf("title: %s\n", book->title);
printf("author: %s\n", book->author);
printf("price: %.2f\n", book->price);
printf("date: %u\n", book->date.year, book->date.month, book->date.day);
printf("publisher: %s\n", book->publisher);
}
int main(void)
{
int count = 1, zhiling, temp, i;
struct Book *b = NULL;
b = (struct Book *)malloc(sizeof(struct Book));
if(b == NULL)
{
printf("Failed!\n");
exit(1);
}
printf("Write the first book!\n");
getInput(&b);
do
{
printf("Enter an integer:(1 write a book/ 2 seek a book/ 0 leave): ");
scanf("%d", &zhiling);
switch(zhiling)
{
case 0:{
free(b);
printf("Thanks for use!\n");
return 0;
}break;
case 1:{
count++;
b = (struct Book *)realloc(b, count * sizeof(struct Book));
if(b == NULL)
{
printf("Failed!\n");
exit(1);
}
printf("This is No.%d book!\n", count);
getInput(&b);
}break;
case 2:{
for(i = 0; i < count; i++)
{
printf("No.%d book: %s\n", i + 1, b.title);
}
printf("Which one do you want?");
scanf("%d", &temp);
printBook(&b);
}break;
}
putchar('\n');
}while(1);
return 0;
}
