Using structures, write the necessary declaration for information about books in a library.
Source Code
Brief explanation is provided after the source code.
#include <stdio.h>
typedef struct {
char *isbn[10];
char *title[255];
short int edition_number;
char *copyright[4];
} BOOK;
int main(int argc, char ** argv) {
BOOK book;
printf("ISBN: "); scanf("%s", book.isbn);
printf("\nTitle: "); scanf("%s", book.title);
printf("\nEdition Number: "); scanf("%d", &book.edition_number);
printf("\nCopyright: "); scanf("%s", book.copyright);
printf("\nISBN: "); printf("%s", book.isbn);
printf("\nTitle: "); printf("%s", book.title);
printf("\nEdition Number: "); printf("%d", book.edition_number);
printf("\nCopyright: "); printf("%s\n", book.copyright);
return 0;
}

Brief Explanation
- A structure in C is a collection of one or more variables, possibly of different types, grouped together under a single name for convenient handling.
- Using typedef, BOOK is created as a synonym for the structure. BOOK is then use in the main function to define a variable book of type structure. i.e BOOK book;
- scanf function reads data and assign to the fields define in the structure.
- Using printf function, the inputted data is displayed in a nice format to the stdout.
