Question

Create a C structure which stores information about a book. Each book should have the following data: Author (string), Title (string), Publisher (string), Year (int), ISBN (int), Genre (string), Price (float). Write a C program which creates an array of 100 of these structures, then prompts the user to enter book information to fill the array. The data entry should stop when the array is full, or when the user enters 0 for the ISBN.

Answer:

Code:

#include <stdio.h>
struct Book {
    char author[20];
    char title[40];
    char publisher[20];
    int year;
    int isbn;
    char genre[5];
    float price;
};
int main(){
    struct Book books[100];
    int count = 0;
    do {
        int isbn;
        printf("\nEnter ISBN (or 0 to stop): ");
        scanf("%d", &isbn);
        if (isbn == 0)
            break;
        books[count].isbn = isbn;
        fflush(stdin);
        printf("Enter author: ");
        scanf("%[^\n]%*c", &books[count].author);
        printf("Enter title: ");
        scanf("%[^\n]%*c", &books[count].title);
        printf("Enter publisher: ");
        scanf("%[^\n]%*c", &books[count].publisher);
        printf("Enter year: ");
        scanf("%d", &books[count].year);
        fflush(stdin);
        printf("Enter genre: ");
        scanf("%[^\n]%*c", &books[count].genre);
        printf("Enter price: ");
        scanf("%f", &books[count].price);
        count += 1;
    }
    while(1);
    // remove lines C1 and C2 to print entered book details
    /*************************************** C1 ************************************************
    for(int i = 0; i < count; i++){
        printf("\nBook %d\nISBN: %d\nAuthor: %s", i+1, books[i].isbn, books[i].author);
        printf("\nTitle: %s\nPublisher: %s", books[i].title, books[i].publisher);
        printf("\nGenre: %s\nYear: %d\nPrice: %f\n", books[i].genre, books[i].year, books[i].price);
    }
    *************************************** C2 ************************************************/
    return 0;
}
