question:

Develop a program to allow users to perform operations on book records.
A book record should contain the below minimum information:

· ISBN : 10 characters
· Title : 30 characters
· Author : 30 characters
· Price : floating point number
· Category : an enumerated type of SF-Science Fiction, HR-Horror, RM-Romance
· PublishedDate : date format in nested date structure type dd/mm/yyyy

You program should be able to store up to 10 book records in an array called BookArray

Your program should at least perform the below operations:

· Add book records in BookArray
· Display all book records
· Find and display book information given the ISBN

· Find all books written by a particular Author
· Delete book record given the Title

this is the program!




#include <stdio.h>
#include <string.h>

{
SF_Science_Fiction=0, HR_Horror=1, RM_Romance=2
