Down below is a menu-driven program about library operations. Help me because I don't know how to put an update and delete transactions. Also, please edit the program so it can have file manipulation/handling.
Required input:
CODE:
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
struct book
{
int b_no;
char b_name[40];
char b_author[40];
int no_pg;
};
int main()
{
struct book b[20];
int ch,n,i,count = 0;
char temp[40];
