We'll perform operations on individual members of the structure, such as displaying book details and updating the number of pages.

Examples :

Program.c

#include <stdio.h> // Define a structure named Book struct Book { char title[100]; char author[50]; int year; int pages; }; // Function to display book details void displayBook(struct Book book) { printf("\nBook Details:\n"); printf("Title: %s\n", book.title); printf("Author: %s\n", book.author); printf("Year: %d\n", book.year); printf("Pages: %d\n", book.pages); } int main() { // Declare a variable of type Book struct Book myBook; // Input for book details printf("Enter book title: "); scanf("%s", myBook.title); printf("Enter author name: "); scanf("%s", myBook.author); printf("Enter publication year: "); scanf("%d", &myBook.year); printf("Enter number of pages: "); scanf("%d", &myBook.pages); // Display book details displayBook(myBook); // Update the number of pages printf("\nEnter updated number of pages: "); scanf("%d", &myBook.pages); // Display updated book details displayBook(myBook); return 0; }

• Structure Definition: Define a structure named Book with members title (string), author (string), year (integer), and pages (integer).
• Function Definition: Create a function displayBook that takes a Book as a parameter and displays its details.
• Variable Declaration: Declare a variable of type Book named myBook.
• Input: Get input from the user for the book details.
• Display Book Details: Print the details of the entered book using the displayBook function.
• Update Information: Allow the user to update the number of pages for the book.
• Display Updated Book Details: Print the updated details using the displayBook function.
• Compilation and Execution: Compile and run the program. Enter the book details and the updated number of pages as prompted.
