Book Array

cin.ignore() skips (ignores) the next character in the input buffer. In this case we're ignoring the newline character ('\n') left in the buffer after reading input with std::cin. This ensures that subsequent calls to std::getline work correctly without immediately capturing the leftover newline character.

• Add "display_info" function to the Book struct that prints the title, author, and page_count of the book

• Add "display_info" function to the Book struct that prints the title, author, and page_count of the book

Define a Book struct that includes the member variables: title, author, and page_count. Create an array of 3 Book objects, set their member variables, and print the details of each book in the array using a loop.

You can initialize the array with specific values directly or use std::cin to input the values.

Hint

Use std::getline to properly read the title and author strings with spaces if you're using std::cin to input the values.

Answer

#include <iostream>
#include <string>

struct Book {
    std::string title;
    std::string author;
    int page_count;
};

int main() {
    Book books[3];

    for (int i = 0; i < 3; ++i) {
        std::cout << "Enter the title of book " << i+1 << ": ";
        std::cin.ignore();
        std::getline(std::cin, books[i].title);

        std::cout << "Enter the author of book " << i+1 << ": ";
        std::getline(std::cin, books[i].author);

        std::cout << "Enter the page count of book " << i+1 << ": ";
        std::cin >> books[i].page_count;
    }

    std::cout << "\nBook Details:\n";
    for (int i = 0; i < 3; ++i) {
        std::cout << "Book " << i+1 << ":\n";
        std::cout << "Title: " << books[i].title << std::endl;
        std::cout << "Author: " << books[i].author << std::endl;
        std::cout << "Page Count: " << books[i].page_count << std::endl;
        std::cout << std::endl;
    }

    return 0;
}
