Defining structures in C++ - Mini Project: Build & Apply

Defining structures

📖 Scenario: You are creating a simple program to store information about a book in a library system.

🎯 Goal: Build a program that defines a Book structure, sets up a book's details, and prints them.

📋 What You'll Learn

Define a structure named Book with three members: title (string), author (string), and year (integer).

Create a variable of type Book named myBook.

Assign the title "The Great Gatsby", author "F. Scott Fitzgerald", and year 1925 to myBook.

Print the book details in the format: Title: The Great Gatsby, Author: F. Scott Fitzgerald, Year: 1925.

💡 Why This Matters

🌍 Real World

Structures are used to group related information, like details about a book, a person, or a product, making data easier to manage.

💼 Career

Understanding structures is important for jobs involving C++ programming, embedded systems, game development, and any software that needs organized data.

1

Define the Book structure

Define a structure called Book with three members: title and author of type std::string, and year of type int.

C++

#include 
#include 

// Define the Book structure here

int main() {

    return 0;
}

Need a hint?

Use the struct keyword followed by the structure name Book. Inside curly braces, declare the members with their types.

2

Create a Book variable and assign values

Inside main(), create a variable named myBook of type Book. Assign "The Great Gatsby" to myBook.title, "F. Scott Fitzgerald" to myBook.author, and 1925 to myBook.year.

C++

#include 
#include 

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

int main() {
    // Create myBook and assign values here

    return 0;
}

Need a hint?

Declare myBook as Book myBook;. Use dot notation to assign values to each member.

3

Print the book details

Use std::cout to print the book details in this exact format: Title: The Great Gatsby, Author: F. Scott Fitzgerald, Year: 1925.

C++

#include 
#include 

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

int main() {
    Book myBook;
    myBook.title = "The Great Gatsby";
    myBook.author = "F. Scott Fitzgerald";
    myBook.year = 1925;

    // Print the book details here

    return 0;
}

Need a hint?

Use std::cout with the insertion operator << to print each part with commas and spaces exactly as shown.

4

Run and display the output

Run the program and print the output showing the book details exactly as: Title: The Great Gatsby, Author: F. Scott Fitzgerald, Year: 1925.

C++

#include 
#include 

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

int main() {
    Book myBook;
    myBook.title = "The Great Gatsby";
    myBook.author = "F. Scott Fitzgerald";
    myBook.year = 1925;

    std::cout << "Title: " << myBook.title << ", Author: " << myBook.author << ", Year: " << myBook.year << std::endl;

    // Program output
}

Need a hint?

Make sure the output matches exactly, including commas and spaces.
