Accessing structure members in C++ - Mini Project: Build & Apply

Accessing structure members

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

🎯 Goal: Build a program that defines a structure for a book, stores information in it, and prints the book's details by accessing its members.

📋 What You'll Learn

Define a structure named Book with members title, author, and year.

Create a variable of type Book and assign values to its members.

Access and print the members of the Book variable.

💡 Why This Matters

🌍 Real World

Structures help organize related data together, like storing details about books, students, or products in real applications.

💼 Career

Understanding how to define and access structures is fundamental for many programming jobs, especially in systems programming, game development, and software engineering.

1

Define the Book structure

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

C++

#include 
#include 

// Define the Book structure here

int main() {

    return 0;
}

Need a hint?

Use the struct keyword to define Book with the specified members.

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

    return 0;
}

Need a hint?

Create a variable of type Book and use the dot . operator to assign values to its members.

3

Access and print the Book members

Use std::cout to print the book details in this exact format:
Title: The Great Gatsby
Author: F. Scott Fitzgerald
Year: 1925
Access the members of myBook using the dot operator.

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 book details here

    return 0;
}

Need a hint?

Use std::cout and the dot operator to print each member on its own line.

4

Run the program to display the book details

Run the program and ensure it prints exactly:
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 << std::endl;
    std::cout << "Author: " << myBook.author << std::endl;
    std::cout << "Year: " << myBook.year << std::endl;

    // Run the program to see output
}

Make sure your output matches exactly, including capitalization and spacing.
