Class definition syntax in C++ - Mini Project: Build & Apply

Class definition syntax

📖 Scenario: You are creating a simple program to represent a book in a library system.

🎯 Goal: Build a C++ class called Book with basic information and display it.

📋 What You'll Learn

Create a class named Book

Add two public member variables: title and author of type std::string

Create an object of class Book with specific values

Print the book's title and author

💡 Why This Matters

🌍 Real World

Classes like <code>Book</code> help organize data in programs such as library management systems or book stores.

💼 Career

Understanding class syntax is essential for software development jobs that use C++ for building applications with structured data.

1

Create the Book class with public member variables

Write a class definition named Book with two public std::string variables: title and author.

C++

#include 
#include 

// Define class Book with public variables title and author
// Your code here

Need a hint?

Use class Book { public: std::string title; std::string author; };

2

Create a Book object with specific values

Create a Book object named myBook. Set myBook.title to "The Great Gatsby" and myBook.author to "F. Scott Fitzgerald".

C++

#include 
#include 

class Book {
public:
    std::string title;
    std::string author;
};

// Create Book object myBook and set title and author
// Your code here

Need a hint?

Use Book myBook; then assign values with myBook.title = "The Great Gatsby"; and myBook.author = "F. Scott Fitzgerald";

3

Add code to print the book's title and author

Inside main(), add std::cout statements to print myBook.title and myBook.author on separate lines.

C++

#include 
#include 

class Book {
public:
    std::string title;
    std::string author;
};

int main() {
    Book myBook;
    myBook.title = "The Great Gatsby";
    myBook.author = "F. Scott Fitzgerald";
    // Print title and author
    // Your code here
    return 0;
}

Need a hint?

Use std::cout << myBook.title << std::endl; and similarly for author.

4

Run the program to display the book details

Run the program. It should print the title The Great Gatsby on the first line and the author F. Scott Fitzgerald on the second line.

C++

#include 
#include 

class Book {
public:
    std::string title;
    std::string author;
};

int main() {
    Book myBook;
    myBook.title = "The Great Gatsby";
    myBook.author = "F. Scott Fitzgerald";
    std::cout << myBook.title << std::endl;
    std::cout << myBook.author << std::endl;
    // Run the program to see output
    // Your code here
    return 0;
}

Need a hint?

Make sure you run the program and check the output matches exactly.
