Book Arrows

This program has some ambiguitiy in the setter functions and suboptimal readability in the main function. Improve the ambiguity and readability of this code by adding arrow operators.

#include <iostream>
#include <string>

struct Book {
private:
    std::string title;
    std::string author;
public:
    // setter and getter functions for author
    void set_title(const std::string& title) {
        title = title;
    }
    std::string get_title() const {
        return title;
    }

    // setter and getter functions for author
    void set_author(const std::string& author) {
        author = author;
    }
    std::string get_author() const {
        return author;
    }

    // Method to print book details
    void printDetails() {
        std::cout << "Title: " << title << ", Author: " << author << std::endl;
    }
};

int main() {
    // Creating a Book object dynamically
    Book* myBook = new Book();

    (*myBook).set_title("The Great Gatsby");
    (*myBook).set_author("F. Scott Fitzgerald");

    (*myBook).printDetails();

    // Deleting the Book object to free memory
    delete myBook;

    return 0;
}

Hint

(*myBook). can be changed to myBook->.

Use this-> inside get_author and get_title.

Answer

#include <iostream>
#include <string>

struct Book {
private:
    std::string title;
    std::string author;

public:
    // setter and getter functions for author
    void set_title(const std::string& title) {
        this->title = title;
    }
    std::string get_title() const {
        return title;
    }

    // setter and getter functions for author
    void set_author(const std::string& author) {
        this->author = author;
    }
    std::string get_author() const {
        return author;
    }

    // Method to print book details
    void printDetails() {
        std::cout << "Title: " << title << ", Author: " << author << std::endl;
    }
};

int main() {
    // Creating a Book object dynamically
    Book* myBook = new Book();

    // Setting the title and author with arrow operators
    myBook->set_title("The Great Gatsby");
    myBook->set_author("F. Scott Fitzgerald");

    myBook->printDetails();

    // Deleting the Book object to free memory
    delete myBook;

    return 0;
}

It's worth noting that the changes to set_author and set_title could be resolved by renaming the parameter.
