arraymenuitems.cpp

In the following snippet, I want the menu variable to have empty content at index 0, the current contents of index 0 to be at index1, and the current contents
of index 1 at index2 


#include <iostream>
#include <vector>
#include <string>

// Define a struct to represent menu items
struct MenuItem {
    std::string name;
    std::vector<std::string> options;
};

int main() {
    // Initialize menu items directly in an array
    std::vector<MenuItem> menu = {
	    {"", {}}, // or std::optional<std::string> name; and  {std::nullopt, {}},  
        {"Victoria", {"Melbourne", "Geelong", "Ballarat", "Bendigo"}},
        {"New South Wales", {"Sydney", "Newcastle", "Wollongong", "Albury"}}
    };

    // Example usage
    for (const auto& item : menu) {
        std::cout << "Menu for " << item.name << ":\n";
        for (const auto& option : item.options) {
            std::cout << "- " << option << "\n";
        }
        std::cout << "\n";
    }

    return 0;
}


    // Example usage using range-based for loop and structured bindings
    for (const auto& [name, options] : menu) {
        if (name) {
            std::cout << "Menu for " << *name << ":\n";
        } else {
            std::cout << "Empty menu item:\n";
        }
        for (const auto& option : options) {
            std::cout << "- " << option << "\n";
        }
        std::cout << "\n";
    }


I have this code

struct MenuItem {
    std::string name;
    std::vector<std::string> options;
};

int main() {
    // Initialize menu items directly in an array
    std::vector<MenuItem> menu = {
	    {"", {}}, // or std::optional<std::string> name; and  {std::nullopt, {}},  
        {"Victoria", {"Melbourne", "Geelong", "Ballarat", "Bendigo"}},
        {"New South Wales", {"Sydney", "Newcastle", "Wollongong", "Albury"}}
    };

    // Example usage
    for (const auto& item : menu) {
        std::cout << "Menu for " << item.name << ":\n";
        for (const auto& option : item.options) {
            std::cout << "- " << option << "\n";
        }
        std::cout << "\n";
    }

    return 0;
}

I want to create a class called TFTMenu. It needs a class member called menu and it needs to be initialized with the menu variable in the previous
code snipper


#include <iostream>
#include <string>
#include <vector>

struct MenuItem {
    std::string name;
    std::vector<std::string> options;
};

class TFTMenu {
public:
    TFTMenu() = default; // Default constructor

    // Method to set the menu and take ownership using std::move
    void set_menu(std::vector<MenuItem>&& menu) {
        menu_ = std::move(menu);
    }

    void displayMenu() const {
        for (const auto& item : menu_) {
            std::cout << "Menu for " << item.name << ":\n";
            for (const auto& option : item.options) {
                std::cout << "- " << option << "\n";
            }
            std::cout << "\n";
        }
    }

private:
    std::vector<MenuItem> menu_;
};

int main() {
    std::vector<MenuItem> menu = {
        {"", {}}, // or std::optional<std::string> name; and  {std::nullopt, {}},  
        {"Victoria", {"Melbourne", "Geelong", "Ballarat", "Bendigo"}},
        {"New South Wales", {"Sydney", "Newcastle", "Wollongong", "Albury"}}
    };

    TFTMenu tftMenu;
    tftMenu.set_menu(std::move(menu)); // Set the menu

    tftMenu.displayMenu();

    return 0;
}
