Hey @1Jawahir-Ali, here are the few basic steps to start. Hope this will assist you with your task.

1. Define the Structure of the Menu

   • Name of the dish

   • Price

   • Description (optional)

   • Category (e.g., starter, main course, dessert, drink)

     Sample code -

          struct MenuItem {
               string name;
               double price;
               string description;
               string category;};

2. Functions for Menu Operations

   • Add a menu item

   • Display all menu items

   • Display items by category

   • Search for a menu item

   • Calculate total price for orders

     Sample code -

      void addMenuItem(vector<MenuItem>& menu) {
              string name, description, category;
              double price;
              cout << "Enter the dish name: ";
              getline(cin, name);
              cout << "Enter the price: ";
              cin >> price;
              cin.ignore(); // to ignore the newline character
              cout << "Enter the description: ";
              getline(cin, description);
              cout << "Enter the category: ";
              getline(cin, category);
              menu.push_back(MenuItem(name, price, description, category));
             }
     

     note - Or you can use array or list based on preference

3. Menu Display
   You can create a function to display all menu items or filter by category.
   Sample code -

     void displayCategory(const vector<MenuItem>& menu, const string& category) {
          for (const auto& item : menu) {
               if (item.category == category) {
                   item.displayItem();
         }
      }
   }
   

4. Order System

   • Select multiple menu items
   • Calculate total cost

   Sample code -

   double calculateTotal(const vector<MenuItem>& menu, const vector<int>& order) {
          double total = 0.0;
                for (int index : order) {
                     total += menu[index].price;
                }
          return total;
      }

hello everyone hope that, all of you are well and enjoying your life.so I have completed the C++ area of procedural programming now I have been learning the new part of programming the "Object Oriented Programming" can you guide me in this regards how should I start OOP.

Seven Brew has a lot of drink choices, so having the brew menu 7 with prices available online actually saves time.

[kyiithelord]

Display food & drink menu

Show prices clearly

Categories (Starters, Main, Drinks, Desserts)

Take customer orders

Calculate total bill

🍴 I have simple ways to make your C++ Restaurant Menu System way better.

There is a specific way to make your programs more interactive by just using simple ways

1. Implement Logic-Based Sorting

As a developer, I may suggest that you to sort your food items in a ascending order by ids or names (recommended). First Sort your food items as per categories and then as per their names. use a std::vector of structs. This allows you to sort by name or price dynamically.
for eg:-

/----Beverages:--------------/
Chocolate Milkshake
Coke
Ice Tea
/----Burger-----------------/
Cheese Burger
Veg Burger

2 Add GST and Delivery Tax

Just Make a receipt section and add a float variable that takes input from user and gets added to total value.
For a realistic receipt, ensure your calculation logic handles floating-point precision carefully.

3 Use Colors For a Menu Driven Program (ANSI)

Just a usual formatter, Enhance user experience by adding colored text in your terminal-based program.

#define NORM  "\x1B[0m"
#define REDD  "\x1B[31m"
#define GREN  "\x1B[32m"
#define YELL  "\x1B[33m"
#define BLUE  "\x1B[34m"

Add a menu page where the customer can choose, add prices for each of the items, and add a source of income for the customers. You could do a ascii art style for the menu to make it good looking

[Cobb787]

Good morning! For a restaurant menu system in C++, focus on using classes for items (name, price, category) and vectors to store them. Start with basic CRUD operations: add, view, update, and delete items. You can also implement a search function and file handling to save data permanently.

For menu structure inspiration, I recently came across the dutch menu website, which has a clean and well-organized layout with pricing, it might give you some good ideas for how to display categories and items clearly in your project. Keep it simple first, then add features like tax calculation or order totaling later. Good luck with your project!

[unoursmarin]

C++ is an awesome langage to stay memory efficient, what you could do is a streming system using a camera that sends a stream (multiple images) to a s3 bucket and then a queuing system that analyses it :) (I basically did that on my public repo)

[aluoty]

Use struct and enum for your menu types, eg:

struct item {
    string name;
    unsigned long double price; //long is optional
    string type;
    string allergies;
    double duration; //for serving time, eg 01.10 mean 1 through 10 o'clock
    string specials; //discounts...
}

Also, try to add some UI, you can either use C++ libraries, or use a Web frontend like Typescript or Javascript with Astro or React or Vanilla for you and customers to have an easier insight.

[Cobb787]

For a restaurant menu system in C++, you could start by creating classes for menu items, categories, prices, and customer orders. A simple console-based interface would be a good starting point before adding more advanced features. It may also help to study real-world menu structures for inspiration. I came across this KFC menu website and was impressed by how the menu information is organized, which could give you some useful ideas for structuring your project.

[samuelklein1989]

Would it be better to create separate classes for menu items, categories, and orders, or use one main class with smaller supporting structures?

[samuelklein1989]

Hello everyone,

I am building a personal developer portfolio website and would appreciate advice from the community.

The website includes an introduction, technical skills, work experience, project cards, and a contact section. I want it to look professional and work consistently across desktop, tablet, and mobile devices.

I would appreciate suggestions about:

1. Organizing projects and case studies
2. Improving the responsive layout
3. Making navigation easier on mobile devices
4. Improving accessibility and keyboard support
5. Optimizing images and loading performance
6. Structuring the code for easier maintenance

Which improvements should I prioritize first? I would also appreciate recommendations about common portfolio mistakes that I should avoid.

Thank you for your guidance.

I suggest using a MenuItem class for the name, price, category, and availability, plus an Order class that stores selected items and calculates the total. Start with add, update, delete, search, and order functions, then add file storage so the menu remains available after the program closes.

[samuelklein1989]

A console-based version is a good starting point. I would also use separate MenuItem and Order classes, then add file storage so menu items and prices are saved between sessions.

[dtkachenko856-alt]

A good approach is to build the restaurant menu system in small stages. First, create a MenuItem class containing the item’s name, category, price, description, and availability. Then create an Order class that stores the selected menu items, changes quantities, removes items, and calculates the final bill.

Use a vector to hold the menu items and an enum for categories such as starters, main courses, desserts, and drinks. The first version can provide a simple console menu with these functions:

1. Display all menu items
2. Filter items by category
3. Search for an item by name
4. Add items to an order
5. Update quantities or remove items
6. Calculate the subtotal, tax, and final total
7. Print an order summary

After the basic system works, add file handling so menu information can be saved and loaded when the program restarts. You could use a text, CSV, or JSON file. Later, you can add administrator functions for creating, updating, and deleting menu items.

This structure is simple enough for a beginner but also provides a good way to practice C++ classes, objects, vectors, functions, file handling, and input validation.

[endbarggowpeev-arch]

One approach I’d consider is to design the program around the customer’s order flow, rather than treating the menu as just a list of records.

For example, each menu item could have an ID, while the ordering logic keeps track of the selected IDs and quantities. That makes it easier to handle cases such as ordering two of the same dish, removing an item, or changing its quantity.

You could split the project into a few responsibilities:

• A menu component responsible for loading and displaying available dishes.
• An order component responsible for selections and quantities.
• A billing function responsible for subtotal, tax, and the final amount.
• A separate input layer for validating things like item IDs and quantities.

I’d also keep the menu data separate from the user-interface code. That way, you can later replace the console interface without having to rewrite the underlying ordering logic. Once that structure is working, persistence and admin features can be added without making the main program difficult to maintain.
