The Program should display the menu at the start (with 10 dishes).

Question

You are required to create an MVP (Minimal Viable Product) to take customer orders for a local ethnic food restaurant in Kathmandu. The restaurant offers 10 different types of food dishes, taken from the local ethnic food culture. The restaurant operates with limited dishes and limited staff. You are required to create a prototype of order taking system to ease the working process within the restaurant. Your program should have the following functionalities:

The Program should display the menu at the start (with 10 dishes). These dishes should be stored in a text file as shown below. Your program should load these dishes by reading this file:

MoMo Steam – 150

MoMo Fried - 170

Chowmein – 175

Bhutan – 195

Chhoila – 205

Cold Drinks – 75

Khaja Set – 195

Bara Set – 115

Fried Rice – 125

Omelette - 45

2. Each customer will make an order based on the menu shown. For each order, the system should calculate the total bill. For each bill, after adding the sum total of the prices of the dishes, the sum total would be subject to 10% service Tax and 13% VAT.

3. For every new instance where a customer (new or repeating) makes an order, a new bill is generated.

4. Altering a confirmed order would not be a necessary feature for the MVP phase of the system.

5. Your program should save the total order amount and total order count for each day in a separate file.

6. Implement Function Overloading while building your solution. Your program should make suitable implementation of classes, objects and other required features of C++ including file handling mechanism.

Answer 1

You should approach this by building a simple C++ menu-based ordering system using classes and file handling.

First, store the 10 menu items in a text file and read them into arrays or a vector when the program starts, then display the menu to the customer.Create a class like Order that handles adding items, calculating subtotal, and generating the final bill. After the customer selects items, calculate total price, then apply 10% service tax and 13% VAT on the subtotal to get the final bill.Each time a customer places an order, treat it as a new object and generate a fresh bill. You don’t need to support editing orders for this MVP.Use function overloading for things like calculating totals (for example, one function for item list, another for direct amount calculation).Finally, store daily summary data in a file, including total number of orders and total revenue for the day, updating it each time a bill is generated.This keeps the system simple, modular, and aligned with MVP requirements.
