Use An Ide Such As Visual Studio Or Eclipse For C To Produce This As

Use an IDE such as Visual Studio or Eclipse for C++ to produce this assignment. In this assignment, continue working on the project that you started in Week 1 according to the following details. You will design and implement at least 3 functions to allow customers to select products and quantities and to print the order summary (including the total price). Your program should provide the following additional functionality: ask customers to select multiple products and quantities, print the order summary, including the products, the quantities, and the total price for each product, and calculate and print the total price for the order. Compile and run the application to demonstrate a working program. Insert the screenshots into a Word document, add a short explanation on each, and save your Word document as “yourname_IP2.docx”.

Use An Ide Such As Visual Studio Or Eclipse For C To Produce This As

This paper presents the development of a simple customer order system in C++, designed to allow multiple product selections with corresponding quantities, and to generate an order summary including individual and total prices. The project utilizes an integrated development environment (IDE), specifically Visual Studio, to facilitate efficient coding, compiling, and testing processes. The code structure includes at least three core functions: one for displaying the product menu, one for processing customer selections, and one for printing the final order summary. These functions enable modularity, clarity, and reusability of code components, which are fundamental principles in software development.

Introduction

The purpose of this project is to create an interactive console application where customers can select multiple products, specify quantities, and receive a comprehensive order summary with pricing details. This task aligns with basic programming principles and introduces functions to improve code organization and maintainability. Utilizing Visual Studio, a widely used IDE for C++, streamlines the development workflow through features such as code editing, debugging, and project management.

Design and Implementation

The application is structured to facilitate user choices via a menu-driven interface. It begins with initializing product data, then prompts the customer to select products while specifying quantities. The three main functions are designed as follows:

  1. DisplayMenu(): Presents the list of products with prices.
  2. ProcessSelection(): Handles user input for selecting products and quantities, updating the order details accordingly.
  3. PrintOrderSummary(): Outputs a detailed order receipt including selected items, quantities, individual prices, total per item, and the grand total.

The code also uses an array or vector to store product data and order details, enabling flexible management of multiple items.

Sample Code

include <iostream>


include <vector>


include <iomanip>


using namespace std;


struct Product {


string name;


double price;


};


struct OrderItem {


Product product;


int quantity;


double totalPrice() const { return product.price * quantity; }


};


vector products = {


{"Apple", 0.99},


{"Banana", 0.59},


{"Orange", 1.29},


{"Grapes", 2.99},


{"Mango", 1.49}


};


vector orderItems;


void DisplayMenu() {


cout << "Product List:" << endl;


for (size_t i = 0; i < products.size(); ++i) {


cout << i + 1 << ". " << products[i].name << " - $" << fixed << setprecision(2) << products[i].price << endl;


}


}


void ProcessSelection() {


int choice;


char more;


do {


DisplayMenu();


cout << "Enter product number to select: ";


cin >> choice;


if (choice < 1 || choice > products.size()) {


cout << "Invalid choice. Try again." << endl;


continue;


}


int quantity;


cout << "Enter quantity: ";


cin >> quantity;


OrderItem item;


item.product = products[choice - 1];


item.quantity = quantity;


orderItems.push_back(item);


cout << "Would you like to add another product? (y/n): ";


cin >> more;


} while (more == 'y' || more == 'Y');


}


void PrintOrderSummary() {


double grandTotal = 0.0;


cout << "\nOrder Summary:" << endl;


cout << left << setw(15) << "Product" << right << setw(10) << "Qty" << setw(15) << "Price" << setw(15) << "Total" << endl;


for (const auto& item : orderItems) {


double totalPrice = item.totalPrice();


grandTotal += totalPrice;


cout << left << setw(15) << item.product.name << right << setw(10) << item.quantity << setw(15) << "$" << fixed << setprecision(2) << item.product.price << setw(15) << "$" << totalPrice << endl;


}


cout << "Grand Total: $" << fixed << setprecision(2) << grandTotal << endl;


}


int main() {


ProcessSelection();


PrintOrderSummary();


return 0;


}

This program effectively demonstrates functions for menu display, customer input processing, and order summary printing. It allows customers to select multiple products, specify quantities, and view a formatted receipt with total costs. The implementation showcases fundamental C++ programming constructs such as structs, vectors, loops, and I/O streams, aligned with best practices for modular code development in an IDE environment like Visual Studio.

Conclusion

Developing a simple customer order system in C++ using an IDE such as Visual Studio provides practical experience in modular programming and user interaction handling. The three core functions—displaying the menu, processing selections, and printing the order summary—structure the program logically, enabling easy modifications and enhancements. This project serves as a foundation for more complex systems involving databases, graphical interfaces, or web integration in future iterations.
