Canteen Management System in C++
Creating a full-fledged Canteen Management System in C++ is a complex project beyond the scope of a single response. However, I can provide you with a simplified example that demonstrates some basic functionality you might find in such a system. This simplified system will include features like adding food items, placing orders, and calculating the total bill. In a real-world scenario, you would likely need a database to manage the data.
Here’s a basic outline of a Canteen Management System in C++:
#include <iostream>
#include <vector>
#include <string>
// Structure to represent a food item
struct FoodItem {
std::string name;
double price;
};
// Function to display the menu
void displayMenu(const std::vector<FoodItem>& menu) {
std::cout << "Menu:" << std::endl;
for (const FoodItem& item : menu) {
std::cout << item.name << " - $" << item.price << std::endl;
}
}
// Function to place an order
void placeOrder(std::vector<FoodItem>& menu) {
int choice;
std::cout << "Enter the item number to order (1-" << menu.size() << "): ";
std::cin >> choice;
if (choice >= 1 && choice <= menu.size()) {
const FoodItem& selected = menu[choice - 1];
std::cout << "You ordered: " << selected.name << " - $" << selected.price << std::endl;
} else {
std::cout << "Invalid choice." << std::endl;
}
}
int main() {
std::vector<FoodItem> menu;
menu.push_back({"Burger", 4.99});
menu.push_back({"Pizza", 6.99});
menu.push_back({"Fries", 2.49});
menu.push_back({"Soda", 1.49});
int option;
do {
std::cout << "\nCanteen Management System" << std::endl;
std::cout << "1. Display Menu" << std::endl;
std::cout << "2. Place Order" << std::endl;
std::cout << "3. Exit" << std::endl;
std::cout << "Enter your choice: ";
std::cin >> option;
switch (option) {
case 1:
displayMenu(menu);
break;
case 2:
placeOrder(menu);
break;
case 3:
std::cout << "Exiting the program." << std::endl;
break;
default:
std::cout << "Invalid choice. Please try again." << std::endl;
}
} while (option != 3);
return 0;
}In this simplified example:
- The
FoodItemstruct represents a food item with a name and price. - The
displayMenufunction displays the menu, and theplaceOrderfunction allows the user to place an order. - The
mainfunction includes a menu-driven interface that lets users view the menu, place orders, and exit the program.
Please note that this is a basic demonstration, and a real-world Canteen Management System would involve additional features like user authentication, managing orders, tracking inventory, and processing payments. You would also need a database or a file system to store and retrieve data persistently.
