Simple C++ program for a basic tally system

 Here's a simple C++ program for a basic tally system:

#include <iostream>

#include <string>

using namespace std;

class Tally {

private:

    string itemName;

    int quantity;

    double price;

public:

    Tally(string itemName, int quantity, double price) {

        this->itemName = itemName;

        this->quantity = quantity;

        this->price = price;

    }

    void display() {

        cout << "Item Name: " << itemName << endl;

        cout << "Quantity: " << quantity << endl;

        cout << "Price: " << price << endl;

        cout << "Total: " << quantity * price << endl;

    }

};

int main() {

    int choice;

    string itemName;

    int quantity;

    double price;

    do {

        cout << "Tally System" << endl;

        cout << "1. Add Item" << endl;

        cout << "2. Display Item" << endl;

        cout << "3. Exit" << endl;

        cout << "Enter your choice: ";

        cin >> choice;

        switch (choice) {

            case 1:

                cout << "Enter item name: ";

                cin.ignore();

                getline(cin, itemName);

                cout << "Enter quantity: ";

                cin >> quantity;

                cout << "Enter price: ";

                cin >> price;

                Tally item(itemName, quantity, price);

                item.display();

                break;

            case 2:

                // Add code to display all items

                break;

            case 3:

                cout << "Exiting program..." << endl;

                break;

            default:

                cout << "Invalid choice. Please try again." << endl;

        }

    } while (choice != 3);

    return 0;

}

This program creates a simple tally system with the following features:

- Adds items with name, quantity, and price

- Displays the item details along with the total price

- Allows users to exit the program

Note that this is a basic implementation and can be extended to include more features 

like storing items in a database, calculating totals, and generating reports.
