Example: Menu with Single Item Selection in C++

// Menu with Single Item Selection
#include <iostream>
using namespace std;

int main() {
    int choice;
    int totalBill = 0;

    // Step 1: Display the menu
    cout << "Welcome to Our Hotel!" << endl;
    cout << "---------------------" << endl;
    cout << "Our Menu:" << endl;
    cout << "1. Coffee        - Rs. 50" << endl;
    cout << "2. Tea           - Rs. 40" << endl;
    cout << "3. Sandwich      - Rs. 120" << endl;
    cout << "4. Burger        - Rs. 180" << endl;
    cout << "5. Pizza         - Rs. 350" << endl;
    cout << "---------------------" << endl;

    // Step 2: Get user's choice
    cout << "Enter your choice: ";
    cin >> choice;

    // Step 3: Process the choice using a switch statement
    switch (choice) {
        case 1:
            cout << "You selected: Coffee. Rs. 50" << endl;
            totalBill += 50;
