C++ Menu Code Example: Simple & Efficient

Here is an example of a menu in C++:

#include <iostream>
using namespace std;

int main() {
    int choice;
    do {
        cout << 'Menu:' << endl;
        cout << '1. Option 1' << endl;
        cout << '2. Option 2' << endl;
        cout << '3. Option 3' << endl;
        cout << '4. Exit' << endl;
        cout << 'Enter your choice: ';
        cin >> choice;
        switch (choice) {
            case 1:
                // code for option 1
                break;
            case 2:
                // code for option 2
                break;
            case 3:
                // code for option 3
                break;
            case 4:
                cout << 'Goodbye!' << endl;
                break;
            default:
                cout << 'Invalid choice. Please try again.' << endl;
                break;
        }
    } while (choice != 4);
    return 0;
}

This menu displays four options and allows the user to enter their choice. If the user enters an invalid choice, the program displays an error message and prompts them to try again. The program continues to display the menu until the user chooses to exit.
