Today’s choices are 1.__________ 2._________ 3._______ 4.________

NOTE each _____ will say an item and its price for example pizza 2.99 Please choose 1 of the choices.

INVALID CHOICE and the cost will be $0.00 It will then say. Thank You and have a nice day!

Answer 1

Hey , because no language specified I am using JAVA langauge to code it.

--------------------------------------------------------------------------------

file-name:     Main.java
---------------------------------
import java.util.Scanner;

/*
 *  We continuously loop through the menu and ask user to enter his choice.
 * If user enters the valid choice, that porder price is added to totalPrice ( and it is declared as static )
 * And every time, customer places an order, it will show the current bill amount
 *
 * If the customer enters INVALID number, then we exit from the loop and show the total price
 *
 * If the user input is INVALID in the first iteration itself, then totalprice is shown as 0$.
 */
public class Main {
    static double totalPrice;

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);

        while(true) {
            System.out.println("Today's choices are: ");
            System.out.println("\t1. Pizza   3$ ");
            System.out.println("\t2. Veg Burger 5$");
            System.out.println("\t3. Biryani 70$ ");
            System.out.println("\t4. Chicken Soup 25$ ");

            System.out.println("--------------");
            System.out.print("Enter your choice: ");
            int choice = sc.nextInt();

            switch(choice) {
                case 1:
                    calculatePrice(3);
                    break;
                case 2:
                    calculatePrice(5);
                    break;
                case 3:
                    calculatePrice(70);
                    break;
                case 4:
                    calculatePrice(25);
                    break;
                default:
                    System.out.println("INVALID CHOICE");
                    System.out.println("Total price: "+totalPrice+"$");
                    System.out.println("THANK YOU! AND HAVE A NICE DAY ");
                    System.exit(0);
            }
        } // END of while

    } // END of main( ) method

    public static void calculatePrice(double Price) {
        totalPrice = totalPrice + Price;
        System.out.println("ordered successfully and current total is: "+totalPrice);
    }
} // END

OUTPUT:

If the user chooses INVALID option in the first iteration itself, then
