Question

***IN JAVA***

5. Currency conversion: Write a snippet that first asks the user to type

  today's US dollar price for one  Euro. Then use a loop to:

-- prompt the user to enter a Euro amount. (allow decimals)

-- convert that amount to US dollars. (allow decimals)

-- print the amount to the screen, formatted to two decimal places

Use 0 as a sentinel to stop the loop.

Answer 1

// EurosToUS.java
import java.util.Scanner;
public class EurosToUS {
    public static void main(String[] args) {
        // Create a Scanner object to read input.
        Scanner scan = new Scanner(System.in);

        System.out.print("Enter today's US dollar price for one  Euro: ");
        double dollarPrice = scan.nextDouble();

        System.out.print("Enter a Euro amount: ");
        double euros = scan.nextDouble();

        while(euros!=0){
            System.out.println(dollarPrice*euros+" dollars");
            System.out.print("Enter a Euro amount: ");
            euros = scan.nextDouble();
        }
    }
