Question

//Question 1: Currency conversion
// Write some code that first asks the user to type the current
// conversion rate for 1 U.S. Dollar (USD) to 1 Euro. Next, in a while
// loop, ask users for an amount in USD, read it in, and convert it to
// Euro, printing as you go. Use 0 as a sentinel (i.e.: a signal to
// stop the loop).
// Here's a sample run:
// Whats the current conversion rate for 1 USD to 1 Euro:
// .85
// Enter an amount in USD:
// 10.0
// 10.0 in USD is equal to 8.5 Euro
// Enter an amount in USD:
// 2.0
// 2.0 in USD is equal to 1.7 Euro
// Enter an amount in USD:
// 0
// Quitting...
