• Exercise 11 on page 86, but with the following modifications: instead of using U.S. currency, write your program for the Euro. Note that Euro coins come in different denominations from U.S. coins; there are 8 that you must account for. Report to the user the individual counts (as in the original problem) and the sum in Euros and cents (instead of dollars and cents). In addition, convert the final value to U.S. dollars using a recent exchange rate (do not worry about rounding the result, for now).
