It is often hard to compare the value of two items if they are priced in different currencies. Write a program that will allow a user to enter the cost of a purchase in US dollars, Australian dollars, Euros, or UK pounds, and then convert the cost into any of the other currencies, as specified by the user. Use the following conversion factors in your program: A$ 1.00 = US $ 0.71 1.00 = US $ 1.12 UK 1.00 = US $1.42
