ArrayConvertingCurrency

Beginning C++ student needing help with code and logic on this one. Any skilled C++ programmer that has 20 minutes to devote to this one?

... the problem is to allow user to select a currency to convert from, then select a currency to convert to. Ask user how many monetary units to convert and display all the user-selected info as well as display the conversion figures... the logic has me stumped.
