Interactive Input and Output, File Input, Expressions, and Defined Constants

Description You live in the Czech Republic, where the currency is the koruna. The koruna, like most currencies, is valued against the dollar differently over time. You find that on January 1 in one particular year that 42 korunas are worth one U.S. dollar. A year later you discover that one U.S. dollar is now worth 37 korunas. Write an interactive program that prompts the user for how many korunas the user has in a savings account, and calculates the difference in the number of U.S. dollars between the first year's rate and the second year's rate. In this assignment, you develop a program to convert currency from korunas to dollars at two different exchange rates. This program is to be written so that input is interactive (obtained from the user), and some of the output (the "report") is printed directly to a disk file (see specs below for naming convention).
