In this exercise, you create a program that converts US Dollars to a different currency. The currencies and exchange rates are listed in Figure 6-47. The user should be allowed to choose the currency. (Hint: Designate a code for each currency and use cout statements to display the code and corresponding currency.) The number of American Dollars should always be an integer that is greater than or equal to zero.

a. Create an IPO chart for the problem, and then desk-check the algorithm nine times. For the first seven desk-checks, convert 10 American Dollars to each of the seven different currencies. For the eighth desk-check, test the algorithm using -3 as the number of American Dollars. For the last deck-check, test the algorithm using an invalid currency code.

b. List the input, processing, and output items, as well as the algorithm, in a chart similar to the one shown earlier in Figure 6-42. Then code the algorithm into a program.

c. Desk-check the program using the same data used to desk-check the algorithm.

d. Enter your C++ instructions into a source file named Advancedl7.cpp. Also enter appropriate comments and any additional instructions required by the compiler. Display the results in fixed-point notation with two decimal places.

e. Save and run the program. Test the program using the same data used to desk-check the program.
