Question

Complete the following C# code that uses the DisplayPrice() method for displaying one price from the array of 4 prices. Because the DisplayPrice() method uses an array, an IndexOutOfRangeException might be thrown. Write a try block in which prompt the user for a subscript value and displays the appropriate price value stored in the corresponding array position. Create a catch block that catches any IndexOutOtRangeException, displays an appropriate error message and a price of $0.
