Enumerated types are useful, but safety is not always guaranteed. To illustrate, the following code would compile: Color c = 10; even though there is no color corresponding to the integer 10. What happens if you call your getCost function using such a color? To prevent this, we will add additional code to detect and handle this type of error situation. 1. Add another enumerated type called Error that will recognize the following error types: No Error, Unavailable Selection Error, Invalid Argument Error, and Null Pointer Error (note: a good convention is to use all-caps with words separated by an underscore). 2. Add additional code and checks to your getCost function to check for valid input (on all the arguments). 3. Modify the getCost method to return one of your enumerated types based on the type of error encountered. 4. Modify your main program to check for the type of error returned and print an appropriate error message.
