Question

In Chapter 7, you modified the GreenvilleRevenue program to include a number of methods.

Now, using your code from Chapter 7 Case Study 1, modify your program so every data entry statement uses a TryParse() method to ensure that each piece of data is the correct type.

Any invalid user entries should generate an appropriate message that contains the word Invalid, and the user should be required to reenter the data.

An example of the program is shown below:

Enter number of contestants

0
Other
Enter talent code >> Sarah.
Invalid format - entry must be a single character
That is not a valid code
Enter talent code >> R
That is not a valid code
Enter talent code >> J
That is not a valid code
Enter talent code >> S
Enter contestant name >> Sarah
Talent codes are:
S
