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 last year >> 1 Enter number of contestants this year >> 2 Last year's competition had 1 contestants, and this year's has 2 contestants Revenue expected this year is $50.00 The competition is bigger than ever! Enter contestant name >> Matt Talent codes are: S Singing D Dancing M Musical instrument O 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 Singing D Dancing M Musical instrument O Other Enter talent code >> D The types of talent are: Singing 1 Dancing 1 Musical instrument 0 Other 0 Enter a talent type or Z to q
