IN C#

In previous chapters, you created applications for the Greenville Idol competition.

Now, modify the version of the GreenvilleRevenueprogram created in Chapter 5 so that after the user enters the number of contestants in this years competition, the user is prompted for the appropriate number of contestant names and a code for each contestant that indicates the type of talent:

S for singing

D for dancing

M for playing a musical instrument

O for other.

Make sure that all entered codes are valid, and if not, reprompt the user to enter a correct code. For example, if Y is input, output Y is not a valid code, and reprompt the user until a valid code is entered.

After contestant data entry is complete, display a count of each type of talent. For example, if there were ten singers, four dancers, 7 people who play musical instruments, and 1 in the other category, the output should be:

The types of talent are: Singing 10 Dancing 4 Musical instrument 7 Other 1 

Then, continuously prompt the user for a talent code until the user enters a sentinel value (the uppercase character Zshould be used as the sentinel value).

With each code entry, display a list of the contestants with that code, or display a message that the code is not valid and reprompt the user. For example, if M is entered, the output might be:

Contestants with talent Musical instrument are: Michelle Nick 

If U is entered, the output should be U is not a valid code.

Code to reuse is below:
