Microsoft Visual C# 7th edition. 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.
Cengage requirement for the shaded part is attached andI don't understand it. I need help
with the highlighted part (getContestantData() method) please. Thanks
Overview:A new bank wants to make a simple application to keep track of all accounts and transactions. In this TMA, it is required to help the bank manager implement the required application.Requirements:After a quick meeting with the bank manager, you got the following information: It is required to store all bank accounts in one collection and all the transactions happened in another collection. Each account has a unique account number, a holder and balance. There is a specific prefix (common for all accounts) that should be added to the holder's civil id to create the unique account number. In addition, it is not allowed for a holder to have more than one account. Furthermore, only three transactions are allowed on any account: deposit, withdrawal and transfer money to another account. Each holder has a unique civil ID (national id), a name and other attributes (add at least 2 attributes from your choice). For each transaction, it is required to store the account(s) affected,…
