Sample code: The comments (// ...) give you hints about the code you need to add to make the program work.

Write a program in C# that calculates compound interest The formula for compound interest is: A P+(r/m) Where A = Accrued Amount (principal plus interest) P-Principal Amount r Annual interest rate (as decimal) t = Number of years Number of times interest is compounded per year Write the program using methods. Finish the method heading of two methods - WelcomeMessage0 and ExitProgram0 - by selecting the appropriate moditfiers and return types, and finish the header and method body of OutputResult0. Finally, implement two CalculateCompoundInterest0 methods which calculate the accrued amount - one which takes as parameters the principal, interest rate, and number of years accumulating interest, and assumes the number of times interest is compounded per year is daily (365), and another that allows the number of compounds per year to be specified Your code will be run by calling the two versions of the CalculateCompoundInterest0 method, OutputResult0 and ExitProgram0 methods directly. As a result, make sure you make these methods public
