Continue with Assignment “Loan Program”. Read code “SquareRootTest”.

1. class Program
    {

        public static double loanAmount;
        public static double years;
        public static double interest;
        static void Main(string[] args)
        {

         …..
         //for loanAmount
         do {
       
         }while ( continueLoop );

         …..
         //for years
         do {
       
         }while ( continueLoop );

         …..
         //for interest
         do {
       
         }while ( continueLoop );

        }
        …..
    }

2. Create a class “MyRangeException.cs”.

3. Add Exception Handling
   – loanAmount
      – must be a number, threw FormatException if not
      – must be greater than 50000, throw Exception if not
             – Create a method CheckLoanAmount(double la)
               throw new MyRangeException(“Loan Amount must be $50,000 or more.”);
    

   – loanInterest
      – must be a number, threw FormatException if not
      – must be greater than 1%, throw Exception if not
             – Create a method CheckLoanInterest(double it)
               throw new MyRangeException(“Interest Rate must be 1% or more.”);

    – years
      – must be a number, threw FormatException if not
      – must be greater than 5, throgh Exception if not
             – Create a method CheckLoanYears(double yr)
               throw new MyRangeException(“Years must be 5 years or more.”);
