Create the definition for a loan object. The object will contain methods to "set" and "get" the loan amount. a yearly interest rate, number of years and the number of payments per year. It will also contain a method that returns the payment amount (Note payments per year is "normally" 12 and in that case the payment amount would indicate the monthly payment). Include if statements in the object, so that "bad" values can not get into the object.

Write a C# program to create and test a loan object. Add if statements to your program to prevent bad values being sent to a loan object. Please include all code.
