Write a program that includes an Employee class in C# that can be used to calculate and print the take-home pay for a commissioned sales employee. All employees receive 7% of the total sales. Federal tax rate is 18%. Retirement contribution is 10%. Social Security tax rate is 6%. Write instance methods to calculate the commission income, federal and social security tax withholding amounts and the amount withheld for retirement. Use appropriate constants, design an object-oriented solution, and write constructors. Include at least one mutator and one accessor method; provide properties for the other instance variables. Create a second class to test your design. Allow the user to enter values for the name of the employee and the sales amount for the week in the second class.
