Answer to Question #253030 in C# for Israel

Question

Write a program that calculates the take home pay of an employee. The two employees are salaried and hourly. Allow the user to input employee type. If an employee is salaried, allow the user to input the salary amount. If an employee is hourly, allow the user to input the hourly rate and the number of hours clocked for the week. For hourly employees, overtime is paid for hours over 40 at a rate of 1.5 of the base rate. For all employees’ take-home pay federal tax of 18% is deducted. A retirement contribution of 10% and a social security tax rate of 6% should be deducted. Use appropriate constants. Design an object oriented solution.
