Answer to Question #188599 in C# for santhosh asrith

Question

The contract Employee class will have Perks as an additional property. The PermanentEmployee will have NoOfLeaves and ProvidendFund Properties.

1. Create these two classes by inheriting from the Employee class.

2. Override the GetSalary Method in these two classes. For Contract employee the new salary will be Salary + Perks. For Permanent Employee the new salary will be Salary – Providend Fund.

3. Create a console application to use these classes. Create a Menu driven application to select the Type of employee. Based on the user selection create the object and accept the details from the user. Also display the salary of the Employee.

4. As we only need to create instance of Contract Employee and Permanent Employee classes, Convert the Employee class to Abstract class. Also make GetSalary method Abstract in the Base class.
