Answer to Question #240039 in C# for Gayatri

Question

Create an abstract class shape in which area abstract function is there so two classes triangle and rectangle can override the functionality of area in shape class .Then a change of request has come as per new requirement a we have to find the area of square and area of circle also but they don’t want to override the functionality of abstract class shape but they want to implement their code?And area of circle is Pi r2 and area of square is (side)2.Q3) Write overloaded methods to find total salary of employees. Create a class Employee and write an overloaded method to find total salary of employee.Total salary=salary + Bonus+ incentives (data types use it decimal,int,int) Total salary=salary +HRA + PF (data types use it double,float,int)Total salary=salary + perks +travelling_allowences (data types use it is float,int,short)Create another subclass as EmployeeJunior and there also write one overloaded method and call al the methods as per the parameters passed in the main method in console application.
