Develop Employee Management System for the company. Create the class library which will have class Employee with the following details :

Employee ID, Employee Name, Salary, HRA, TA, DA, PF, TDS, Net Salary, Gross Salary

• Write method for accepting values of Employee ID, Employee Name, Salary, HRA, TA, DA, PF from user (From these HRA, TA, DA, PF are in percentage).

o If user do not provide any value for HRA, TA, DA and PF. Then use the optional values for these as follows:

HRA – 20%, TA – 10%, DA – 50%, PF – 12%

o Calculate TDS, Gross Salary and Net Salary as follow:

Gross Salary = Salary + HRA + TA + DA

TDS = 10% of Salary

Net Salary = Gross Salary – (PF + TDS)

Let’s build a sample banking program to perform the common tasks like Withdraw and Deposit. 

Create a C# console application that prints the Area of a square.

The application must use OOP concepts:

 Create an abstract class named ShapesClass.

 ShapesClass must contain an abstract method named Area.

 Create a class named Square that inherits from ShapesClass.

 Square class must contain a Square method.

 Create a method named Area that will override abstract method Area, and then return the sides of the square.

 In the main method create an object of the square class, with the value of the side. Print the Area of the square.

Adapt the following code to run in a windows form and also add a button to reset the input length and width boxes.

namespace PaintingEstimate

{

  class Program

  {

    static void Main(string[] args)

    {

      Console.WriteLine("Program computes the cost of painting the room");

      //inputs room length and width

      Console.Write("Enter room length: ");

      int length = Convert.ToInt32(Console.ReadLine());

      Console.Write("Enter room width: ");

      int width = Convert.ToInt32(Console.ReadLine());

      //calls method

      int totalPrice = ComputePrice(length, width);

      Console.WriteLine("Total price: ${0}", totalPrice);

      Console.ReadKey();

    }

    //method computes work price

    static int ComputePrice(int length, int width)

    {

      //price per square foot

      int price = 6;

      //ceiling

      int ceil = 9;

      int totalSquare = width * ceil * 2 + length * ceil * 2;

      return price * totalSquare;

    }

  }

}
