Question

Create a GUI C#  application that solve the following problem:

The heating system in a school should be switched on if the average temperature is less than 17 degrees Celsius. The average temperature is found from the temperatures in the Art, English and Music departments. You are required to write a program that allows the user to input 3 temperatures. The program calculates and displays the average temperature and then displays "heating should be on " or " heating should be off" as appropriate.

Answer 1

Dear Student ,

As per the requirement submitted above , kindly find the below solution.

Here a new Windows Forms Application in C# is created using Visual Studio 2017 with name "heatingSystem".This application contains a form with name "Form1.cs".Below are the files associated with form1.

1.Form1.cs[Design]

Heating System Enter Tempratures in Departments Arts English Music Calculate Average Temprature Exit

{
components.Dispose();
}
base.Dispose(disposing);
}
