  • textBox2: Text box for entering the second number.
  • label1: Label displaying the operation symbol.
  • button1: Addition button (+).
  • button2: Subtraction button (-).
  • button3: Multiplication button (*).
  • button4: Division button (/).
  • label2: Label displaying the result.

Event Handlers

The main function is the entry point of the application. It sets up the necessary configurations for the Windows Forms application, creates an instance of the MyForm class, and starts the application by running the message loop for the form instance.

Notes

  • The application performs integer arithmetic operations. Ensure that the input values are valid integers.
  • Error handling and input validation are not implemented in this basic version.
  • Feel free to enhance the application by adding additional features, such as support for floating-point operations, error handling, and input validation.
