Question

Design and implement a GUI application that uses text fields to obtain two integer values (one text field for each value) along with a button named "display" to display the sum and product of the values. Assume that the user always enters valid integer values as inputs.

Answer 1

Public Class Form1

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

Dim sum, product, num1, num2 As Integer

num1 = Val(TextBox1.Text)

num2 = Val(TextBox2.Text)

sum = num1 + num2

product = num1 * num2

TextBox3.Text = sum

TextBox4.Text = product

End Sub

End Class

• Step-by-step explanation:
• The solution is implemented in Visual Basic Programming Language
• Two textboxes are created to receive the user's input and two textboxes for displaying sum and product respectively
• Each of these controls are appropriately labeled (See the attached GUI interface)
• The Sum is calculated by adding the values from textbox1 and 2
• The product is calculated by multiplying both
