Arithmetic Operators


In programming, the Mathematical operations are very useful because most of the time we are dealing with mathematical concepts in programming. We know that computers can perform a mathematical calculation much faster than humans. Also the computer doesn’t have the capacity to do calculations without receiving any instructions from the computer user. Using Visual Basic, we are able to give instructions to the computer to perform mathematical operations such as Multiplication, Division, Addition, Subtraction and other kinds of arithmetic operations.

List of Arithmetic Operators in Visual Basic.

Sysmbol	Name
*	Multiplication
/	Division
+	Addition
-	Subtraction
\	Integer Division
Mod	Modolo
^	Exponentiation

This time, we’re going to create a program performing the Arithmetic Operators. To do this, open Visual Basic and create a new project then save it as “Arithmetic Operators”. Next, add two textbox, six labels and a button.

Deigning the Object Properties.

Object		Property		Settings
Textbox1	Name			txtinput1
Textbox2	Name			txtinput2
Label1		Name			lblmul
		Text			0
Label2		Name			lbldiv
		Text			0
Label1		Name			lbladd
		Text			0
Label1		Name			llblsub
		Text			0
Button1	        Name			btncompute
		Text			Compute

Then,arrange all object looks like as shown below.

At this time, we will add functionality to our application. To do this, double click the” Compute” button and add the following code:

  1. Dim input1 As Integer
  2. Dim input2 As Integer
  3.  
  4. input1 = txtinput1.Text ' assign value to a variable
  5. input2 = txtinput2.Text
  6.  
  7. lblmul.Text = input1 * input2 ' compute for Multiplication
  8. lbldiv.Text = input1 / input2 ' compute for Division
  9. lbladd.Text = input1 + input2 ' compute for Addition
  10. lblsub.Text = input1 - input2 ' compute for Subttraction

After adding the code above, you can now test your application by pressing “F5”.

Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. After downloading it, you will need a program like Winzip to decompress it.

Virus note: All files are scanned once-a-day by SourceCodester.com for viruses, but new viruses come out every day, so no prevention program can catch 100% of them.

FOR YOUR OWN SAFETY, PLEASE:

1. Re-scan downloaded files using your personal virus checker before using it.
2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
