Concatenation Operators in VBScript

Advertisements


Following table shows all the Concatenation operators supported by VBScript language. Assume variable A holds 5 and variable B holds 10, then:

OperatorDescriptionExample
+Adds two Values as Variable Values are Numeric A + B will give 15
&Concatenates two Values A & B will give 510

Example

Try the following example to understand the Concatenation operator available in VBScript:

<!DOCTYPE html>
<html>
<body>
<script language="vbscript" type="text/vbscript">
  Dim a : a = 5
  Dim b : b = 10
  Dim c

  c=a+b 
  Document.write ("Concatenated value:1 is " &c) 'Numeric addition 
  Document.write ("<br></br>")  'Inserting a Line Break for readability
  c=a&b 
  Document.write ("Concatenated value:2 is " &c) 'Concatenate two numbers 
  Document.write ("<br></br>")  'Inserting a Line Break for readability
</script>
</body>
</html>

When you save it as .html and execute it in Internet Explorer, then the above script will produce the following result:

Concatenated value:1 is 15

Concatenated value:2 is 510

Concatenation can also be used for concatenating two strings. Assume variable A="Microsoft" and variable B="VBScript" then:

OperatorDescriptionExample
+Concatenates two Values A + B will give MicrosoftVBScript
&Concatenates two Values A & B will give MicrosoftVBScript

Example

Try the following example to understand the Concatenation operator available in VBScript:

<!DOCTYPE html>
<html>
<body>
<script language="vbscript" type="text/vbscript">
  Dim a : a = "Microsoft"
  Dim b : b = "VBScript"
  Dim c

  c=a+b 
  Document.write ("Concatenated value:1 is " &c) 'Numeric addition 
  Document.write ("<br></br>")  'Inserting a Line Break for readability
  c=a&b 
  Document.write ("Concatenated value:2 is " &c) 'Concatenate two numbers 
  Document.write ("<br></br>")  'Inserting a Line Break for readability
</script>
</body>
</html>

When you save it as .html and execute it in Internet Explorer, then the above script will produce the following result:

Concatenated value:1 is MicrosoftVBScript

Concatenated value:2 is MicrosoftVBScript
