Example 1 : Addition of Numeric Values
Assume variable A holds 15 and variable B holds 20 then -
<!DOCTYPE html>
<html>
<body>
<script language="vbscript" type="text/vbscript">
Dim a : a = 15
Dim b : b = 20
Dim result
result = a + b
Document.write ("Result of Operation " & result) 'Numeric addition
result = a & b
Document.write ("Result of Operation " & result) 'Concatenate two numbers
</script>
</body>
</html>
After running program in IE following output will be produced -
Result of Operation 35 Result of Operation 1520
Example 2 : Addition of String Values
Assume variable A holds 15 and variable B holds 20 then -
<!DOCTYPE html>
<html>
<body>
<script language="vbscript" type="text/vbscript">
Dim a : a = "google."
Dim b : b = "com"
Dim result
result = a + b
Document.write ("Result of Operation " & result) 'Concatenate two strings
result = a & b
Document.write ("Result of Operation " & result) 'Concatenate two numbers
</script>
</body>
</html>
After running program in IE following output will be produced -
Result of Operation google.com Result of Operation google.com
