Script 3: Write a script to calculate the Simple Interest.

Dim Principal, Time, Rate, SimpleInterest

Principal = CDbl (InputBox ("Please enter the Principal"))

Time = CDbl (InputBox ("Please enter the Time"))

Rate = CDbl (InputBox ("Please enter the Rate"))

SimpleInterest = (Principal * Time * Rate)/100

MsgBox SimpleInterest

Script 2: Write a script to find the area of a triangle.

Dim Base, Height, Area

Base = CDbl (InputBox ("Please enter the Base"))

Height = CDbl (InputBox ("Please enter the Height"))

Area = 0.5 * Base * Height

MsgBox Area

Script 1: Accept two numbers from the user and print the sum of two numbers.

Dim Sum

Number1 = CInt (InputBox ("Please enter the number 1"))

Number2 = CInt (InputBox ("Please enter the number 2"))

Sum = Number1 + Number2

Msgbox Sum

Type Conversion:

CInt: Converts any value into an Integer.

CDbl: Converts any value into a Double.

CLng: Converts any value into a Long.

CBool: Converts any value into a Boolean.

CStr: Converts any value into a String.

Comment in VBScript:

• Single quote (‘) is used to comment a particular line or statement.
• No multi line comment is VB

Example:

‘This is an example of comment

Msgbox "Hello World"

TypeName:

TypeName is a keyword which tells the kind of value held by a Variable.

Example:
Dim a
a="VBScript" : b=123
Msgbox TypeName (a)
Msgbox TypeName (b)

OutPut:
String
Integer

Data Types:

• VBScript has only one data type called a Variant.
• A Variant is a special kind of data type that can contain different kinds of information, depending on how it is used. Because Variant is the only data type in VBScript, it is also the data type returned by all functions in VBScript.
• At its simplest, a Variant can contain either numeric or string information. A Variant behaves as a number when you use it in a numeric context and as a string when you use it in a string context. That is, if you are working with data that looks like numbers, VBScript assumes that it is numbers and does what is most appropriate for numbers. Similarly, if you're working with data that can only be string data, VBScript treats it as string data. You can always make numbers behave as strings by enclosing them in quotation marks (" ").
