VB Script Interview Questions & Answers - Learning Mode

VBScript ("Visual Basic Scripting Edition") is an Active Scripting language developed by Microsoft that is modeled on Visual Basic. It is designed as a "lightweight" language with a fast interpreter for use in a wide variety of Microsoft environments.

Question: Why use Style Sheets?

Answer: Style sheets allow a much greater degree of layout and display control than has ever been possible thus far in HTML.

Style sheets are also backward compatible - They can be mixed with HTML styling Source: CoolInterview.com
Question: How Do I Use Arrays?

Answer: Arrays may either be static or dynamic. A static array has its dimensions pre-defined and may not be re-sized, whereas a dynamic array does not have a pre-defined number of dimensions and must be resized to store any data. To define any of the two arrays first use either the Dim, Public, or Private statments as you would with a normal variable. Then, to define a one-dimensional static array with three elements, you could go:
Dim myArray(2)
To assign values to each element go:
