1. There are various selection structures that can be used in programming. What are the different relational operators used in selection structures? Provide an example of an if-then-else statement that can be used in a script that performs a system administration task.

ANSWER
Here\’s a VBScript code that takes three parameters (numbers), calculates their product, sum, and average, and optionally saves the results to a file \”Results.txt\” using the redirection operator:

“`vbscript
\’**********************************************************************
\’ Script: w2_firstname_lastname.vbs
\’ Description: Calculate product, sum, and average of three numbers.
\’ Usage: cscript.exe w2_firstname_lastname.vbs > Results.txt
\’ Example: cscript.exe w2_firstname_lastname.vbs 2 3 5 > Results.txt
\’**********************************************************************

\’ Check the number of command-line arguments
If WScript.Arguments.Count < 3 Then WScript.Echo \"Usage: cscript.exe w2_firstname_lastname.vbs > Results.txt\”
WScript.Quit
End If

\’ Get the command-line arguments as numbers
num1 = WScript.Arguments(0)
num2 = WScript.Arguments(1)
num3 = WScript.Arguments(2)

\’ Calculate product, sum, and average
product = num1 * num2 * num3
sum = num1 + num2 + num3
average = (num1 + num2 + num3) / 3

\’ Display the results
WScript.Echo \”Product of the three numbers: \” & product
WScript.Echo \”Sum of the three numbers: \” & sum
WScript.Echo \”Average of the three numbers: \” & average
“`

Save this script as \”w2_firstname_lastname.vbs\” and run it as shown in your sample run example:

“`
cscript.exe w2_firstname_lastname.vbs 2 3 5 > Results.txt
“`

This script will calculate the product, sum, and average of the three numbers and print the results. If you use the redirection operator (\”>\”), it will also save the results to a file named \”Results.txt.\”
