The sum of the squares of the first ten natural numbers is,

1² + 2² + … + 10² = 385

The square of the sum of the first ten natural numbers is,

(1 + 2 + … + 10)² = 55² = 3025

Hence the difference between the sum of the squares of the first ten natural numbers and the square of the sum is 3025 385 = 2640.

Find the difference between the sum of the squares of the first one hundred natural numbers and the square of the sum.

My solution:
[sourcecode language="vbnet"]
Public Sub Difference()
    Dim iStart, iEnd, iSumOfSquares, iSquareOfSum As Integer
    iStart = 1
    iEnd = 100
    iSumOfSquares = 0
    iSquareOfSum = 0

    For iCounter As Integer = iStart To iEnd
        iSumOfSquares = iSumOfSquares + iCounter ^ 2
        iSquareOfSum = iSquareOfSum + iCounter
    Next

    Response.Write(iSquareOfSum ^ 2 – iSumOfSquares)
End Sub
