* Project Name: Problem Six | |
* Solution Name: Problem Six | |
* Original creation date: 06/07/2011 | |
* Edit date: 18/01/2013 | |
* Programmer name: Jamie Taylor (aka "GaProgMan") | |
* File name: ProblemSix.c | |
* | |
* Purpose of this project: | |
* Problem Six, from Project Euler. | |
* URL: http://projecteuler.net/index.php?section=problems&id=6 | |
* The sum of the squares of the first ten natural numbers is, | |
* 1^2 + 2^2 + ... + 10^2 = 385 | |
* The square of the sum of the first ten natural numbers is, | |
* (1 + 2 + ... + 10)^2 = 55^2 = 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. | |
