Standard Deviation
Write a program that can calculate the standard deviation of a set of numbers, which were entered from the keyboard at the run time.
The standard deviation was defined in the URL: Standard deviation - Wikipedia, the free encyclopedia .
For calculating variance, use the formula III - On-line algorithm listed at: Algorithms for calculating variance - Wikipedia, the free encyclopedia
