Write a short program to calculate the average and standard deviation of a group of numbers. Start by asking a user how many values they are entering. Then allow then to enter in that many number of double values into an array. Using a loop run through the values and calculate the average of the set. Using the formula for calculating standard deviation in problem 11 on page 627 of the text, loop through the values again and calculate this as well. Output the results to the screen. If time allows, protect the program from the user entering in non-numerical values.
