Question

Create a C++ Program to do the following:

Create a .txt file with up to 10 double numbers. Then in your code, create an array to hold 10 doubles. Open
the file. Read each number from the file into a place in the array. Count how many numbers you read. Close the
file.
Now, go through the data in the array twice. Don’t go through all 10 elements in the array, only the elements
for which you have read data. On the first pass, calculate the average of the numbers in the array. (Calculate the
total, divide by count, that is µ).
On the second pass through the data, for each number you should calculate how far it is from the average
(number - average), square that, and keep a sum of the squares, that is S.
When you’re done, calculate the average of that sum of squares, A. The square root of that number, σ is your
standard deviation.
Print out the average µ and standard deviation σ
