Objective
Given a list of N integers, find its basic statistics (as in previous exercise), root-mean-square and standard deviation. Your program will first ask for N, the number of integers in the list, which the user will input. Then the user will input N more numbers.
You need to use array or vector (optional, but encouraged) to store the numbers. You also need to use functions for each calculation.
Note:
Refer to Vector spec in http://www.cplusplus.com/reference/stl/vector/
Input Format:
Your program will loop on user input and print out basic statistics until user stops.
Output Format:
Try your imagination.
More:
<+> Have you tried different way of getting the input numbers? What difference does it make if the numbers are floating point?
<+> Do you use one function for each calculation, min(), max(), avg(), sd()? Can you do one function which does more than one calculations, such as statistics(avg, mean, sd)?
<++> For those who are bored of array, what if all the numbers are stored in a file? Do you still need "count"? How about replace cin with file input?
