HW#10 hw10ec.cpp (this problem is similar to p220 problem 3 in Savitch, Absolute C++ 3rd Ed) Write a function that compute the standard deviation of an array of an arbitrary number of floats. You may implement this array as a partially filled array or as a dynamic array. Write your code such that you can change the number of floats by changing one variable. You can use the following as a hint or small guide to your function: Your function should first compute the average. It should then compute the sum. Lastly compute and return the standard deviation as a float.
